Process for separating anthracite coal from impurities  

SciTech Connect (OSTI)

A process is described for separating a first mixture including previously mined anthracite coal, klinker-type cinder ash and other refuse consisting of: a. separating the first mixture to produce a refuse portion and a second mixture consisting of anthracite and klinker-type cinder ash, b. reducing the average particle size in the second mixture to a uniform size, c. subjecting the second mixture to a separating magnetic field to produce a klinker-type cinder ash portion and an anthracite coal portion.

Fine Anthracite Coal Washing Using Spirals  

SciTech Connect (OSTI)

The spiral performed well in cleaning the coarse 8 x 16 mesh size fraction, as demonstrated by the Ep ranging from 0.091 to 0.177. This is in line with typical spiral performance. In addition, the presence of the coarser size fraction did not significantly affect spiral performance on the typical 16 x 100 mesh fraction, in which the Ep ranged from 0.144 to 0.250. Changes in solids concentration and flow rate did not show a clear correlation with spiral performance. However, for difficult-to-clean coals with high near-gravity material, such as this anthracite, a single-stage spiral cleaning such a wide size fraction may not be able to achieve the clean coal ash and yield specifications required. In the first place, while the performance of the spiral on the coarse 8 x 16 mesh fraction is good with regard to Ep, the cutpoints (SG50s) are high (1.87 to 1.92), which may result in a clean coal with a higher-than-desired ash content. And second, the combination of the spiral's higher overall cutpoint (1.80) with the high near-gravity anthracite results in significant misplaced material that increases the clean coal ash error. In a case such as this, one solution may be to reclean the clean coal and middlings from the first-stage spiral in a second stage spiral.

Co-carbonization of two anthracites with a fat coal or two pitches  

SciTech Connect (OSTI)

The blends of two anthracite powders (YQ and JC) with a fat coal (C4) or a petroleum pitch (PP) or a coal tar pitch (CTP) in different proportions were co-carbonized at 3{sup o}C/min up to 1000{sup o}C in an experimental 1 kg coke oven. Coke yield, coke particulate size, coke micro-strength and coke cracking strength were measured respectively. Coke optical textures were watched under a microscope. The results show that as anthracite proportion increases, coke yields of all blends improve; > 0.8 mm lump coke yields of blends with CTP or PP decline slightly, blends with C4 drop heavily; coke microstrengths do not change sharply, and coke cracking strength of blends with C4 or PP decrease more than blends with CTP. C4 produces fine-grained mosaics, and two anthracites are mainly fusinite and fragments, PP is coarse-grained mosaics, and CTP is chiefly flow or domain textures. Independent optical textures were observed in cokes. There exist evident borders between the two contact optical textures which were produced by different components, and a few phenomena that domain or flow textures penetrating into fusinite appeared in the blends. It seems that CTP is the best adhesives for blending with anthracites for producing high quality cokes.

Combustion of high-sulfur coal and anthracite wastes in a rotary kiln combustor with an advanced internal air distributor  

SciTech Connect (OSTI)

Fluid bed combustors have received extensive testing with both high-sulfur coal and anthracite wastes. Rotary kilns are effective and popular devices for waste combustion. The Angelo Rotary Furnace{trademark} has been developed to improve the operation of rotary pyrolyzer/combustor systems through enhanced air distribution, which in this process is defined as staged, swirled combustion air injection. Fourteen of these new furnaces have been installed worldwide. Two units in Thailand, designed for rice hull feed with occasional lignite feed, have been recently started up. An older unit in Pennsylvania is being upgraded with a new, more advanced air distribution system for a series of tests this fall in which inexpensive high-sulfur coal and anthracite wastes will be fired with limestone. The purposes of these tests are to determine the burning characteristics of these two fuels in this system, to discover the Ca/S ratios necessary for operation of a rotary kiln combusting these fuels, and to observe the gas-borne emissions from the furnace. An extensive preliminary design study will be performed on a commercial installation for combustion of anthracite wastes. 14 refs., 5 figs., 1 tab.

The mechanism of coking pressure generation II: Effect of high volatile matter coking coal, semi-anthracite and coke breeze on coking pressure and contraction  

Science Journals Connector (OSTI)

One of the most important aspects of the cokemaking process is to control and limit the coking pressure since excessive coking pressure can lead to operational problems and oven wall damage. Following on from a previous paper on plastic layer permeability we have studied the effect of contraction of semi-coke on coking pressure and the effect of organic additives on contraction. A link between contraction (or simulated contraction) outside the plastic layer and coking pressure was demonstrated. The interaction between this contraction, local bulk density around the plastic layer and the dependence of the permeability of the plastic layer on bulk density was discussed as possible mechanisms for the generation of coking pressure. The effect of blending either a high volatile matter coal or one of two semi-anthracites with low volatile matter, high coking pressure coals on the coking pressure of the binary blends has been explained using this mechanism.

Plant betterment for an anthracite-burning utility in Ukraine: Coal preparation as part of a SO{sub 2}, NO{sub x}, and particulate emission control strategy  

SciTech Connect (OSTI)

Workers at the Energy Departments of the US and Ukraine have cooperatively devised a strategy for upgrading performance of a 200 MWe wet bottom pulverized coal boiler in eastern Ukraine at the Lugansk GRES power station. The plant currently burns poor quality anthracite (30% ash versus 18% ash design coal, as-received basis) and is in need of maintenance. Oil or gas support fuel in the amount of 30% (calorific basis) is required to stabilize the flame and supplement the calorific value of the coal feed. No NO{sub x} or SO{sub 2} controls are used at present, and unburned carbon content in the fly ash is high. An experimental program was carried out at the Federal Energy Technology Center (FETC) to estimate the improvement in plant performance that could be expected if the unit is supplied with design coal and is refurbished. High ash Ukrainian anthracite was cleaned to design specifications. Raw and cleaned coal were fed to a 490 MJ/h coal feed combustion unit at a number of conditions of support fuel use and ingress air leakage designed to simulate current and improved operations at the power plant. The results indicate the improvement in performance and reductions in SO{sub 2} and NO{sub x} emissions that can be expected as a result of the planned upgrade and conversion to use of cleaned coal. A detailed engineering and financial analysis indicates that plant rehabilitation combined with the use of cleaned schtib reduces not only pollutant emissions but also cost of electricity (COE). Additional benefits include increased plant life and capacity, and reduced supplementary fuel consumption.

Create a Consortium and Develop Premium Carbon Products from Coal  

SciTech Connect (OSTI)

The objective of these projects was to investigate alternative technologies for non-fuel uses of coal. Special emphasis was placed on developing premium carbon products from coal-derived feedstocks. A total of 14 projects, which are the 2003 Research Projects, are reported herein. These projects were categorized into three overall objectives. They are: (1) To explore new applications for the use of anthracite in order to improve its marketability; (2) To effectively minimize environmental damage caused by mercury emissions, CO{sub 2} emissions, and coal impounds; and (3) To continue to increase our understanding of coal properties and establish coal usage in non-fuel industries. Research was completed in laboratories throughout the United States. Most research was performed on a bench-scale level with the intent of scaling up if preliminary tests proved successful. These projects resulted in many potential applications for coal-derived feedstocks. These include: (1) Use of anthracite as a sorbent to capture CO{sub 2} emissions; (2) Use of anthracite-based carbon as a catalyst; (3) Use of processed anthracite in carbon electrodes and carbon black; (4) Use of raw coal refuse for producing activated carbon; (5) Reusable PACs to recycle captured mercury; (6) Use of combustion and gasification chars to capture mercury from coal-fired power plants; (7) Development of a synthetic coal tar enamel; (8) Use of alternative binder pitches in aluminum anodes; (9) Use of Solvent Extracted Carbon Ore (SECO) to fuel a carbon fuel cell; (10) Production of a low cost coal-derived turbostratic carbon powder for structural applications; (11) Production of high-value carbon fibers and foams via the co-processing of a low-cost coal extract pitch with well-dispersed carbon nanotubes; (12) Use of carbon from fly ash as metallurgical carbon; (13) Production of bulk carbon fiber for concrete reinforcement; and (14) Characterizing coal solvent extraction processes. Although some of the projects funded did not meet their original goals, the overall objectives of the CPCPC were completed as many new applications for coal-derived feedstocks have been researched. Future research in many of these areas is necessary before implementation into industry.

Broader source: Energy.gov (indexed) [DOE]

2 2 Coal Coal is a mixture of organic mineral material produced by a natural process of growth and decay, or an accumulation of debris both vegetal and mineral with some sorting and stratification. The process is accomplished by chemical, biological, bacteriological and metamorphic action. 1 Forms of Coal Coal is a hydrocarbon that is classified according to the amount of heat it produces. Heat content depends upon the amount of fixed carbon it contains. Rank is the degree of progressive alteration in the transformation from lignite to anthracite. There are four primary ranks of coal: * Anthracite (semi-anthracite, anthracite, and meta-anthracite) * Bituminous (high-volatile, medium-volatile, and low-volatile) * Subbituminous * Lignite (brown coal and lignite)

Opportunities for coal to methanol conversion  

SciTech Connect (OSTI)

The accumulations of mining residues in the anthracite coal regions of Pennsylvania offer a unique opportunity to convert the coal content into methanol that could be utilized in that area as an alternative to gasoline or to extend the supplies through blending. Additional demand may develop through the requirements of public utility gas turbines located in that region. The cost to run this refuse through coal preparation plants may result in a clean coal at about $17.00 per ton. After gasification and synthesis in a 5000 ton per day facility, a cost of methanol of approximately $3.84 per million Btu is obtained using utility financing. If the coal is to be brought in by truck or rail from a distance of approximately 60 miles, the cost of methanol would range between $4.64 and $5.50 per million Btu depending upon the mode of transportation. The distribution costs to move the methanol from the synthesis plant to the pump could add, at a minimum, $2.36 per million Btu to the cost. In total, the delivered cost at the pump for methanol produced from coal mining wastes could range between $6.20 and $7.86 per million Btu.

A compact XRF unit for determining total sulphur content in coals  

SciTech Connect (OSTI)

A microcomputer based x-ray fluorescence (XRF) unit was developed for off-line determination of total sulphur content in coal samples. The unit consisted of the x-ray exciting/measuring set and the microcomputer with a plug-in interface card, An Fe-55 radioisotope was used as the exciting source while a krypton-filled proportional counter was used to measure x-rays from the samples. The x-ray spectrum was simultaneously displayed on the microcomputer screen. For quantitative determination of sulphur, the intensities of sulphur K x-rays as well as calcium K x-rays and scattered x-rays were taken into account. The unit was tested with finely-ground, dried and compressed lignite, subbituminous and bituminous samples. It was found that for low-calcium coals the results were in good agreement with those obtained from the standard chemical analysis method within {+-}0.2 %S and within {+-}0.5 %S for high-calcium coals.

Thermodynamic properties of pulverized coal during rapid heating devolatilization processes. Quarterly progress report, April--June 1993  

SciTech Connect (OSTI)

Knowledge of the thermodynamic and morphological properties of coal associated with rapid heating decomposition pathways is essential to progress in coal utilization technology. Specifically, knowledge of the heat of devolatilization, surface area and density of coal as a function of rank characteristics, temperature and extent of devolatilization in the context of rapid heating conditions is essential to the fundamental determination of kinetic parameters of coal devolatilization. These same properties are also needed to refine existing devolatilization sub-models utilized in large-scale modeling of coal combustion systems. The objective of this research is to obtain data on the thermodynamic properties and morphology of coal under conditions of rapid heating. Specifically, the total heat of devolatilization, external surface area, BET surface area and true density will be measured for representative coal samples. The coal ranks to be investigated will include a high volatile A bituminous (PSOC 1451 D) and a low volatile bituminous (PSOC 1516D). An anthracite (PSOC 1468) will be used as a non-volatile coal reference. In addition, for one coal, the contribution of each of the following components to the overall heat of devolatilization will be measured: the specific heat of coal/char during devolatilization, the heat of thermal decomposition of the coal, the specific heat capacity of tars, and the heat of vaporization of tars.

Eisenbeis, Supt. of Conservation THE FIRST COAL PLANTS Coal has been called "the mainspring" of our civilization. You are probably familiar, in a general way, with the story of how it originated ages ago from beds of peat which were very slowly changed to coal; and how it became lignite or brown coal, sub-bituminous, bituminous, or anthracite coal, depending on bacterial and chemical changes in the peat, how much it was compressed under terrific pressure, and the amount of heat involved in the process. You also know that peat is formed by decaying vegetation in shallow clear fresh-water swamps or bogs, but it is difficult to find a simple description of the kinds of plants that, living and dying during different periods of the earth's history, created beds of peat which eventually became coal.

The status of coal briquetting technology in Korea  

SciTech Connect (OSTI)

Anthracite is the only indigenous fossil fuel resource produced in Korea and is an important main source of residential fuel. Due to its particular characteristics, the best way to use Korean coal is in the form of briquettes, called {open_quotes}Yontan.{close_quotes} The ability to use this coal as briquettes was a great discovery made nearly 50 years ago and since then, has made a great contribution to the energy consumption of low and middle income households. Korean anthracite in coal briquette form has been used widely for household heating purposes. Collieries in Korea produced no more than one million tons of anthracite annually in the 1960s. Production, however, increased substantially up to about 17 million tons per year in the mid-1970s. In 1986, Korea succeeded in raising its coal production to 24.2 million tons, which was the maximum production level achieved by the Korean coal industrial sector. Since then, anthracite production has fallen. In 1991, coal output dropped to 15.1 million tons, a decrease of 12.2 percent from the 17.2 million tons produced in 1990, due to falling coal demand and rising labor costs. The role of coal as an energy source will be more important in the future to meet projected economic growth in Korea. While the production of indigenous Korean anthracite is expected to decrease under a coal mining rationalization policy, imports of bituminous coal will increase rapidly and will be used as an oil substitute in industry and power generation. In this chapter, general aspects of the Korean coal industry and coal utilization for residential uses, especially the Yontan coal briquetting techniques, are discussed. In addition, coal briquetting technology applications suitable for the APEC region will be presented.

The structural alignment of coal and the analogous case of Argonne Upper Freeport coal  

Science Journals Connector (OSTI)

It has long been recognized that coal is somewhat aligned. Multiple techniques imply a structural alignment but its quantification has been challenging. Moreover, discrepancies exist among techniques as to whether low-rank coals are aligned. The extent of structural alignment for the rank range was quantified directly via image analysis of high-resolution transmission electron micrograph lattice fringes. Alignment was quantified, for each coal, by the contribution to the total fringe length within the prominent 45° of orientation over random orientation (1/4 of the possible orientations). It was evident that there is structural alignment across the rank range. Thus it is time for the community to desist from making the erroneous statement that: low-rank coals are randomly oriented. The slight orientation was similar for low-rank Beulah-Zap lignite and Illinois No. 6 bituminous coals (24% and 22%) with Pocahontas (lvb) coal showing slightly greater (39%) alignment with extensive alignment (65%) in the case of an anthracite coal. The degree of ordering is illustrated with the aid of false-color lattice fringe images and Rose diagrams. The fringe contribution 90° opposed to the maximum length contribution had the minimum or near minimum percentage length contribution for all coals except Upper Freeport and to a lesser degree Illinois No. 6. For the Upper Freeport coal the alignment is lower than expected given its mvb rank (14% over random) and is attributed to a variant of T-stacking for the small aromatic moieties sited perpendicular and between horizontal displaced fringes.

Coal Coal Jump to: navigation, search Dictionary.png Coal A combustible black or brownish-black sedimentary rock composed mostly of carbon and hydrocarbons. It is formed from plant remains that have been compacted, hardened, chemically altered, and metamorphosed by heat and pressure over geologic time (typically millions of years). It is the most abundant fossil fuel produced in the United States.[1][2] View on Wikipedia Wikipedia Definition Coal (from the Old English term col, which has meant "mineral of fossilized carbon" since the 13th century) is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers or veins called coal beds or coal seams. The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later

Coal liquefaction process using pretreatment with a binary solvent mixture  

DOE Patents [OSTI]

An improved process for thermal solvent refining or hydroliquefaction of non-anthracitic coal at elevated temperatures under hydrogen pressure in a hydrogen donor solvent comprises pretreating the coal with a binary mixture of an aromatic hydrocarbon and an aliphatic alcohol at a temperature below 300 C before the hydroliquefaction step. This treatment generally increases both conversion of coal and yields of oil. 1 fig.

Conventional coal preparation in the United States  

SciTech Connect (OSTI)

Processing of bituminous and anthracite coal is widely practiced in the United States and, as mentioned earlier, about 80 percent of the production of these coals is processed as clean coal in preparation plants. Subbituminous coal is not widely processed, primarily because these low rank raw coals are low in sulfur (0.5 to 1.0 percent) and relatively low in ash (8 to 15 percent). They are also relatively low in heat content due to their high inherent moisture. Lignite coals, to the best of the authors{close_quote} knowledge, are not presently being processed in Conventional Coal Preparation plants. This is due to their unstable nature and putting them in water in a coal preparation plant is likely to cause severe degradation in particle size and add to their already high inherent moisture content. The following are the benefits of clean coal processing: produces a uniform product which can be utilized more efficiently; produces a higher quality product which results in higher efficiency at the power station or the steel mill; reduces sulfur dioxide and other adverse stack emissions during coal firing which is a very important environmental consideration; reduces ash or slag handling costs by the user; reduces shipping costs; and reduces handling and storage costs. Processing any stable raw coal in a coal preparation plant will always produce a higher grade product which is a more efficient and a more environmentally acceptable fuel for use at power stations, steel mills, home heating or industrial boilers.

Thermal-destruction products of coal in the blast-furnace gas-purification system  

SciTech Connect (OSTI)

The lean, poorly clinkering coal and anthracite used to replace coke in blast furnaces has a considerable content of volatile components (low-molecular thermaldestruction products), which enter the water and sludge of the blast-furnace gas-purification system as petroleum products. Therefore, it is important to study the influence of coal on the petroleum-product content in the water and sludge within this system. The liberation of primary thermal-destruction products is investigated for anthracite with around 4 wt % volatiles, using a STA 449C Jupiter thermoanalyzer equipped with a QMC 230 mass spectrometer. The thermoanalyzer determines small changes in mass and thermal effects with high accuracy (weighing accuracy 10{sup -8} g; error in measuring thermal effects 1 mV). This permits experiments with single layers of coal particles, eliminating secondary reactions of its thermal-destruction products.

The relationship between the thermoplastic behavior of blends and their component coals  

SciTech Connect (OSTI)

The thermoplastic behaviors of a number of coking coal blends were measured using proton magnetic resonance thermal analysis (PMRTA) to determine to what extent they were affected by interactions between the component coals. Most blends showed evidence that at temperatures near their temperatures of maximum fluidity the extent to which they fused was different to that expected if the coals did not interact. Only blends of coking coals of different rank fused to a greater extent than expected in the absence of interactions. Semi-anthracite, low rank coals and charcoal reduced the extent of fusion of coking coals to values below those expected if they were acting as inert diluents. These interactions are interpreted as being mediated by transfer of volatile material between the coals on heating.

Production characteristics and drainage optimization of coalbed methane wells: A case study from low-permeability anthracite hosted reservoirs in southern Qinshui Basin, China  

Science Journals Connector (OSTI)

Abstract Monitoring the production from 94 coalbed methane (CBM) wells in the southern part of the Qinshui Basin of China this study demonstrates production characteristics of CBM wells, and how the incorrect production system, including improper water drainage rates and wellhead pressures, can lead to diminished gas production. Using data from these wells our results suggest that high-production rate wells, medium-production rate wells, low-production rate wells, and drainage wells, are controlled by drainage conditions in addition to the well location and structural geology. The analysis of drainage parameters shows that the maximum wellhead pressure should be maintained around 1.5 MPa before stable production, and between 0.10 MPa and 0.30 MPa after stable production. The most efficient average water production rate is approximately 4 m3/day before gas production and should be maintained near 1 m3/day during gas production. Initial daily average water production rate should be maintained around 1.5 m3/day. Maximum water production rate should be regulated between 4 and 17 m3/day. The rate of water level reduction should be within 4 m/d and drainage time should be maintained for 50–200 days prior to gas production. Implementation of these optimal drainage parameters will promote and sustain peak gas production for several years. In addition, reservoirs with adequate permeability, > 0.1 mD, are ideal for electric submersible pump systems while sucker-rod pumps are better suited for reservoirs with poor permeability. The combination of these operating conditions and the appropriate pumps optimizes the extraction efficiency and recovery of coalbed methane from the anthracitic coals in the Qinshui Basin.

Small boiler uses waste coal  

SciTech Connect (OSTI)

Burning coal waste in small boilers at low emissions poses considerable problem. While larger boiler suppliers have successfully installed designs in the 40 to 80 MW range for some years, the author has been developing small automated fluid bed boiler plants for 25 years that can be applied in the range of 10,000 to 140,000 lbs/hr of steam. Development has centered on the use of an internally circulating fluid bed (CFB) boiler, which will burn waste fuels of most types. The boiler is based on the traditional D-shaped watertable boiler, with a new type of combustion chamber that enables a three-to-one turndown to be achieved. The boilers have all the advantages of low emissions of the large fluid boilers while offering a much lower height incorporated into the package boiler concept. Recent tests with a waste coal that had a high nitrogen content of 1.45% demonstrated a NOx emission below the federal limit of 0.6 lbs/mm Btu. Thus a NOx reduction on the order of 85% can be demonstrate by combustion modification alone. Further reductions can be made by using a selective non-catalytic reduction (SNCR) system and sulfur absorption of up to 90% retention is possible. The article describes the operation of a 30,000 lbs/hr boiler at the Fayette Thermal LLC plant. Spinheat has installed three ICFB boilers at a nursing home and a prison, which has been tested on poor-grade anthracite and bituminous coal. 2 figs.

Characterisation and model fitting kinetic analysis of coal/biomass co-combustion  

Science Journals Connector (OSTI)

Abstract The combustion behaviors of biomass, coal and their blends were studied by thermogravimetric analysis. Combustion parameters such as ignition, burnout, peak rate, ignition index, and combustibility index were analyzed. The kinetic parameters were optimized based on experimental results by a double parallel reactions random pore model (DRPM) proposed in this paper. The results show that the combustion characteristic temperature of the biomass is lower and maximum rate of combustion is higher than that of anthracite coal. With the increase of biomass content, ignition temperature and burnout temperature of blends tended to decrease, while the ignition index and combustibility index increased. Compared with the original RPM model, the DRPM model could not only describe the combustion process with a single peak rate, but also the combustion of biomass-coal blends with two rate peaks. The combustion activation energies of blends were extracted by DRPM model in the present study.

The US coal industry 1996  

SciTech Connect (OSTI)

Several years ago a friend and former classmate, Dr. Doug Dahl, put the coal industry into perspective. At that time he worked for Consol, whose parent company was DuPont. I will use his story, but update it with today`s statistics. As can be seen in Figure 1, total US coal production continues to show healthy growth. In 1995 we produced 1,032,000,000 tons, and 1,046,000,000 tons are projected for 1996. Unfortunately as seen in Figure 2, the average price per ton of coal sold is still dropping. The coal industry is experiencing the unusual situation of falling coal prices with increasing coal demand! In 1994 (1995 data not available) the average price for a ton of coal was only $19.41. Multiplying the two numbers, yields the total sales value for our entire industry, $20.1 billion in 1994. That`s roughly half the approximately $40 billion per year sales value for a single chemical company, DuPont, Dr. Dahl`s parent company. As Dr. Dahl pointed out, the coal industry just isn`t that big. As we can see in Figure 3, the yearly trends show that the total value of the US coal production is shrinking. The total value has fallen through the 90`s and follows the average price per ton trend. Even increases in production have generally not been enough to offset the falling prices.

Gasoline and Diesel Fuel Update (EIA)

Although coal use is expected to be displaced by natural gas in some parts of the world, Although coal use is expected to be displaced by natural gas in some parts of the world, only a slight drop in its share of total energy consumption is projected by 2020. Coal continues to dominate many national fuel markets in developing Asia. Historically, trends in coal consumption have varied considerably by region. Despite declines in some regions, world coal consumption has increased from 84 quadrillion British thermal units (Btu) in 1985 to 93 quadrillion Btu in 1997. Regions that have seen increases in coal consumption include the United States, Japan, and developing Asia. Declines have occurred in Western Europe, Eastern Europe, and the countries of the former Soviet Union (FSU). In Western Europe, coal consumption declined by 33 percent between 1985 and 1997, displaced in considerable measure by

Coal Coal picture of a printer Printer Friendly Version (PDF) Although coal use is expected to be displaced by natural gas in some parts of the world, only a slight drop in its share of total energy consumption is projected by 2020. Coal continues to dominate many national fuel markets in developing Asia. World coal consumption has been in a period of generally slow growth since the late 1980s, a trend that is expected to continue. Although 1999 world consumption, at 4.7 billion short tons,9 was 15 percent higher than coal use in 1980, it was lower than in any year since 1984 (Figure 51). The International Energy Outlook 2001 (IEO2001) reference case projects some growth in coal use between 1999 and 2020, at an average annual rate of 1.5 percent, but with considerable variation among regions.

Potential for Coal-to-Liquids Conversion in the U.S.-Resource Base  

SciTech Connect (OSTI)

By applying the multi-Hubbert curve analysis to coal production in the United States, we demonstrate that anthracite production can be modeled with a single Hubbert curve that extends to the practical end of commercial production of this highest-rank coal. The production of bituminous coal from existing mines is about 80% complete and can be carried out at the current rate for the next 20 years. The production of subbituminous coal from existing mines can be carried out at the current rate for 40-45 years. Significant new investment to extend the existing mines and build new ones would have to commence in 2009 to sustain the current rate of coal production, 1 billion tons per year, in 2029. In view of the existing data, we conclude that there is no spare coal production capacity of the size required for massive coal conversion to liquid transportation fuels. Our analysis is independent of other factors that will prevent large-scale coal liquefaction projects: the inefficiency of the process and either emissions of greenhouse gases or energy cost of sequestration.

Proximate analysis of coal  

SciTech Connect (OSTI)

This lab experiment illustrates the use of thermogravimetric analysis (TGA) to perform proximate analysis on a series of coal samples of different rank. Peat and coke are also examined. A total of four exercises are described. These are dry exercises as students interpret previously recorded scans. The weight percent moisture, volatile matter, fixed carbon, and ash content are determined for each sample and comparisons are made. Proximate analysis is performed on a coal sample from a local electric utility. From the weight percent sulfur found in the coal (determined by a separate procedure the Eschka method) and the ash content, students calculate the quantity of sulfur dioxide emissions and ash produced annually by a large coal-fired electric power plant.

Most of the coal delivered to U.S. consumers is transported by railroads, which accounted for 64% of total domestic coal shipments in 2004. Trucks transported approximately 12% of the coal consumed in the United States in 2004, mainly in short hauls from mines in the East to nearby coal-fired electricity and industrial plants. A number of minemouth power plants in the West also use trucks to haul coal from adjacent mining operations. Other significant modes of coal transportation in 2004 included conveyor belt and slurry pipeline (12%) and water transport on inland waterways, the Great Lakes, and tidewater areas (9%).

Coal surface control for advanced physical fine coal cleaning technologies  

SciTech Connect (OSTI)

This final report presents the research work carried out on the Coal Surface Control for Advanced Physical Fine Coal Cleaning Technologies project, sponsored by the US Department of Energy, Pittsburgh Energy Technology Center (DOE/PETC). The project was to support the engineering development of the selective agglomeration technology in order to reduce the sulfur content of US coals for controlling SO[sub 2] emissions (i.e., acid rain precursors). The overall effort was a part of the DOE/PETCs Acid Rain Control Initiative (ARCI). The overall objective of the project is to develop techniques for coal surface control prior to the advanced physical fine coal cleaning process of selective agglomeration in order to achieve 85% pyrite sulfur rejection at an energy recovery greater than 85% based on run-of-mine coal. The surface control is meant to encompass surface modification during grinding and laboratory beneficiation testing. The project includes the following tasks: Project planning; methods for analysis of samples; development of standard beneficiation test; grinding studies; modification of particle surface; and exploratory R D and support. The coal samples used in this project include three base coals, Upper Freeport - Indiana County, PA, Pittsburgh NO. 8 - Belmont County, OH, and Illinois No. 6 - Randolph County, IL, and three additional coals, Upper Freeport - Grant County- WV, Kentucky No. 9 Hopkins County, KY, and Wyodak - Campbell County, WY. A total of 149 drums of coal were received.

SciTech Connect (OSTI)

Coal Production 1984 provides comprehensive information about US coal production, the number of mines, prices, productivity, employment, productive capacity, reserves, and stocks to a wide audience including Congress, federal and state agencies, the coal industry, and the general public. The data were collected and published by the Energy Information Administration (EIA), to fulfill its data collection and dissemination responsibilities as specified in the Federal Energy Administration Act of 1974 (PL 93-275) as amended. All data presented in this report, except the total production table presented in the Highlights section, the demonstrated reserve base data presented in Appendix A, and the 1983 coal preparation and shipments data presented in Appendix C, were obtained from Form EIA-7A, ''Coal Production Report,'' from companies owning mining operations that produced, processed, or prepared 10,000 or more short tons of coal in 1984. These mining operations accounted for 99.4% of total US coal production and represented 76.3% of all US coal mining operations in 1984. This report also includes data for the demonstrated reserve base of coal in the United States on January 1, 1984.

Emissions of airborne toxics from coal-fired boilers: Mercury  

SciTech Connect (OSTI)

Concerns over emissions of hazardous air Pollutants (air toxics) have emerged as a major environmental issue, and the authority of the US Environmental Protection Agency to regulate such pollutants was greatly expanded through the Clean Air Act Amendments of 1990. Mercury has been singled out for particular attention because of concerns over possible effects of emissions on human health. This report evaluates available published information on the mercury content of coals mined in the United States, on mercury emitted in coal combustion, and on the efficacy of various environmental control technologies for controlling airborne emissions. Anthracite and bituminous coals have the highest mean-mercury concentrations, with subbituminous coals having the lowest. However, all coal types show very significant variations in mercury concentrations. Mercury emissions from coal combustion are not well-characterized, particularly with regard to determination of specific mercury compounds. Variations in emission rates of more than an order of magnitude have been reported for some boiler types. Data on the capture of mercury by environmental control technologies are available primarily for systems with electrostatic precipitators, where removals of approximately 20% to over 50% have been reported. Reported removals for wet flue-gas-desulfurization systems range between 35 and 95%, while spray-dryer/fabric-filter systems have given removals of 75 to 99% on municipal incinerators. In all cases, better data are needed before any definitive judgments can be made. This report briefly reviews several areas of research that may lead to improvements in mercury control for existing flue-gas-clean-up technologies and summarizes the status of techniques for measuring mercury emissions from combustion sources.

Coal extraction  

SciTech Connect (OSTI)

Coal is extracted using a mixed solvent which includes a substantially aromatic component and a substantially naphthenic component, at a temperature of 400/sup 0/ to 500/sup 0/C. Although neither component is an especially good solvent for coal by itself, the use of mixed solvent gives greater flexibility to the process and offers efficiency gains.

Coal availability and coal recoverability studies: A reevaluation of the United States coal resources  

SciTech Connect (OSTI)

A cooperative program between the US Geological Survey (USGS), US Bureau of Mines (USBM), and geological agencies of the principal coal-bearing States has began to (1) identify and delineate current major land-use/environmental and technologic/geologic restrictions on the availability of coal resources; (2) estimate the amount of remaining coal resources that may be available for development under those constraints; (3) estimate the amount that can be economically extracted and marketed; and (4) identify possible social and economic disruptions that could occur within local and regional economies as coal resources are exhausted. Within major coal-producing regions, selected 7.5-minute quadrangles are chosen to represent variations in geology, topography, and land-use patterns so that results might be extrapolated throughout the entire region. After identifying State and Federal coal mining regulations, USGS and State scientists consult with local coal-industry engineers, geologists, and mine operators to ascertain local mining practices. Coal bed outcrop lines, current and past mined areas, and restrictions to mining are plotted at 1:24,000 scale and geographic information system (GIS) techniques are applied. Coal availability/recoverability studies have expanded into the central and northern Appalachian regions, Illinois basin, and Powder River basin. The first four basins, with 75% of current US coal production, should be completed by 1998. The total program is designed to cover 150 quadrangles from within the 11 major coal regions of the US. These 11 regions represent 97% of current US coal production. Planned project completion is 2001.

China's Coal: Demand, Constraints, and Externalities  

SciTech Connect (OSTI)

This study analyzes China's coal industry by focusing on four related areas. First, data are reviewed to identify the major drivers of historical and future coal demand. Second, resource constraints and transport bottlenecks are analyzed to evaluate demand and growth scenarios. The third area assesses the physical requirements of substituting coal demand growth with other primary energy forms. Finally, the study examines the carbon- and environmental implications of China's past and future coal consumption. There are three sections that address these areas by identifying particular characteristics of China's coal industry, quantifying factors driving demand, and analyzing supply scenarios: (1) reviews the range of Chinese and international estimates of remaining coal reserves and resources as well as key characteristics of China's coal industry including historical production, resource requirements, and prices; (2) quantifies the largest drivers of coal usage to produce a bottom-up reference projection of 2025 coal demand; and (3) analyzes coal supply constraints, substitution options, and environmental externalities. Finally, the last section presents conclusions on the role of coal in China's ongoing energy and economic development. China has been, is, and will continue to be a coal-powered economy. In 2007 Chinese coal production contained more energy than total Middle Eastern oil production. The rapid growth of coal demand after 2001 created supply strains and bottlenecks that raise questions about sustainability. Urbanization, heavy industrial growth, and increasing per-capita income are the primary interrelated drivers of rising coal usage. In 2007, the power sector, iron and steel, and cement production accounted for 66% of coal consumption. Power generation is becoming more efficient, but even extensive roll-out of the highest efficiency units would save only 14% of projected 2025 coal demand for the power sector. A new wedge of future coal consumption is likely to come from the burgeoning coal-liquefaction and chemicals industries. If coal to chemicals capacity reaches 70 million tonnes and coal-to-liquids capacity reaches 60 million tonnes, coal feedstock requirements would add an additional 450 million tonnes by 2025. Even with more efficient growth among these drivers, China's annual coal demand is expected to reach 3.9 to 4.3 billion tonnes by 2025. Central government support for nuclear and renewable energy has not reversed China's growing dependence on coal for primary energy. Substitution is a matter of scale: offsetting one year of recent coal demand growth of 200 million tonnes would require 107 billion cubic meters of natural gas (compared to 2007 growth of 13 BCM), 48 GW of nuclear (compared to 2007 growth of 2 GW), or 86 GW of hydropower capacity (compared to 2007 growth of 16 GW). Ongoing dependence on coal reduces China's ability to mitigate carbon dioxide emissions growth. If coal demand remains on a high growth path, carbon dioxide emissions from coal combustion alone would exceed total US energy-related carbon emissions by 2010. Within China's coal-dominated energy system, domestic transportation has emerged as the largest bottleneck for coal industry growth and is likely to remain a constraint to further expansion. China has a low proportion of high-quality reserves, but is producing its best coal first. Declining quality will further strain production and transport capacity. Furthermore, transporting coal to users has overloaded the train system and dramatically increased truck use, raising transportation oil demand. Growing international imports have helped to offset domestic transport bottlenecks. In the long term, import demand is likely to exceed 200 million tonnes by 2025, significantly impacting regional markets.

Northern Alaska-Slope, Central Alaska-Nenana, and Southern Alaska-Cook Inlet. Cretaceous resources, predominantly bituminous coal and lignite, are in the Northern Alaska-Slope coal province. Most of the Tertiary resources, mainly lignite to subbituminous coal with minor amounts of bituminous and semianthracite coals, are in the other two provinces. The combined measured, indicated, inferred, and hypothetical coal resources in the three areas are estimated to be 5,526 billion short tons (5,012 billion metric tons), which constitutes about 87 percent of Alaska's coal and surpasses the total coal resources of the conterminous United States by 40 percent.

Coal surface control for advanced fine coal flotation  

SciTech Connect (OSTI)

The primary objective of this research project is to develop advanced flotation methods for coal cleaning in order to achieve near total pyritic-sulfur removal at 90% Btu recovery, using coal samples procured from six major US coal seams. Concomitantly, the ash content of these coals is to be reduced to 6% or less. Work this quarter concentrated on the following: washability studies, which included particle size distribution of the washability samples, and chemical analysis of washability test samples; characterization studies of induction time measurements, correlation between yield, combustible-material recovery (CMR), and heating-value recovery (HVR), and QA/QC for standard flotation tests and coal analyses; surface modification and control including testing of surface-modifying reagents, restoration of hydrophobicity to lab-oxidized coals, pH effects on coal flotation, and depression of pyritic sulfur in which pyrite depression with calcium cyanide and pyrite depression with xanthated reagents was investigated; flotation optimization and circuitry included staged reagent addition, cleaning and scavenging, and scavenging and middling recycling. Weathering studies are also discussed. 19 figs., 28 tabs.

Chemical structure of coal tar during devolatilization  

SciTech Connect (OSTI)

Enormous progress has been made in coal pyrolysis research during the last two decades. Models of coal devolatilization have progressed from simple rate expressions based on total mass release to empirical relationships based on the elemental composition of the parent coal to models that attempt to describe the macromolecular network of the coal. In the last several years, advancements in chemical analysis techniques have allowed quantitative investigations of the chemical structure of both coal and its pyrolysis products, including the nature of the resulting char. A prominent research goal is to accurately predict the rates, yields, and products of devolatilization from measurements of the parent coal structure. The prediction of nitrogen species evolved during devolatilization is of current interest. These goals necessitate modeling the reaction processes on the molecular scale, with activation energies that relate to chemical bond breaking rather than to the mass of products released from the coal. Solid-state {sup 13}C NMR spectroscopy has proven particularly useful in obtaining average values of chemical structure features of coal and char, while liquid phase {sup 1}H NMR spectroscopy has been used to determine some of the chemical features of coal tar. Pyridine extract residues from coal and partially-pyrolyzed coal chars have also been analyzed by solid-state {sup 13}C NMR spectroscopy, and the extracts have been analyzed by {sup 1}H NMR spectroscopy.

China's Present Situation of Coal Consumption and Future Coal Demand Forecast  

Science Journals Connector (OSTI)

This article analyzes China's coal consumption changes since 1991 and proportion change of coal consumption to total energy consumption. It is argued that power, iron and steel, construction material, and chemical industries are the four major coal consumption industries, which account for 85% of total coal consumption in 2005. Considering energy consumption composition characteristics of these four industries, major coal demand determinants, potentials of future energy efficiency improvement, and structural changes, etc., this article makes a forecast of 2010s and 2020s domestic coal demand in these four industries. In addition, considering such relevant factors as our country's future economic growth rate and energy saving target, it forecasts future energy demands, using per unit GDP energy consumption method and energy elasticity coefficient method as well. Then it uses other institution's results about future primary energy demand, excluding primary coal demand, for reference, and forecasts coal demands in 2010 and 2020 indirectly. After results comparison between these two methods, it is believed that coal demands in 2010 might be 2620–2850 million tons and in 2020 might be 3090–3490 million tons, in which, coal used in power generation is still the driven force of coal demand growth.

Coal preparation: The essential clean coal technology  

SciTech Connect (OSTI)

This chapter is a brief introduction to a broad topic which has many highly specialized areas. The aim is to summarize the essential elements of coal preparation and illustrate its important role in facilitating the clean use of coal. Conventional coal preparation is the essential first step in ensuring the economic and environmentally acceptable use of coal. The aim of coal preparation is to produce saleable products of consistent, specified quality which satisfy customer requirements while optimizing the utilization of the coal resource. Coal preparation covers all aspects of preparing coal for the market. It includes size reduction, blending and homogenization and, most importantly, the process of physical beneficiation or washing, which involves separation of undesirable mineral matter from the coal substance itself. Coal preparation can be performed at different levels of sophistication and cost. The degree of coal preparation required is decided by considering the quality of the raw coal, transport costs and, in particular, the coal quality specified by the consumer. However, the cost of coal beneficiation rises rapidly with the complexity of the process and some coal is lost with the waste matter because of process inefficiencies, therefore each situation requires individual study to determine the optimum coal preparation strategy. The necessary expertise is available within APEC countries such as Australia. Coals destined for iron making are almost always highly beneficiated. Physical beneficiation is mostly confined to the higher rank, hard coals, but all other aspects of coal preparation can be applied to subbituminous and lignitic coals to improve their utilization. Also, there are some interesting developments aimed specifically at reducing the water content of lower rank coals.

Chapter 18 - Worldwide Coal Mine Methane and Coalbed Methane Activities  

Science Journals Connector (OSTI)

Abstract The chapter provides an overview of coal bed methane production in all countries (except USA; covered in Chapter 17) around the world where there is a viable coal deposit. Coal deposits are shown in a map and coal bed methane reserves are estimated. All countries can follow the lead provided by USA in CBM production where 10% of total gas consumption (2 TCF/year) comes from coal seams. Exploitation of thick and deep coal seams using the latest technology can create a vast source of domestic energy for many countries around the world.

Annual Energy Outlook 2006 with Projections to 2030 - Coal  

Gasoline and Diesel Fuel Update (EIA)

Coal Coal Annual Energy Outlook 2006 with Projections to 2030 Market Share of Western Coal Continues To Increase U.S. coal production has remained near 1,100 million tons annually since 1996. In the AEO2006 reference case, increasing coal use for electricity generation at existing plants and construction of a few new coal-fired plants lead to annual production increases that average 1.1 percent per year from 2004 to 2015, when total production is 1,272 million tons. The growth in coal production is even stronger thereafter, averaging 2.0 percent per year from 2015 to 2030, as substantial amounts of new coal-fired generating capacity are added, and several CTL plants are brought on line.

Alaska coal geology, resources, and coalbed methane potential  

SciTech Connect (OSTI)

Estimated Alaska coal resources are largely in Cretaceous and Tertiary rocks distributed in three major provinces, Northern Alaska-Slope, Central Alaska-Nenana, and Southern Alaska-Cook Inlet. Cretaceous resources, predominantly bituminous coal and lignite, are in the Northern Alaska-Slope coal province. Most of the Tertiary resources, mainly lignite to subbituminous coal with minor amounts of bituminous and semianthracite coals, are in the other two provinces. The combined measured, indicated, inferred, and hypothetical coal resources in the three areas are estimated to be 5,526 billion short tons (5,012 billion metric tons), which constitutes about 87 percent of Alaska's coal and surpasses the total coal resources of the conterminous United States by 40 percent. Coal mining has been intermittent in the Central Alaskan-Nenana and Southern Alaska-Cook Inlet coal provinces, with only a small fraction of the identified coal resource having been produced from some dozen underground and strip mines. Alaskan coals have a lower sulfur content (averaging 0.3 percent) than most coals in the conterminous United States and are within or below the minimum sulfur value mandated by the 1990 Clean Air Act amendments. Another untapped potential resource is coalbed methane estimated to total 1,000 trillion cubic feet (28 trillion cubic meters).

X-ray Computed Tomography of coal: Final report  

SciTech Connect (OSTI)

X-ray Computed Tomography (CT) is a method of mapping with x-rays the internal structures of coal. The technique normally produces 2-D images of the internal structures of an object. These images can be recast to create pseudo 3-D representations. CT of coal has been explored for a variety of different applications to coal and coal processing technology. In a comparison of CT data with conventional coal analyses and petrography, CT was found to offer a good indication of the total ash content of the coal. The spatial distribution of the coal mineral matter as seen with CT has been suggested as an indicator of coal washability. Studies of gas flow through coal using xenon gas as a tracer have shown the extremely complicated nature of the modes of penetration of gas through coal, with significant differences in the rates at which the gas can pass along and across the bedding planes of coal. In a special furnace designed to allow CT images to be taken while the coal was being heated, the pyrolysis and gasification of coal have been studied. Gasification rates with steam and CO/sub 2/ for a range of coal ranks have been obtained, and the location of the gasification reactions within the piece of coal can be seen. Coal drying and the progress of the pyrolysis wave into coal have been examined when the coal was subjected to the kind of sudden temperature jump that it might experience in fixed bed gasifier applications. CT has also been used to examine stable flow structures within model fluidized beds and the accessibility of lump coal to microbial desulfurization. 53 refs., 242 figs., 26 tabs.

Clean coal  

SciTech Connect (OSTI)

The article describes the physics-based techniques that are helping in clean coal conversion processes. The major challenge is to find a cost- effective way to remove carbon dioxide from the flue gas of power plants. One industrially proven method is to dissolve CO{sub 2} in the solvent monoethanolamine (MEA) at a temperature of 38{sup o}C and then release it from the solvent in another unit when heated to 150{sup o}C. This produces CO{sub 2} ready for sequestration. Research is in progress with alternative solvents that require less energy. Another technique is to use enriched oxygen in place of air in the combustion process which produces CO{sub 2} ready for sequestration. A process that is more attractive from an energy management viewpoint is to gasify coal so that it is partially oxidized, producing a fuel while consuming significantly less oxygen. Several IGCC schemes are in operation which produce syngas for use as a feedstock, in addition to electricity and hydrogen. These schemes are costly as they require an air separation unit. Novel approaches to coal gasification based on 'membrane separation' or chemical looping could reduce the costs significantly while effectively capturing carbon dioxide. 1 ref., 2 figs., 1 photo.

Coal: evolving supply and demand in world seaborne steam coal trade. [1975 to 1985; forecasting to 1995  

SciTech Connect (OSTI)

This paper describes the evolution of world seaborne steam coal trade since 1975. It highlights current trends and the historic and present sources of supply and demand and discusses selected factors that may affect future world trade patterns. It concludes with a general discussion on the prospects for United States participation in the growing world markets for steam coal. Worldwide seaborne steam coal trade is linked very closely to the generation of electricity and industrial use of process heat in cement and other manufacturing plants. The main factors that influence this trade are: economic growth, electricity demand, indigenous coal production (and degree of protection from lower cost coal imports), and the delivered costs of coal relative to other substitutable fuels. It may be of interest to know how these factors have changed seaborne steam coal trade in the past twelve years. In 1970, the total world use of steam coal was about two billion short tons. International trade in steam coal was only 80 million tons or about 4% of the total. Seaborne trade accounted for about 30% of international trade, or about 25 million tons. In 1982, the latest year for which good statistics are available, total world use of steam coal was about 3.6 billion tons. Seaborne steam coal trade was 110 million tons which is about 3% of the total and 37% of the international trade. 11 figs., 2 tabs.

Since many of the pollutants that formed "acid rain" were coming from big coal-burning power plants in the United States, the U.S. Government took the lead in finding a solution. One of the steps taken by the U.S. Department of Energy was to create a partnership program between the Government, several States, and private companies to test new methods developed by scientists to make coal burning much cleaner. This became the "Clean Coal Technology Program."

Environmental and economic challenges to coal`s future in China  

SciTech Connect (OSTI)

Coal accounts for approximately 75% of China`s total primary energy consumption, and is by far the largest contributor to air pollution. The highest growth sector for coal consumption is the power sector, accounting for about 36 percent of total coal consumption in 1993. Over the 1994--2010 period most new, large power plants are expected to be coal-fired. Therefore, the availability and price of coal, as well as environmental constraints will be critical to foreign investors evaluating coal and power projects in China. The purpose of this paper is to provide useful technical, economic and environmental information and analysis on coal and the power sectors of China. The target audiences are potential investors and government energy and environmental policy people. This paper suggests a number of important energy and environmental policy issues that need to be addressed in a timely fashion in order to promote adequate levels of investment in coal and power developments in China. Although this paper highlights problems faced by foreign investors in coal and power, it is important to balance these problems against the large investment opportunities developing in these sectors.

Characteristics of airborne coal mine dust and its implication to coal workers' pneumoconiosis  

SciTech Connect (OSTI)

Size selective airborne dust samples were collected using 4-stage cassette impactors at nine different locations in continuous mining sections in each of five coal seams located in the Appalachian bituminous coal field. These coal seams were the Upper Freeport, Pittsburgh, Kittanning, Coalburg, and Pocahontas. Mineralogical analyses were performed by an x-ray powder diffraction photographic technique. The distributions of total and respirable dust concentrations were fit best by a log-normal distribution. The effects of the coal seam and the sampling location on dust levels were significant. The results of the particle size distribution analyses suggest that coal mine dust has a multi-modal distribution. The effects of the coal seam and the sampling locations were significant. The distributions obtained were often affected by such mine-related variables as ventilation rate, relative humidity, and the section dimensions. Nine minerals commonly found in the coal mine dust samples collected from the coal seams studied were illite, calcite, kaolinite, quartz, dolomite, siderite, gypsum, anhydrite, and pyrite in descending order of magnitude. Relative abundance of all mineral species except siderite and gypsum was coal seam specific and suggests that existence of coal seam variability of mineral content. Although mineral content was affected by sampling locations and the sections within a mine, the magnitude was small when compared with that of cal seams. Mineral content also appears to be affected by particle size, although no particular pattern was observed.

Chapter 14 - Coal bed methane  

Science Journals Connector (OSTI)

Publisher Summary Methane adsorbed to the surface of coal is a very old issue with some new commercial ramifications. This explosive gas has made underground coal mines dangerous both from the risk of explosion and the possibility of an oxygen-poor atmosphere that wouldn't support life. The miner's main concern with coal bed methane (CBM) has been how to get rid of it. Techniques to deal with CBM in mines have ranged from the classic canary in a cage to detect an oxygen-poor atmosphere to huge ventilation fans to force the replacement of a methane-rich environment with outside air, to drilling CBM wells in front of the coal face to try to degas the coal prior to exposing the mine to the CBM. All these techniques have met with some amount of success. None of the techniques to prevent CBM from fouling the air in an underground mine has been totally successful. With the CBM's unique method of gas storage, the preponderance of the gas is available only to very low coalface pressures. The coalface pressure is set by a combination of flowing wellhead pressure and the hydrostatic head exerted by standing liquid within the well bore. Effective compression strategies can lower the wellhead pressure to very low values. Effective deliquification techniques can reduce or remove the backpressure caused by accumulated liquid. CBM's economic impact is briefly explained in this chapter.

A "Bed" for Burning Coal A "Bed" for Burning Coal Clean Coal 101 Lesson 4: A "Bed" for Burning Coal? It was a wet, chilly day in Washington DC in 1979 when a few scientists and engineers joined with government and college officials on the campus of Georgetown University to celebrate the completion of one of the world's most advanced coal combustors. It was a small coal burner by today's standards, but large enough to provide heat and steam for much of the university campus. But the new boiler built beside the campus tennis courts was unlike most other boilers in the world. A Fluidized Bed Boiler A Fluidized Bed Boiler In a fluidized bed boiler, upward blowing jets of air suspend burning coal, allowing it to mix with limestone that absorbs sulfur pollutants.

Investigations into coal coprocessing and coal liquefaction  

SciTech Connect (OSTI)

The conversion of coal to liquid suitable as feedstock to a petroleum refinery is dependent upon several process variables. These variables include temperature, pressure, coal rank, catalyst type, nature of the feed to the reactor, type of process, etc. Western Research Institute (WRI) has initiated a research program in the area of coal liquefaction to address the impact of some of these variables upon the yield and quality of the coal-derived liquid. The principal goal of this research is to improve the efficiency of the coal liquefaction process. Two different approaches are currently being investigated. These include the coprocessing of a heavy liquid, such as crude oil, and coal using a dispersed catalyst and the direct liquefaction of coal using a supported catalyst. Another important consideration in coal liquefaction is the utilization of hydrogen, including both externally- and internally-supplied hydrogen. Because the incorporation of externally-supplied hydrogen during conversion of this very aromatic fossil fuel to, for example, transportation fuels is very expensive, improved utilization of internally-supplied hydrogen can lead to reducing processing costs. The objectives of this investigation, which is Task 3.3.4, Coal Coprocessing, of the 1991--1992 Annual Research Plan, are: (1) to evaluate coal/oil pretreatment conditions that are expected to improve the liquid yield through more efficient dispersion of an oil-soluble, iron-based catalyst, (2) to characterize the coke deposits on novel, supported catalysts after coal liquefaction experiments and to correlate the carbon skeletal structure parameters of the coke deposit with catalyst performance as measured by coal liquefaction product yield, and (3) to determine the modes of hydrogen utilization during coal liquefaction and coprocessing. Experimental results are discussed in this report.

Upgraded Coal Interest Group  

SciTech Connect (OSTI)

The Upgraded Coal Interest Group (UCIG) is an EPRI 'users group' that focuses on clean, low-cost options for coal-based power generation. The UCIG covers topics that involve (1) pre-combustion processes, (2) co-firing systems and fuels, and (3) reburn using coal-derived or biomass-derived fuels. The UCIG mission is to preserve and expand the economic use of coal for energy. By reducing the fuel costs and environmental impacts of coal-fired power generation, existing units become more cost effective and thus new units utilizing advanced combustion technologies are more likely to be coal-fired.

Low-Btu coal gasification in the United States: company topical. [Brick producers  

SciTech Connect (OSTI)

Hazelton and other brick producers have proved the reliability of the commercial size Wellman-Galusha gasifier. For this energy intensive business, gas cost is the major portion of the product cost. Costs required Webster/Hazelton to go back to the old, reliable alternative energy of low Btu gasification when the natural gas supply started to be curtailed and prices escalated. Although anthracite coal prices have skyrocketed from $34/ton (1979) to over $71.50/ton (1981) because of high demand (local as well as export) and rising labor costs, the delivered natural gas cost, which reached $3.90 to 4.20/million Btu in the Hazelton area during 1981, has allowed the producer gas from the gasifier at Webster Brick to remain competitive. The low Btu gas cost (at the escalated coal price) is estimated to be $4/million Btu. In addition to producing gas that is cost competitive with natural gas at the Webster Brick Hazelton plant, Webster has the security of knowing that its gas supply will be constant. Improvements in brick business and projected deregulation of the natural gas price may yield additional, attractive cost benefits to Webster Brick through the use of low Btu gas from these gasifiers. Also, use of hot raw gas (that requires no tar or sulfur removal) keeps the overall process efficiency high. 25 references, 47 figures, 14 tables.

Hazard recognition and adjustment in northern Appalachia: examples of coal-mine subsidence in small communities  

SciTech Connect (OSTI)

Mine subsidence is a pervasive hazard in the northern Appalachian coal fields and is associated with both active and abandoned mines. Causative factors include the method of mining, geological and hydrologic conditions, and surface activities. Its economic costs include surface property damages and depreciations plus costs of mitigation. Environmental impacts include derangement of surface drainage and loss of aquifer. These topics are reviewed here, and on subsidence cognition and the research findings are discussed. One bituminous and three anthracite area boroughs in Pennsylvania served as case studies. Local officials and planners were informally interviewed and surveys of residents conducted. The present study differs from most in the traditional hazard-perception genus in several ways. It addresses the salience of hazard amid other pressing community concerns. Salience, rather than perceived seriousness, provides greater insights into residents' coping responses. Consideration is given to institutional and other contextual influences on individuals' adjustment strategies. Finally, coal mine subsidence is a technological hazard, albeit one which is geological in character.

Modernization of Ohio's coal reserves, Phase 1  

SciTech Connect (OSTI)

The objectives of this project were to determine state-level totals of the estimated economic resource, minable reserve base, and recoverable coal in Ohio, allocated to specified ranges of sulfur and heat content. In addition, resources and reserves were to be categorized by mining methods (surface and underground). Land use and environmental restrictions, needed to determine remaining minable reserves, were to be delineated and percentages of restricted coal calculated. In context of a Phase 1, one-year project, the objectives of this project were to update Ohio's coal reserves and resources for as many counties as time allowed, and to deplete production tonnages to January 1, 1991, on the remaining coal-producing counties. For the depleted counties, only estimated economic resources were required or possible with the data available. 24 refs., 9 figs., 3 tabs.

An efficient process for recovery of fine coal from tailings of coal washing plants  

SciTech Connect (OSTI)

Gravity concentration of hard lignites using conventional jigs and heavy media separation equipment is prone to produce coal-rich fine tailings. This study aims to establish a fine coal recovery process of very high efficiency at reasonable capital investment and operational costs. The technical feasibility to upgrade the properties of the predeslimed fine refuse of a lignite washing plant with 35.9% ash content was investigated by employing gravity separation methods. The laboratory tests carried out with the combination of shaking table and Mozley multi-gravity separator (MGS) revealed that the clean coal with 18% ash content on dry basis could be obtained with 58.9% clean coal recovery by the shaking table stage and 4.1% clean coal recovery by MGS stage, totaling to the sum of 63.0% clean coal recovery from a predeslimed feed. The combustible recovery and the organic efficiency of the shaking table + MGS combination were 79.5% and 95.5%, respectively. Based on the results of the study, a flow sheet of a high-efficiency fine coal recovery process was proposed, which is also applicable to the coal refuse pond slurry of a lignite washing plant.

Bio-coal briquette  

SciTech Connect (OSTI)

Some of the developing nations aim to earn foreign currency by exporting oil and/or gas and to increase the domestic consumption of coal to ensure a secure energy supply. Therefore, it is very important to promote effective coal utilization in these nations. Currently, these countries experience problems associated with coal use for household cooking and household industries. For household cooking, coal creates too much smoke and smells unpleasant. In addition, illegally obtained firewood is almost free in local agricultural regions. Coal is also used in household industries; however, simple stoker boilers are inefficient, since unburned coal particles tend to drop through screens during the combustion process. The bio-coal briquette, on the other hand, is an effective and efficient fuel, since it utilizes coal, which is to be used extensively in households and in small and medium-scale industry sectors in some coal-producing countries, as a primary fuel and bamboos (agricultural waste) as a secondary fuel. In addition, the use of bio-coal briquettes will greatly help reduce unburned coal content.

Chemical comminution of coal  

SciTech Connect (OSTI)

The objective of the present research is to study the chemical reactivity of a mixture of methyl alcohol and aqueous sodium hydroxide solution in the temperature range 298 to 363 K, and a caustic concentration of 0 to 10 wt. %, on an Iowa bituminous coal. The sample studied was collected from coal zone 4, equivalent to most historical references to Laddsdale coal. The coals in this zone are typical high-sulfur, high-ash middle Pennsylvania Cherokee group coals. The apparent rank is high-volatile C bituminous coal. The relatively high content of sulfur and 23 other elements in these coals is related to near neutral (6-8) pH conditions in the depositional and early diagenetic environments, and to postdepositional sphalerite/calcite/pyrite/kaolinite/barite mineralization.

Coal dust explosibility  

Science Journals Connector (OSTI)

This paper reports US Bureau of Mines (USBM) research on the explosibility of coal dusts. The purpose of this work is to improve safety in mining and other industries that process or use coal. Most of the tests were conducted in the USBM 20 litre laboratory explosibility chamber. The laboratory data show relatively good agreement with those from full-scale experimental mine tests. The parameters measured included minimum explosible concentrations, maximum explosion pressures, maximum rates of pressure rise, minimum oxygen concentrations, and amounts of limestone rock dust required to inert the coals. The effects of coal volatility and particle size were evaluated, and particle size was determined to be at least as important as volatility in determining the explosion hazard. For all coals tested, the finest sizes were the most hazardous. The coal dust explosibility data are compared to those of other hydrocarbons, such as polyethylene dust and methane gas, in an attempt to understand better the basics of coal combustion.

Coal: the new black  

SciTech Connect (OSTI)

Long eclipsed by oil and natural gas as a raw material for high-volume chemicals, coal is making a comeback, with oil priced at more than $100 per barrel. It is relatively cheap feedstock for chemicals such as methanol and China is building plants to convert coal to polyolefins on a large scale and interest is spreading worldwide. Over the years several companies in the US and China have made fertilizers via the gasification of coal. Eastman in Tennessee gasifies coal to make methanol which is then converted to acetic acid, acetic anhydride and acetate fiber. The future vision is to convert methanol to olefins. UOP and Lurgi are the major vendors of this technology. These companies are the respective chemical engineering arms of Honeywell and Air Liquide.

Alcohol flushing for enhanced removal of coal tar from contaminated soils  

SciTech Connect (OSTI)

Alcohol flushing for enhancing the removal of coal tar from contaminated soils and reducing coal tar concentrations in the aqueous-phase leachate was investigated. Four soil columns were packed with relatively undisturbed coal tar contaminated soils collected from a former coal gasification site. These columns were leached with water and then flushed with isopropyl alcohol (IPA) solutions. Initially, total coal tar concentrations in water leachate ranged from = 0.1 to 150 mg/L for the four columns. Coal tar concentrations in the column effluent generally increased three to five orders of magnitude during the initial IPA flush. Each column was flushed with 1-3 pore volumes of an IPA solution. Reduction of coal tar concentrations in water leachate, attributed to the alcohol flushing, was noted in three of the four columns. The total coal tar removed from the soil columns during the IPA flushes constituted from 54 to 97% of the total coal tar removed during both water leaching (240-800 pore volumes) and alcohol flushing (1-3 pore volumes). The alcohol flushing removed from 3 to 19 % of the total coal tar in the various soil columns. Results indicated that alcohol flushing can enhance the removal of coal tar from contaminated soils and can reduce the aqueous-phase coal tar concentrations in the leachate. 16 refs., 5 figs., 3 tabs.

Ultrasound-promoted chemical desulfurization of Illinois coals  

SciTech Connect (OSTI)

The overall objectives of the program were to investigate the use of ultrasound to promote coal desulfurization reactions and to evaluate chemical coal desulfurization schemes under mild conditions through a fundamental understanding of their reaction mechanisms and kinetics. The ultimate goal was to develop an economically feasible mild chemical process to reduce the total sulfur content of Illinois Basin Coals, while retaining their original physical characteristics, such as calorific value and volatile matter content. During the program, potential chemical reactions with coal were surveyed under various ultrasonic irradiation conditions for desulfurization, to formulate preliminary reaction pathways, and to select a few of the more promising chemical processes for more extensive study.

Chapter 2 - Coal as Multiple Sources of Energy  

Science Journals Connector (OSTI)

Abstract Coal as multiple sources of energy is mined for its solid and gas-, oil-, and condensate-derived hydrocarbons as well as liquefied for synfuels. More than 50 countries mine coal as feedstock for power plants to generate electricity but only six of these countries monopolize 73% of the total recoverable coalbed gas resources of the world. Worldwide, about 30,000 coal mine explosions are caused by methane and carbon dioxide, and to prevent outbursts and emissions, underground, surface, and abandoned coalmine gases are exploited for industrial and commercial uses. Still, a large volume of unrecovered fugitive coalmine gases is released as global greenhouse gas emissions. An alternative source for foreign oil dependent countries is synfuels from coal liquefaction technology. Also, coal-derived hydrocarbons are a part of the conventional resources that is, gas, oil, and condensate sourced from coal but expelled into adjoining reservoirs, are attractive alternative energy sources.

Coal Storage and Transportation  

Science Journals Connector (OSTI)

Abstract Coal preparation, storage, and transportation are essential to coal use. Preparation plants, located near to the mine, remove some inorganic minerals associated with raw coal. Coal is transported from the mines to the point of consumption, often an electric generating plant, by rail, barge and trucks. Railroads are the predominant form of coal transportation within a country. Global coal trade, movement by large ocean-going vessels, continues to increase. At the end use site, the coal is crushed, ground, and the moisture content reduced to the proper specifications for end use. Coal is stored at various points in the supply chain. Processed coal will weather and oxidize, changing its properties; it can self-ignite, unless precautions are taken. Technology in use today is similar to that used in previous decades. Performance improvements have come from improved software and instruments that deliver real-time data. These improve management of sub-processes in the coal supply chain and reduce costs along the supply chain.

Coal surface control for advanced physical fine coal cleaning technologies. Final report, September 19, 1988--August 31, 1992  

SciTech Connect (OSTI)

This final report presents the research work carried out on the Coal Surface Control for Advanced Physical Fine Coal Cleaning Technologies project, sponsored by the US Department of Energy, Pittsburgh Energy Technology Center (DOE/PETC). The project was to support the engineering development of the selective agglomeration technology in order to reduce the sulfur content of US coals for controlling SO{sub 2} emissions (i.e., acid rain precursors). The overall effort was a part of the DOE/PETCs Acid Rain Control Initiative (ARCI). The overall objective of the project is to develop techniques for coal surface control prior to the advanced physical fine coal cleaning process of selective agglomeration in order to achieve 85% pyrite sulfur rejection at an energy recovery greater than 85% based on run-of-mine coal. The surface control is meant to encompass surface modification during grinding and laboratory beneficiation testing. The project includes the following tasks: Project planning; methods for analysis of samples; development of standard beneficiation test; grinding studies; modification of particle surface; and exploratory R&D and support. The coal samples used in this project include three base coals, Upper Freeport - Indiana County, PA, Pittsburgh NO. 8 - Belmont County, OH, and Illinois No. 6 - Randolph County, IL, and three additional coals, Upper Freeport - Grant County- WV, Kentucky No. 9 Hopkins County, KY, and Wyodak - Campbell County, WY. A total of 149 drums of coal were received.

METC research on coal-fired diesels  

SciTech Connect (OSTI)

The METC in-house Coal-Fueled Diesel Research project is part of the overall DOE effort to develop a technology base for diesel engines capable of operating on coal, shale oil or low-cost coal-derived fuels. The in-house effort started in 1985 as a test-bed for coal-derived liquid fuels and will end this fiscal year with the successful completion of METC`s diesel R&D program. Currently METC in-house research and development efforts focus on pilot chamber combustion in METC`s coal-water slurry (CWS) fueled diesel engine. A novel pilot chamber for a direct-injected, coal-fueled diesel engine has been designed and is being tested in METC`s single cylinder research diesel engine. The pilot chamber configuration allows for operation at extended load and speed conditions using 100 percent CWS and no other pilot fuel. The concept involves the use of a small volume chamber exterior to the main cylinder in which approximately 5 percent of the total fuel energy at full load conditions is injected. Lower NO{sub X} levels may be obtained due to leaner burning as well as broader stable performance using only CWS fuel.

Profitability analysis of non-coking coal preparation for power plants in India  

SciTech Connect (OSTI)

Currently coal-based power plants produce about 70% of the total electricity generated in India, where non-coking (steam) coals are utilized mostly without any preparation. A massive capacity addition of at least 140,000 MWe is required (over the 81,000 MWe of current installed capacity) during the next 15 years to meet growing energy demand. Such a rapid expansion of power generation capacity poses a serious challenge to the environment (at emission controls) and transportation infrastructure in India. Furthermore, the high ash content of indigenous coals and concentration of coal mines in central and northeastern India away from urban centers exacerbate the problem. Thus, coal preparation is envisioned to play a major role in shaping the energy future of India. Under the Indo-US Coal Preparation Program, the US Department of Energy`s Pittsburgh Energy Technology Center (PETC) is coordinating coal preparation activities for the US Agency for International Development. In this context, a detailed analysis of the washability characteristics of non-coking coals was performed using the PETC Coal Preparation Plant Simulator (CPPS) to identify coal preparation strategies for India. Based on these strategies, a profitability analysis of non-coking coal preparation has been conducted considering coal preparation and transportation costs, and coal quality impacts on power plant operations. This paper summarizes the results of this analysis and quantifies the significance of coal preparation for the Indian power sector.

With clean coal technologies, there are opportunities for ensuring the sustained use of coal for a very long time. The clean coal technologies of today are already capable of reducing, if not eliminating, harmful emissions. The technologies of the future will allow coal to be burned with greatly reduced emissions, thus eliminating the necessity to treat them after they occur.

Coal liquefaction quenching process  

DOE Patents [OSTI]

There is described an improved coal liquefaction quenching process which prevents the formation of coke with a minimum reduction of thermal efficiency of the coal liquefaction process. In the process, the rapid cooling of the liquid/solid products of the coal liquefaction reaction is performed without the cooling of the associated vapor stream to thereby prevent formation of coke and the occurrence of retrograde reactions. The rapid cooling is achieved by recycling a subcooled portion of the liquid/solid mixture to the lower section of a phase separator that separates the vapor from the liquid/solid products leaving the coal reactor.

Beluga Coal Gasification - ISER  

SciTech Connect (OSTI)

ISER was requested to conduct an economic analysis of a possible 'Cook Inlet Syngas Pipeline'. The economic analysis was incorporated as section 7.4 of the larger report titled: 'Beluga Coal Gasification Feasibility Study, DOE/NETL-2006/1248, Phase 2 Final Report, October 2006, for Subtask 41817.333.01.01'. The pipeline would carry CO{sub 2} and N{sub 2}-H{sub 2} from a synthetic gas plant on the western side of Cook Inlet to Agrium's facility. The economic analysis determined that the net present value of the total capital and operating lifecycle costs for the pipeline ranges from $318 to $588 million. The greatest contributor to this spread is the cost of electricity, which ranges from $0.05 to $0.10/kWh in this analysis. The financial analysis shows that the delivery cost of gas may range from $0.33 to $0.55/Mcf in the first year depending primarily on the price for electricity.

Coal Coal Fossil Energy Study Guide: Coal Coal is the most plentiful fuel in the fossil family. The United States has more coal reserves than any other country in the world. In fact, one-fourth of all known coal in the world is in the United States, with large deposits located in 38 states. The United States has almost as much energ y in coal that can be mined as the rest of the world has in oil that can be pumped from the ground. TYPES OF COAL Coal is a black rock made up of large amounts of carbon. Like all fossil fuels, coal can be burned to release energy. Coal contains elements such as hydrogen, oxygen, and nitrogen; has various amounts of minerals; and is itself considered to be a mineral of organic origin.

Despite drop in domestic coal production, U.S. coal exports to reach Despite drop in domestic coal production, U.S. coal exports to reach record high in 2012. While U.S. coal production is down 7 percent this year due in part to utilities switching to low-priced natural gas to generate electricity, American coal is still finding plenty of buyers in overseas markets. U.S. coal exports are expected to hit a record 125 million tons in 2012, the U.S. Energy Information Administration says in its new monthly short-term energy outlook. Coal exports are expected to decline in 2013, primarily because of continuing economic weakness in Europe, lower international coal prices, and higher coal production in Asia. However, U.S. coal exports next year are still expected to top 100 million tons for the third year in a row

Figure Data This increase was largely due to two factors. First, heavy rains and flooding in Australia, Indonesia, and Colombia reduced world coal supply and forced many coal importing nations to look elsewhere, primarily to the United States, to fulfill their coal needs. In addition, the shortage of their own domestic coal in relation to growing needs, namely for China and India, provided ample opportunities for U.S. coal producers to export to these markets.

Coal in China  

SciTech Connect (OSTI)

The article gives an overview of the production and use of coal in China, for power generation and in other sectors. Coal use for power generation was 850 million tonnes in 2003 and 800 million tonnes in the non-power sector. The majority of power will continue to be produced from coal, with a trend towards new larger pulverised coal fired units and introduction of circulating fluidised bed combustors. Stricter regulations are forcing introduction of improved pollution control technologies. It seems likely that China will need international finance to supplement private and state investment to carry out a programme to develop and apply clean coal technologies. The author concludes that there is evidence of a market economy being established but there is a need to resolve inconsistencies with the planned aspects of the economy and that additional policies are needed in certain sectors to achieve sustainable development. 1 ref., 2 figs., 2 tabs.

Far- and mid-infrared spectroscopy of complex organic matter of astrochemical interest: coal, heavy petroleum fractions, and asphaltenes  

E-Print Network [OSTI]

The coexistence of a large variety of molecular species (i.e., aromatic, cycloaliphatic and aliphatic) in several astrophysical environments suggests that unidentified IR emission (UIE) occurs from small solid particles containing a mix of aromatic and aliphatic structures (e.g., coal, petroleum, etc.), renewing the astronomical interest on this type of materials. A series of heavy petroleum fractions namely DAE, RAE, BQ-1, and asphaltenes derived from BQ-1 were used together with anthracite coal and bitumen as model compounds in matching the band pattern of the emission features of proto-planetary nebulae (PPNe). All the model materials were examined in the mid-infrared (2.5-16.7 um) and for the first time in the far-infrared (16.7-200 um), and the IR bands were compared with the UIE from PPNe. The best match of the PPNe band pattern is offered by the BQ-1 heavy aromatic oil fraction and by its asphaltenes fraction. Particularly interesting is the ability of BQ-1 to match the band pattern of the aromatic-ali...

Influence of coal as an energy source on environmental pollution  

SciTech Connect (OSTI)

This article considers the influence of coal energy on environmental pollution. Coal is undoubtedly part of the greenhouse problem. The main emissions from coal combustion are sulfur dioxide (SO{sub 2}), nitrogen oxides (NOx), particulates, carbon dioxide (CO{sub 2}), and mercury (Hg). Since 1980, despite a 36% increase in electricity generation and more than a 50% increase in coal use, electric utility SO{sub 2} and NOx emissions have declined significantly. Globally, the largest source of anthropogenic greenhouse gas (GHG) emissions is CO{sub 2} from the combustion of fossil fuels - around 75% of total GHG emissions covered under the Kyoto Protocol. At the present time, coal is responsible for 30-40% of world CO{sub 2} emission from fossil fuels.

Technical support to the Solvent Refined Coal (SRC) demonstration projects: assessment of current research and development  

SciTech Connect (OSTI)

A program to demonstrate Solvent Refined Coal (SRC) technology has been initiated by the US Department of Energy (DOE) in partnership with two industrial groups. Project management responsibility has been assigned to the Oak Ridge Operations Office (ORO) of DOE. ORO requested that the Oak Ridge National Laboratory assess current research and development (R and D) activities and develop recommendations for those activities that might contribute to successful completion of the SRC demonstration plant projects. The objectives of this final report are to discuss in detail the problem areas in SRC; to discuss the current and planned R and D investigations relevant to the problems identified; and to suggest appropriate R and D activities in support of designs for the SRC demonstration plants. Four types of R and D activities are suggested: continuation of present and planned activities; coordination of activities and results, present and proposed; extension/redirection of activities not involving major equipment purchase or modifications; and new activities. Important examples of the first type of activity include continuation of fired heater, slurry rheology, and slurry mixing studies at Ft. Lewis. Among the second type of activity, coordination of data acquisition and interpretation is recommended in the areas of heat transfer, vapor/liquid equilibria, and physical properties. Principal examples of recommendations for extension/redirection include screening studies at laboratory scale on the use of carbonaceous precoat (e.g., anthracite) infiltration, and 15- to 30-day continuous tests of the Texaco gasifier at the Texaco Montebello facility (using SRC residues).

Coal combustion products (CCPs  

Broader source: Energy.gov (indexed) [DOE]

combustion products (CCPs) combustion products (CCPs) are solid materials produced when coal is burned to generate electricity. Since coal provides the largest segment of U.S. electricity generation (45 percent in 2010), finding a sustainable solution for CCPs is an important environmental challenge. When properly managed, CCPs offer society environmental and economic benefits without harm to public health and safety. Research supported by the U.S. Department of Energy's (DOE) Office of Fossil Energy (FE) has made an important contribution in this regard.

Modelling coal gasification  

Science Journals Connector (OSTI)

Coal gasification processes in a slurry-feed-type entrained-flow gasifier are studied. Novel simulation methods as well as numerical results are presented. We use the vorticity-stream function method to study the characteristics of gas flow and a scalar potential function is introduced to model the mass source terms. The random trajectory model is employed to describe the behaviour of slurry-coal droplets. Very detailed results regarding the impact of the O2/coal ratio on the distribution of velocity, temperature and concentration are obtained. Simulation results show that the methods are feasible and can be used to study a two-phase reacting flow efficiently.

Coal liquefaction process  

DOE Patents [OSTI]

A process is described for the liquefaction of coal wherein raw feed coal is dissolved in recycle solvent with a slurry containing recycle coal minerals in the presence of added hydrogen at elevated temperature and pressure. The highest boiling distillable dissolved liquid fraction is obtained from a vacuum distillation zone and is entirely recycled to extinction. Lower boiling distillable dissolved liquid is removed in vapor phase from the dissolver zone and passed without purification and essentially without reduction in pressure to a catalytic hydrogenation zone where it is converted to an essentially colorless liquid product boiling in the transportation fuel range. 1 fig.

Advanced coal technologies in Czech heat and power systems  

SciTech Connect (OSTI)

Coal is the only domestic source of fossil fuel in the Czech Republic. The coal reserves are substantial and their share in total energy use is about 60%. Presently necessary steps in making coal utilisation more friendly towards the environment have been taken and fairly well established, and an interest to develop and build advanced coal units has been observed. One IGCC system has been put into operation, and circa 10 AFBC units are in operation or under construction. Preparatory steps have been taken in building an advanced combustion unit fuelled by pulverised coal and retrofit action is taking place in many heating plants. An actual experience has shown two basic problems: (1) Different characteristic of domestic lignite, especially high content of ash, cause problems applying well-tried foreign technologies and apparently a more focused attention shall have to be paid to the quality of coal combusted. (2) Low prices of lignite (regarding energy, lignite is four times cheaper then coal) do not oblige to increase efficiency of the standing equipment applying advanced technologies. It will be of high interest to observe the effect of the effort of the European Union to establish a kind of carbon tax. It could dramatically change the existing scene in clean coal power generation by the logical pressure to increase the efficiency of energy transformation. In like manner the gradual liberalisation of energy prices might have similar consequences and it is a warranted expectation that, up to now not the best, energy balance will improve in near future.

Blackout: coal, climate and the last energy crisis  

SciTech Connect (OSTI)

Coal fuels more than 30 per cent of UK electricity production, and about 50 per cent in the US, providing a significant portion of total energy output. China and India's recent ferocious economic growth has been based almost entirely on coal-generated electricity. Coal currently looks like a solution to many of our fast-growing energy problems. However, while coal advocates are urging us full steam ahead, the increasing reliance on this dirtiest of all fossil fuels has crucial implications for energy policy, pollution levels, the global climate, world economy and geopolitics. Drawbacks to a coal-based energy strategy include: Scarcity - new studies suggest that the peak of world coal production may actually be less than two decades away; Cost - the quality of produced coal is declining, while the expense of transportation is rising, leading to spiralling costs and increasing shortages; and, Climate impacts - our ability to deal with the historic challenge of climate change may hinge on reducing coal consumption in future years.

The STB Waybill data are a sample of all rail shipments. EIA's 2011 report describes the sampling procedure. EIA aggregates the confidential STB data to three different levels: national, coal-producing basin to state, and state to state. EIA applies STB withholding rules to the aggregated data to identify records that must be suppressed to protect business-sensitive data. Also, EIA adds additional location fields to the STB data, identifying the mine from which the coal originates, the power plant that receives the coal, and, in some cases, an intermediate delivery location where coal is terminated by the initial carrier but then

Burning of coal waste piles from Douro Coalfield (Portugal): Petrological, geochemical and mineralogical characterization  

Science Journals Connector (OSTI)

In the Douro Coalfield anthracites were exploited for decades (1795–1994). Besides many small mines Douro Coalfield had two principal mining areas (S. Pedro da Cova and Pejão). Coal mining activities cause several impacts on the environment, one of which is the amount of discard or waste which was disposed of all over Douro Coalfield resulting in one of the most significant and severe impacts on the environment. Over 20 waste piles exist in the old mining areas, geographically dispersed, and three of them are presently burning. Their ignition was caused by forest fires during the summer of 2005. Samples from the burning and unburned zones of the waste piles were studied as were the gas from vents and the minerals resulting after combustion. Geochemical processes and mineralogical transformations in the burning coal waste pile were investigated. Microscopic analyses of the samples identified some particular aspects related with combustion: oxidation of pyrite, the presence of iron oxides, organic particles with cracks and rims with lowered (suppressed) Rr, devolatilization vacuoles and some char structures. The occurrence of vitreous (glassy) material as well as Fe–Al spinels in the burning coal waste provide evidences that the combustion temperature could have reached values above 1000 °C. Due to combustion, and as expected, the samples studied reported high ash yields. Samples taken from the burning zones reported an increase of As, Cr, Li, Nb, Ni, Pb, Rb, Sr and LREE concentrations and a decrease in Zr and HREE concentrations. Enrichment in Cs, Li and Rb was noted when comparing with the geochemical composition of black shales and world coals composition that is related with the contribution of granitic rocks in the sediments that originated the main lithologies of the Douro Coalfield (carbonaceous shale and lithic arenites). Cluster analyses (R-type and Q-type) were performed to understand the trend between the unburned and burning samples and it seems that some chemical variations are responsible for this separation. Elemental sulphur and salammoniac (ammonium salt) are the coal fire gas minerals neoformed on the surface of piles, near the burning zones. They were identified by different techniques, mainly SEM-EDX, XRD and FTIR. Relatively high concentrations of several aromatic compounds were detected in the gas collected at the studied areas, as well as aliphatic hydrocarbons. The highest concentrations of aromatic hydrocarbons were measured in gas samples from S. Pedro da Cova waste pile. The exposure to hazardous compounds present in the gas is a serious risk to human health and the environment.

Particulate control for low rank coals  

SciTech Connect (OSTI)

The power generating system in Victoria currently comprises a total capacity of 6650 MW. Eighty percent of this capacity consists of base load stations in the Latrobe Valley using brown coal. The Latrobe Valley brown coals have unique characteristics with high moisture content ranging from 58 percent to 70 percent and an ash content which is relatively low but very variable in nature. These and other factors associated with the coal have caused special problems in handling and combustion of the coal and the de-dusting of the boiler flue gases. In recent years, this has been the basis for the design parameters adopted for all the plants in the system. With respect to flue gas de-dusting, the SECV has carried out extensive laboratory studies to characterize the different ashes obtained from the Latrobe Valley brown coals, including precipitability and aerodynamic tests. It also carried out full-scale tests on operating plants and pilot tests have been conducted on inertial collectors, precipitators and bag filters. The Environmental Protection Authority of Victoria has established a particulate emission level of 0.150 grams/m{sup 3} n.t.p. dry for recent Latrobe Valley boilers. However, the mandated emission level takes into account wide variations in operating conditions, and the plants normally achieve much lower emission levels. The Latrobe Valley plants presently in operation include Yallourn W (2x350 MW + 2x375 MW), Morwell (170 MW total and briquette factory), Hazelwood (8x200 MW) and Loy Yang (4x500 MW). The Yalloum W boilers are supplied with coal from the Yalloum Open Cut, the Morwell and Hazelwood boilers from the Morwell Open Cut and Loy Yang boilers from the Loy Yang Open Cut. All boilers are pulverized coal fired (PCF) and incorporate special firing equipment to enable the as-mined wet coal to be fired directly into the furnaces. All boilers are fitted with electrostatic precipitators. The locations of the stations and open cuts are shown.

The goal of the U.S. Department of Energy's (DOE) Clean Coal Technology (CCT) Program is to provide the energy marketplace with advanced, more efficient, and environmentally responsible coal utilization options by conducting demonstrations of new technologies. These demonstration projects are intended to establish the commercial feasibility of promising advanced coal technologies that have been developed to a level at which they are ready for demonstration testing under commercial conditions. This document serves as a DOE post-project assessment (PPA) of the Healy Clean Coal Project (HCCP), selected under Round III of the CCT Program, and described in a Report to Congress (U.S. Department of Energy, 1991). The desire to demonstrate an innovative power plant that integrates an advanced slagging combustor, a heat recovery system, and both high- and low-temperature emissions control processes prompted the Alaska Industrial Development and Export Authority (AIDEA) to submit a proposal for this project. In April 1991, AIDEA entered into a cooperative agreement with DOE to conduct this project. Other team members included Golden Valley Electric Association (GVEA), host and operator; Usibelli Coal Mine, Inc., coal supplier; TRW, Inc., Space & Technology Division, combustor technology provider; Stone & Webster Engineering Corp. (S&W), engineer; Babcock & Wilcox Company (which acquired the assets of Joy Environmental Technologies, Inc.), supplier of the spray dryer absorber technology; and Steigers Corporation, provider of environmental and permitting support. Foster Wheeler Energy Corporation supplied the boiler. GVEA provided oversight of the design and provided operators during demonstration testing. The project was sited adjacent to GVEA's Healy Unit No. 1 in Healy, Alaska. The objective of this CCT project was to demonstrate the ability of the TRW Clean Coal Combustion System to operate on a blend of run-of-mine (ROM) coal and waste coal, while meeting strict environmental requirements. DOE provided $117,327,000 of the total project cost of $282,300,000, or 41.6 percent. Construction for the demonstration project was started in May 1995, and completed in November 1997. Operations were initiated in January 1998, and completed in December 1999. The evaluation contained herein is based primarily on information from the AIDEA's Final Report (Alaska Industrial Development and Export Authority, 2001), as well as other references cited.

Co-processing of agriculture and biomass waste with coal  

SciTech Connect (OSTI)

Biomass and bio-processed waste are potential candidates for co-liquefaction with coal. Specific materials used here include sawdust and poultry manure. Liquefaction experiments were run on each of these materials, separately and with coal, using tetralin as solvent at 350{degrees}C and 1000 psi(cold) hydrogen pressure for 1h. Total conversion was monitored, as well as conversion to asphaltenes, oils and gases. All the biomass samples are converted to oils and gases under the reaction conditions. Poultry manure seems to convert coal more completely, and to produce more oils and gases, than conventional liquefaction.

Deep coal resources in the Cherokee Group (middle Pennsylvanian) in eastern Kansas  

SciTech Connect (OSTI)

Evaluation of over 800 gamma-ray/density and gamma-ray/neutron logs run for oil and gas tests in eastern Kansas shows a wide distribution of coal in the Cherokee Group in this area. With nearly 300 million tons (270 million metric tons) of high-volatile bituminous coal produced in southeastern Kansas, this group was important for further evaluation. Studies of the coals in the Cherokee Group too deep to strip mine in the Cherokee basin and the Forest City basin indicate a coal resource of nearly 50 billion tons (45 billion metric tons). This figure represents coal from 27 different coal beds in the three reliability categories of measured, indicated, and inferred. Most of the coal is recognized as thin bedded (< 28 in. or < 70 cm) like most of the coal beds in the outcrop belt in southeastern Kansas. Six coals beds with a total of over 1.4 billion tons (1.3 billion metric tons) of resources are present where coal thicknesses exceed 42 in. (105 cm) in parts of 12 different counties. Resource quantities of the Cherokee Group coal beds were made using Pacer and Garnet software developed for the National Coal Resources Data System (NCRDS) of the US Geological Survey.

Section 5 - Coal  

Science Journals Connector (OSTI)

Coal has the longest history of use among the fossil fuels, with use as a fuel dating to 3000 BC in China and Wales. Marco Polo’s “Description of the World” (1298) comments on many novel customs and practices of China, including the use of “stones that burn like logs” (coal). By the thirteenth century the mining of coal was widespread in England in regions such as Durham, Nottinghamshire, Derbyshire, Staffordshire, and North and South Wales. By the early seventeenth century nearly half of England’s maritime trade consisted of coal exports. Coal was the fuel that launched the Industrial Revolution in Europe and then the United States. By the late 1890s, the U.S. assumed the lead in world coal production. Britain now ranked second, after having been the world leader since the beginnings of the formal industry in the 1500s. Germany was third, an indication of its growing industrial power relative to continental rival France. Coal’s leading role in energy use peaked in the early twentieth century, after which it was supplanted by oil and natural gas. By the late twentieth century China’s rapid economic expansion, surging demand for electricity, and prodigious coal resources combined to propel it to become the world leader in production. Continuous improvements in coal mining technology have produced lower costs, improved safety, and greater labor productivity. John Buddle introduced the first air pump to ventilate coal mines (1803), followed shortly by the miner’s safety lamps that were developed independently by Sir Humphry Davy, William Clanny, and George Stephenson (1813-1816). Coal mining underwent a rapid transition in the 1880s to mechanical coal cutting in mines in the United Kingdom, the United States, and Russia. The St. Joseph Lead Company of Missouri (1900) invented the first underground mine roof bolts that became a key safety feature in underground coal mines. The first commercially successful bucket wheel excavator was used at the Luise Mine in Braunkohlemwerke, Germany (1925), followed by the first successful continuous miners in U.S. underground coal mining (1948). The first mechanized U.S. longwall mining system appeared in 1951, and was followed by the self-advancing hydraulic longwall support system that provided greater support for the roof of the mine. LeTourneau Technologies, Inc. of Texas manufactured the largest rubber tired front-end wheel loader in the world, the L-2350, which would play an important role in loading coal in Wyoming’s large surface mines (2005). Coal mining has always been a very hazardous occupation, and has produced some of history’s worst industrial disasters. The Courrières mine disaster, Europe's worst mining accident, caused the death of 1,099 miners in Northern France (1906). An explosion in a coal mine in Liaoning province in northeastern China killed more than 1,500 Chinese miners (1942), as did other major accidents in Ky?sh?, Japan (1914), Wankie, Rhodesia (1972), Wales (1913), Bihar, India (1965), and West Virginia, U.S. (1907), to name just a few. Legislation such as the Federal Coal Mine Health and Safety Act in the U.S. (1969) improved working conditions in many nations. The Great Smog of London (1952) occurred after an exceptionally cold winter forced homes and factories to burn large quantities of coal. A temperature inversion formed, trapping pollutants above the ground. More than 4,000 people died from respiratory ailments within the following week. The use of coal has been impacted by legislation to control the environmental impacts associated with its mining and combustion. The first known environmental regulation of coal dates to 1306 when King Edward II of England prohibited burning sea coal while Parliament was in session because of its offensive smoke. Sulfur dioxide from coal combustion was tied to acid rain in the 1960s, and carbon dioxide emissions became a concern beginning in the 1980s when climate change emerged as a critical environmental issue.

Coal science for the clean use of coal  

SciTech Connect (OSTI)

Coal will need to be retained as a major source of energy in the next century. It will need to be used more effectively and more cleanly. In order to achieve this, it is necessary to introduce new technology supported by a local community of science and technology. Only in this way can the full benefits of international advances in coal utilization be fully achieved. It is important that full advantage be taken of the advances that have been achieved in laboratory techniques and in the better understanding of fundamental coal science. This paper reviews available technologies in power generation, industrial process heat, coal combustion, coal gasification, and coal analytical procedures.

Coal-fueled diesel technology development: Nozzle development for coal-fueled diesel engines  

SciTech Connect (OSTI)

Direct injection of a micronized coal water mixture fuel into the combustion chambers of a diesel engine requires atomizing an abrasive slurry fuel with accurately sized orifices. Five injector orifice materials were evaluated: diamond compacts, chemical vapor deposited diamond tubes, thermally stabilized diamond, tungsten carbide with cobalt binder, and tungsten carbide with nickel binder with brazed and mechanically mounted orifice inserts. Nozzle bodies were fabricated of Armco 17-4 precipitation hardening stainless steel and Stellite 6B in order to withstand cyclic injection pressures and elevated temperatures. Based on a total of approximately 200 cylinder hours of engine operation with coal water mixture fuel diamond compacts were chosen for the orifice material.

COAL LOGISTICS. Tracking U.S. Coal Exports  

SciTech Connect (OSTI)

COAL LOGISTICS has the capability to track coal from a U. S. mine or mining area to a foreign consumer`s receiving dock. The system contains substantial quantities of information about the types of coal available in different U. S. coalfields, present and potential inland transportation routes to tidewater piers, and shipping routes to and port capabilities in Italy, Japan, South Korea, Taiwan, and Thailand. It is designed to facilitate comparisons of coal quality and price at several stages of the export process, including delivered prices at a wide range of destinations. COAL LOGISTICS can be used to examine coal quality within or between any of 18 U. S. coalfields, including three in Alaska, or to compare alternative routes and associated service prices between coal-producing regions and ports-of-exit. It may be used to explore the possibilities of different ship sizes, marine routes, and foreign receiving terminals for coal exports. The system contains three types of information: records of coal quality, domestic coal transportation options, and descriptions of marine shipment routes. COAL LOGISTICS contains over 3100 proximate analyses of U. S. steam coals, usually supplemented by data for ash softening temperature and Hardgrove grindability; over 1100 proximate analyses for coals with metallurgical potential, usually including free swelling index values; 87 domestic coal transportation options: rail, barge, truck, and multi-mode routes that connect 18 coal regions with 15 U. S. ports and two Canadian terminals; and data on 22 Italian receiving ports for thermal and metallurgical coal and 24 coal receiving ports along the Asian Pacific Rim. An auxiliary program, CLINDEX, is included which is used to index the database files.

Study of catalytic effects of mineral matter level on coal reactivity  

SciTech Connect (OSTI)

Coal liquefaction experiments using a 400-lb/day bubble-column reactor tested the catalytic effects of added mineral matter level on coal conversion, desulfurization, and distillate yields in continuous operation under recycle conditions, with specific emphasis on the use of a disposable pyrite catalyst indigenous to the feed coal. Western Kentucky No. 11 run-of-mine (ROM) and washed coals were used as feedstocks to determine the effects of levels of mineral matter, specifically iron compounds. Liquefaction reactivity as characterized by total distillate yield was lower for washed coal, which contained less mineral matter. Liquefaction reactivity was regained when pyrite concentrate was added as a disposable catalyst to the washed coal feed in sufficient quantity to match the feed iron concentration of the run-of-mine coal liquefaction test run.

COFIRING BIOMASS WITH LIGNITE COAL  

SciTech Connect (OSTI)

The University of North Dakota Energy & Environmental Research Center, in support of the U.S. Department of Energy's (DOE) biomass cofiring program, completed a Phase 1 feasibility study investigating aspects of cofiring lignite coal with biomass relative to utility-scale systems, specifically focusing on a small stoker system located at the North Dakota State Penitentiary (NDSP) in Bismarck, North Dakota. A complete biomass resource assessment was completed, the stoker was redesigned to accept biomass, fuel characterization and fireside modeling tests were performed, and an engineering economic analysis was completed. In general, municipal wood residue was found to be the most viable fuel choice, and the modeling showed that fireside problems would be minimal. Experimental ash deposits from firing 50% biomass were found to be weaker and more friable compared to baseline lignite coal. Experimental sulfur and NO{sub x} emissions were reduced by up to 46%. The direct costs savings to NDSP, from cogeneration and fuel saving, results in a 15- to 20-year payback on a $1,680,000 investment, while the total benefits to the greater community would include reduced landfill burden, alleviation of fees for disposal by local businesses, and additional jobs created both for the stoker system as well as from the savings spread throughout the community.

A method of extracting coal from a coal refuse pile comprises soaking the coal refuse pile with an aqueous alkali solution and distributing an oxygen-containing gas throughout the coal refuse pile for a time period sufficient to effect oxidation of coal contained in the coal refuse pile. The method further comprises leaching the coal refuse pile with an aqueous alkali solution to solubilize and extract the oxidized coal as alkali salts of humic acids and collecting the resulting solution containing the alkali salts of humic acids. Calcium hydroxide may be added to the solution of alkali salts of humic acid to form precipitated humates useable as a low-ash, low-sulfur solid fuel.

With the advancement in fine coal cleaning technology, recovery of fine coal (minus 28 mesh) has become an attractive route for the U.S. coal industry. The clean coal recovered using the advanced flotation technology i.e. column flotation, contains on average 20% solids and 80% water, with an average particle size of 35 microns. Fine coal slurry is usually dewatered using a vacuum dewatering technique, providing a material with about 25 to 30 percent moisture. The process developed in this project will improve dewatering of fine (0.6mm) coal slurry to less than 20 percent moisture. Thus, thermal drying of dewatered wet coal will be eliminated. This will provide significant energy savings for the coal industry along with some environmental benefits. A 1% increase in recovery of coal and producing a filter cake material of less than 20 % moisture will amount to energy savings of 1900 trillion Btu/yr/unit. In terms of the amount of coal it will be about 0.8% of the total coal being used in the USA for electric power generation. It is difficult to dewater the fine clean coal slurry to about 20% moisture level using the conventional dewatering techniques. The finer the particle, the larger the surface area and thus, it retains large amounts of moisture on the surface. The coal industry has shown some reluctance in using the advanced coal recovery techniques, because of unavailability of an economical dewatering technique which can provide a product containing less than 20% moisture. The U.S.DOE and Industry has identified the dewatering of coal fines as a high priority problem. The goal of the proposed program is to develop and evaluate a novel two stage dewatering process developed at the University of Kentucky, which involves utilization of two forces, namely, vacuum and pressure for dewatering of fine coal slurries. It has been observed that a fine coal filter cake formed under vacuum has a porous structure with water trapped in the capillaries. When this porous cake is subjected to pressure for a short time, the free water present is released from the filter cake. Laboratory studies have shown that depending on the coal type a filter cake containing about 15% moisture could be obtained using the two-stage filtration technique. It was also noted that applying intermittent breaks in vacuum force during cake formation, which disturbed the cake structure, helped in removing moisture from the filter cakes. In this project a novel approach of cleaning coal using column flotation was also developed. With this approach the feed capacity of the column is increased significantly, and the column was also able to recover coarser size coal which usually gets lost in the process. The outcome of the research benefits the coal industry, utility industry, and indirectly the general public. The benefits can be counted in terms of clean energy, cleaner environment, and lower cost power.

Composition and properties of coals from the Yurty coal occurrence  

SciTech Connect (OSTI)

Coals from the Yurty coal occurrence were studied. It was found that the samples were brown non-coking coals with low sulfur contents (to 1%) and high yields of volatile substances. The high heat value of coals was 20.6-27.7 MJ/kg. The humic acid content varied from 5.45 to 77.62%. The mineral matter mainly consisted of kaolinite, a-quartz, and microcline. The concentration of toxic elements did not reach hazardous values.

Establishment and maintenance of a coal sample bank and data base. Final report, April 8, 1988--September 28, 1993  

SciTech Connect (OSTI)

This DOE contract continued support for the DOE Coal Sample Bank and Data Base at Penn State. At the beginning of the contract, a new type of container was evaluated for long-term storage of coal samples ranging in quantity from a few grams to over 10 kg (22 lbs). Gieseler fluid behavior, oxidation of pyrite to sulfates, loss of heating value, and other properties were monitored over time. Based on preliminary results, these foil and polyethylene laminate bags were believed to be a significant improvement over the drums, buckets and cans previously used. Use of the bags was therefore instituted with DECS-1, the first sample collected under the contract. Twenty-two DECS samples were collected, ranging in rank from lignite to anthracite and representing the five most productive coal provinces of the US. Over 6500 containers of DECS samples were created under the contract and 750 containers of 34 PSOC samples are supported by the contract. Each sample was characterized by proximate and ultimate analysis, petrographic (vitrinite reflectance and maceral) analysis, physical and thermoplastic testing, and inorganic element analysis. The resulting data, and geologic data on each sample, were entered in a data base which can be used to produce a formatted five-page or one-page printout for each sample. An interactively operated data base can be searched, sorted or summarized to produce tables of selected data or to identify samples meeting a requestor`s criteria. During the period covered, 2,313 printouts, and 204 special data reports resulting in distribution of data on 34,086 samples, were provided on request.

Coal combustion system  

DOE Patents [OSTI]

In a coal combustion system suitable for a gas turbine engine, pulverized coal is transported to a rich zone combustor and burned at an equivalence ratio exceeding 1 at a temperature above the slagging temperature of the coal so that combustible hot gas and molten slag issue from the rich zone combustor. A coolant screen of water stretches across a throat of a quench stage and cools the combustible gas and molten slag to below the slagging temperature of the coal so that the slag freezes and shatters into small pellets. The pelletized slag is separated from the combustible gas in a first inertia separator. Residual ash is separated from the combustible gas in a second inertia separator. The combustible gas is mixed with secondary air in a lean zone combustor and burned at an equivalence ratio of less than 1 to produce hot gas motive at temperature above the coal slagging temperature. The motive fluid is cooled in a dilution stage to an acceptable turbine inlet temperature before being transported to the turbine.

Dry cleaning of Turkish coal  

SciTech Connect (OSTI)

This study dealt with the upgrading of two different type of Turkish coal by a dry cleaning method using a modified air table. The industrial size air table used in this study is a device for removing stones from agricultural products. This study investigates the technical and economical feasibility of the dry cleaning method which has never been applied before on coals in Turkey. The application of a dry cleaning method on Turkish coals designated for power generation without generating environmental pollution and ensuring a stable coal quality are the main objectives of this study. The size fractions of 5-8, 3-5, and 1-3 mm of the investigated coals were used in the upgrading experiments. Satisfactory results were achieved with coal from the Soma region, whereas the upgrading results of Hsamlar coal were objectionable for the coarser size fractions. However, acceptable results were obtained for the size fraction 1-3 mm of Hsamlar coal.

Distribution of thermogenic methane in Carboniferous coal seams of the Donets Basin (Ukraine): “Applications to exploitation of methane and forecast of mining hazards”  

Science Journals Connector (OSTI)

The main purpose of this contribution is to estimate methane production and to define its migration paths and storage in the Donets Basin formations for exploitation of methane and forecast of mining hazards. In order to study methane migration and storage, maps of production calculated by 2D modelling, adsorption capacity of methane in coal, and present-day methane contents were constructed for an altitude of ? 300 m (close to 500 m depth) in this basin. The results show that three principal factors influenced the methane migration and accumulation in Donets Basin: 1) faults that acted as migration pathways, 2) a replacement of thermogenic methane by endogenic CO2 in the central and SE parts, and 3) the occurrence of magmatic events in some areas in this basin. Finally, in Donbas, the areas with the highest methane potential and the maximum risk of outburst are not the areas with anthracite that produce the highest volume of methane, but areas with volatile bituminous coals where an impermeable cover preserved the accumulated gas until the Cenozoic and where dextral shear belts facilitated its migration.

Characterization of selected Ohio coals to predict their conversion behavior relative to 104 North American Coals. [Factors correlating with liquefaction behavior  

SciTech Connect (OSTI)

Twenty-six coal samples from Ohio were collected as washed and seam samples, and lithobodies within the seams. Characterization of these samples included determination of % maceral, % anti R/sub max/, LTA, chlorine content and proximate/ultimate and qualitative mineral analyses. These data were compared to data from a similar project by Yarzab, R.F., et al., 1980 completed at Pennsylvania State University using tetralin as the hydrogen donor solvent. The characteristics of these coals were correlated with liquefaction conversion and other data accrued on 104 North American coals by statistical analyses. Utilizing percent carbon, sulfur, volatile matter, reflectance, vitrinite and total reactive macerals, Q-mode cluster analysis demonstrated that Ohio coals are more similar to the coals of the Interior province than to those of the Appalachian province. Linear multiple regression analysis for the 104 North American coals provided a prediction equation for conversion (R = .96). The predicted conversion values for the samples range from 58.8 to 79.6%, with the Lower Kittanning (No. 5) and the Middle Kittanning (No. 6) coal seams showing the highest predicted percent conversion (respectively, 73.4 and 72.2%). The moderately low FSI values for the No. 5 and No. 6 coals (respectively, 2.5 and 3) and their moderately high alkaline earth content (respectively, 0.69 and 0.74%) suggest that these coals possess the best overall properties for conversion. Stepwise regression has indicated that the most important coal characteristics affecting conversion are, in decreasing order of importance: % volatile matter, % vitrinite and % total sulfur. Conversion processes can be expected to produce higher yields with Ohio coals due to the presence of such mineral catalysts as pyrite and kaolinite. It is believed that the presence of these disposable catalysts increases the marketability of Ohio coals.

Toxic Substances from Coal Combustion - Forms of Occurrence Analyses  

SciTech Connect (OSTI)

In a cooperative agreement with DOE (Contract No. DE- AC22- 95101), the USGS has participated with Physical Sciences, Inc. (PSI) in a project entitled "Toxic Substances From Coal Combustion -A Comprehensive Assessment". Samples from the Pittsburgh, Elkhorn/ Hazard, Illinois No. 6, and Wyodak program coals were examined to determine the mode of occurrence of selected trace elements (As, Se, Cr, Hg, and Ni) using selective leaching, scanning electron microscopy, electron microprobe analysis, and X- ray diffraction techniques. Among other findings, our results indicate that the bulk of the arsenic in the Pittsburgh and Illinois No. 6 coals is in pyrite. High percentages (60- 80%) of arsenic were leached by nitric acid, and microprobe data confirm the presence of arsenic in pyrite in each of these coals (concentrations ranging from <0.01 to 0.09 wt.% of the pyrite grains). In the Elkhorn/ Hazard coal, arsenic may have several modes of occurrences. About 30 percent of the arsenic in the Elkhorn/ Hazard coal was leached by hydrochloric acid, possibly indicating the presence of arsenates that were formed by the oxidation of pyrite. About 25 percent of the arsenic in the Elkhorn/ Hazard coal was leached by nitric acid, suggesting an association with pyrite. Only sixty percent of the total arsenic in the Elkhorn/ Hazard coal was leached. The low percentage of leachable arsenic may be accounted for by unleached pyrite grains, which were detected in solid residues from the nitric acid leach. In the Wyodak coal, arsenic probably occurs in iron oxides or carbonates (35 % arsenic leached by HCl) and clays (15% arsenic leached by HF). Arsenic in the Wyodak coal may also have an organic association, as indicated by low totals for leaching (50% unleached arsenic). In the four program coals 20 to 45 percent of the chromium was leached by hydrofluoric acid, suggesting an association with silicates (probably illite). Microprobe analysis of the Pittsburgh, Elkhorn/ Hazard, and Illinois No. 6 coals confirmed the presence of chromium in illite and possibly in other clays, at concentrations that are near the detection limits. Results related to the forms of occurrence of the other trace elements (Se, Hg, and Ni) are varied; further work in Phase II is planned to determine their mode of occurrence.

Process for coal liquefaction employing selective coal feed  

DOE Patents [OSTI]

An improved coal liquefaction process is provided whereby coal conversion is improved and yields of pentane soluble liquefaction products are increased. In this process, selected feed coal is pulverized and slurried with a process derived solvent, passed through a preheater and one or more dissolvers in the presence of hydrogen-rich gases at elevated temperatures and pressures, following which solids, including mineral ash and unconverted coal macerals, are separated from the condensed reactor effluent. The selected feed coals comprise washed coals having a substantial amount of mineral matter, preferably from about 25-75%, by weight, based upon run-of-mine coal, removed with at least 1.0% by weight of pyritic sulfur remaining and exhibiting vitrinite reflectance of less than about 0.70%.

Chapter 8 - Coal Seam Degasification  

Science Journals Connector (OSTI)

Abstract The chapter discusses various techniques for coal seam degasification. All coal seams are gassy but they differ in their degree of gassiness. Pre-mining and post-mining techniques for underground coal mines are discussed. With good planning, 50–80% of in-situ gas in coal can be removed before mining improving both safety and productivity. Similarly, 50–80% of gas from mined-out areas (gobs) can be removed to minimize ventilation air requirements. Gas transport in underground mines and economics of coal seam degasification are also discussed.

4 - Coal resources and reserves  

Science Journals Connector (OSTI)

Abstract: Coal resources still make up a significant proportion of the world’s energy supplies. Coal resources are estimated to be 860 billion tonnes. These resources are geographically well distributed and current production provides fuel for 29% of the world’s primary energy consumption. The classification of coal resources and reserves has been redefined in recent years, with the standards and codes of practice adopted by the principal coal-producing countries being equated on a global basis. Details of the principal classifications are given, together with their international equivalents. Reporting of resources and reserves plus methods of calculation are also given, together with recent assessments of global coal reserves.

Fort Union coals of the northern Rockies and Great Plains: A linchpin toward a new approach to national coal resource assessment  

SciTech Connect (OSTI)

The U.S. Geological Survey recently initiated a 5-year program to assess the Nation`s coal resources, which emphasizes a new approach relating coal quantity and quality. One assessment region includes the northern Rocky Mountains and Great Plains of Wyoming, Montana, and North Dakota, which contains a vast expanse of Paleocene Fort Union coal-bearing rocks that yielded about 30% (>299 million short tons) of the total coal produced (1.03 billion short tons) in the U.S. for 1994. Production is from 14 coal beds/zones (Wyodak-Anderson, Anderson-Dietz, Rosebud, Beulah-Zap, Hagel, Harmon, Ferris Nos. 23, 24, 25, 31, 38, 39, Hanna No. 80, and Deadman seams) mined in the Hanna, Green River, Powder River, and Williston Basins. About 254 million short tons produced from 25 mines are from the Wyodak-Anderson, Anderson-Dietz, and Rosebud coal beds/zones in the Powder River Basin (PRB). These coals are considered as clean and low contaminant compliance coals containing less sulfur and ash (arithmetic mean for sulfur is 0.58% and ash is 7%, as-received basis) than coals produced from other regions in the conterminous U.S. Preliminary elemental analysis of coal samples from the PRB for those hazardous air pollutants (HAPs) named in the Amendments to the 1990 Clean Air Act (including Sb, As, Be, Cd, Cr, Co, Pb, Mn, Hg, Ni, Se, and U), indicates that PRB coals are lower in HAPs contents than other coals from within the region and also other regions in the U.S. Arithmetic means of HAPs contents of these coals are: Sb=0.35, As=3.4, Be=0.6, Cd=0.08, Cr=6.1, Co=1.6, Pb=3.6, Mn=23.5, Hg=0.09, Ni=4.6, Se=0.9, and U=1.1 (in ppm, as-received, and on a whole-coal basis). These coal-quality parameters will be used to delineate coal quantity of the 14 Fort Union coal beds/zones defined in the resource assessment for expanded utilization of coals into the next several decades as controlled by present and future environmental constraints.

Coal-oil slurry preparation  

DOE Patents [OSTI]

A pumpable slurry of pulverized coal in a coal-derived hydrocarbon oil carrier which slurry is useful as a low-ash, low-sulfur clean fuel, is produced from a high sulfur-containing coal. The initial pulverized coal is separated by gravity differentiation into (1) a high density refuse fraction containing the major portion of non-coal mineral products and sulfur, (2) a lowest density fraction of low sulfur content and (3) a middlings fraction of intermediate sulfur and ash content. The refuse fraction (1) is gasified by partial combustion producing a crude gas product from which a hydrogen stream is separated for use in hydrogenative liquefaction of the middlings fraction (3). The lowest density fraction (2) is mixed with the liquefied coal product to provide the desired fuel slurry. Preferably there is also separately recovered from the coal liquefaction LPG and pipeline gas.

Characteristics of coking coal burnout  

SciTech Connect (OSTI)

An attempt was made to clarify the characteristics of coking coal burnout by the morphological analysis of char and fly ash samples. Laboratory-scale combustion testing, simulating an ignition process, was carried out for three kinds of coal (two coking coals and one non-coking coal for reference), and sampled chars were analyzed for size, shape and type by image analysis. The full combustion process was examined in industrial-scale combustion testing for the same kinds of coal. Char sampled at the burner outlet and fly ash at the furnace exit were also analyzed. The difference between the char type, swelling properties, agglomeration, anisotropy and carbon burnout were compared at laboratory scale and at industrial scale. As a result, it was found that coking coals produced chars with relatively thicker walls, which mainly impeded char burnout, especially for low volatile coals.

Coal Cleaning Using Resonance Disintegration for Mercury and Sulfur Reduction Prior to Combustion  

SciTech Connect (OSTI)

Coal-cleaning processes have been utilized to increase the heating value of coal by extracting ash-forming minerals in the coal. These processes involve the crushing or grinding of raw coal followed by physical separation processes, taking advantage of the density difference between carbonaceous particles and mineral particles. In addition to the desired increase in the heating value of coal, a significant reduction of the sulfur content of the coal fed to a combustion unit is effected by the removal of pyrite and other sulfides found in the mineral matter. WRI is assisting PulseWave to develop an alternate, more efficient method of liberating and separating the undesirable mineral matter from the carbonaceous matter in coal. The approach is based on PulseWave's patented resonance disintegration technology that reduces that particle size of materials by application of destructive resonance, shock waves, and vortex generating forces. Illinois No.5 coal, a Wyodak coal, and a Pittsburgh No.8 coal were processed using the resonance disintegration apparatus then subjected to conventional density separations. Initial microscopic results indicate that up to 90% of the pyrite could be liberated from the coal in the machine, but limitations in the density separations reduced overall effectiveness of contaminant removal. Approximately 30-80% of the pyritic sulfur and 30-50% of the mercury was removed from the coal. The three coals (both with and without the pyritic phase separated out) were tested in WRI's 250,000 Btu/hr Combustion Test Facility, designed to replicate a coal-fired utility boiler. The flue gases were characterized for elemental, particle bound, and total mercury in addition to sulfur. The results indicated that pre-combustion cleaning could reduce a large fraction of the mercury emissions.

Underground Coal Thermal Treatment  

SciTech Connect (OSTI)

The long-term objective of this work is to develop a transformational energy production technology by insitu thermal treatment of a coal seam for the production of substitute natural gas (SNG) while leaving much of the coalâ??s carbon in the ground. This process converts coal to a high-efficiency, low-GHG emitting gas fuel. It holds the potential of providing environmentally acceptable access to previously unusable coal resources. This topical report discusses the development of experimental capabilities, the collection of available data, and the development of simulation tools to obtain process thermo-chemical and geo-thermal parameters in preparation for the eventual demonstration in a coal seam. It also includes experimental and modeling studies of CO{sub 2} sequestration. Efforts focused on: â?¢ Constructing a suite of three different coal pyrolysis reactors. These reactors offer the ability to gather heat transfer, mass transfer and kinetic data during coal pyrolysis under conditions that mimic in situ conditions (Subtask 6.1). â?¢ Studying the operational parameters for various underground thermal treatment processes for oil shale and coal and completing a design matrix analysis for the underground coal thermal treatment (UCTT). This analysis yielded recommendations for terms of targeted coal rank, well orientation, rubblization, presence of oxygen, temperature, pressure, and heating sources (Subtask 6.2). â?¢ Developing capabilities for simulating UCTT, including modifying the geometry as well as the solution algorithm to achieve long simulation times in a rubblized coal bed by resolving the convective channels occurring in the representative domain (Subtask 6.3). â?¢ Studying the reactive behavior of carbon dioxide (CO{sub 2}) with limestone, sandstone, arkose (a more complex sandstone) and peridotite, including mineralogical changes and brine chemistry for the different initial rock compositions (Subtask 6.4). Arkose exhibited the highest tendency of participating in mineral reactions, which can be attributed to the geochemical complexity of its initial mineral assemblage. In experiments with limestone, continuous dissolution was observed with the release of CO{sub 2} gas, indicated by the increasing pressure in the reactor (formation of a gas chamber). This occurred due to the lack of any source of alkali to buffer the solution. Arkose has the geochemical complexity for permanent sequestration of CO{sub 2} as carbonates and is also relatively abundant. The effect of including NH{sub 3} in the injected gas stream was also investigated in this study. Precipitation of calcite and trace amounts of ammonium zeolites was observed. A batch geochemical model was developed using Geochemists Workbench (GWB). Degassing effect in the experiments was corrected using the sliding fugacity model in GWB. Experimental and simulation results were compared and a reasonable agreement between the two was observed.

Comparative results of the combustion of lignin briquettes and black coal  

SciTech Connect (OSTI)

A new type of biofuel - hydrolytic lignin briquettes - was tested as compared with ordinary SS coal from the Kuznetsk Basin in fuel-bed firing in a Universal-6 boiler. It was found that the (total) efficiency of the boiler with the firing of lignin briquettes was 38% higher than that with the use of black coal. Carbon loss in the combustion of briquettes was 1%, whereas it was 48.2% in the combustion of black coal. The emission of harmful gas pollutants into the environment in the combustion of briquettes was lower than that in the combustion of coal by a factor of 4.5.

Moist caustic leaching of coal  

DOE Patents [OSTI]

A process for reducing the sulfur and ash content of coal. Particulate coal is introduced into a closed heated reaction chamber having an inert atmosphere to which is added 50 mole percent NaOH and 50 mole percent KOH moist caustic having a water content in the range of from about 15% by weight to about 35% by weight and in a caustic to coal weight ratio of about 5 to 1. The coal and moist caustic are kept at a temperature of about 300.degree. C. Then, water is added to the coal and caustic mixture to form an aqueous slurry, which is washed with water to remove caustic from the coal and to produce an aqueous caustic solution. Water is evaporated from the aqueous caustic solution until the water is in the range of from about 15% by weight to about 35% by weight and is reintroduced to the closed reaction chamber. Sufficient acid is added to the washed coal slurry to neutralize any remaining caustic present on the coal, which is thereafter dried to produce desulfurized coal having not less than about 90% by weight of the sulfur present in the coal feed removed and having an ash content of less than about 2% by weight.

Coal cleaning program for Kazakstan  

SciTech Connect (OSTI)

In 1992 the United States Agency for International Development (USAID) started sponsoring general projects in the Energy and Environmental Sector to improve health and well-being, to improve the efficiency of the existing fuel and energy base, and to assist in the establishment of a strong private sector. Coal Cleaning Program, covered in this report, is one of the recently completed projects by Burns and Roe, which is a prime USAID contractor in the field of energy and environment for the NIS. The basis for coal cleaning program is that large coal resources exist in northeast Kazakstan and coal represents the major fuel for heat and electricity generation at present and in the foreseeable future. The coal mined at Karaganda and Ekibastuz, the two main coal mining areas of Kazakstan, currently contains up to 55% ash, whereas most boilers in Kazakstan are designed to fire a coal with an ash content no greater than 36%. The objective of the task was to determine optimum, state-of-the-art coal cleaning and mining processes which are applicable to coals in Kazakstan considering ultimate coal quality of 36% ash, environmental quality, safety and favorable economics.

The Wyodak-Anderson coal assessment, Powder River Basin, Wyoming and Montana -- An ArcView project  

SciTech Connect (OSTI)

In 1997, more than 305 million short tons of clean and compliant coal were produced from the Wyodak-Anderson and associated coal beds and zones of the Paleocene Fort Union Formation in the Powder River Basin, Wyoming and Montana. To date, all coal produced from the Wyodak-Anderson, which averages 0.47 percent sulfur and 6.44 percent ash, has met regulatory compliance standards. Twenty-eight percent of the total US coal production in 1997 was from the Wyodak-Anderson coal. Based on the current consumption rates and forecast by the Energy Information Administration (1996), the Wyodak-Anderson coal is projected to produce 413 million short tons by the year 2016. In addition, this coal deposit as well as other Fort Union coals have recently been targeted for exploration and development of methane gas. New US Geological Survey (USGS) digital products could provide valuable assistance in future mining and gas development in the Powder River Basin. An interactive format, with querying tools, using ArcView software will display the digital products of the resource assessment of Wyodak-Anderson coal, a part of the USGS National Coal Resource Assessment of the Powder River Basin. This ArcView project includes coverages of the data point distribution; land use; surface and subsurface ownerships; coal geology, stratigraphy, quality and geochemistry; and preliminary coal resource calculations. These coverages are displayed as map views, cross sections, tables, and charts.

Process for changing caking coals to noncaking coals  

DOE Patents [OSTI]

Caking coals are treated in a slurry including alkaline earth metal hydroxides at moderate pressures and temperatures in air to form noncaking carbonaceous material. Hydroxides such as calcium hydroxide, magnesium hydroxide or barium hydroxide are contemplated for slurrying with the coal to interact with the agglomerating constituents. The slurry is subsequently dewatered and dried in air at atmospheric pressure to produce a nonagglomerating carbonaceous material that can be conveniently handled in various coal conversion and combustion processes.

Central Appalachia: Production potential of low-sulfur coal  

SciTech Connect (OSTI)

The vast preponderance of eastern US low sulfur and 1.2-lbs SO{sub 2}/MMBtu compliance coal comes from a relatively small area composed of 14 counties located in eastern Kentucky, southern West Virginia and western Virginia. These 14 counties accounted for 68% of all Central Appalachian coal production in 1989 as well as 85% of all compliance coal shipped to electric utilities from this region. A property-by-property analysis of total production potential in 10 of the 14 counties (Floyd, Knott, Letcher, Harlan, Martin and Pike in Kentucky and Boone, Kanawha, Logan and Mingo in West Virginia) resulted in the following estimates of active and yet to be developed properties: (1) total salable reserves for all sulfur levels were 5.9 billion tons and (2) 1.2-lbs. SO{sub 2}/MMBtu compliance'' reserves totaled 2.38 billion tons. This potential supply of compliance coal is adequate to meet the expanded utility demand expected under acid rain for the next 20 years. Beyond 2010, compliance supplies will begin to reach depletion levels in some areas of the study region. A review of the cost structure for all active mines was used to categorize the cost structure for developing potential supplies. FOB cash costs for all active mines in the ten counties ranged from $15 per ton to $35 per ton and the median mine cost was about $22 per ton. A total of 47 companies with the ability to produce and ship coal from owned or leased reserves are active in the ten-county region. Identified development and expansion projects controlled by active companies are capable of expanding the region's current production level by over 30 million tons per year over the next twenty years. Beyond this period the issue of reserve depletion for coal of all sulfur levels in the ten county region will become a pressing issue. 11 figs., 12 tabs.

Coal Bed Methane Primer  

SciTech Connect (OSTI)

During the second half of the 1990's Coal Bed Methane (CBM) production increased dramatically nationwide to represent a significant new source of income and natural gas for many independent and established producers. Matching these soaring production rates during this period was a heightened public awareness of environmental concerns. These concerns left unexplained and under-addressed have created a significant growth in public involvement generating literally thousands of unfocused project comments for various regional NEPA efforts resulting in the delayed development of public and fee lands. The accelerating interest in CBM development coupled to the growth in public involvement has prompted the conceptualization of this project for the development of a CBM Primer. The Primer is designed to serve as a summary document, which introduces and encapsulates information pertinent to the development of Coal Bed Methane (CBM), including focused discussions of coal deposits, methane as a natural formed gas, split mineral estates, development techniques, operational issues, producing methods, applicable regulatory frameworks, land and resource management, mitigation measures, preparation of project plans, data availability, Indian Trust issues and relevant environmental technologies. An important aspect of gaining access to federal, state, tribal, or fee lands involves education of a broad array of stakeholders, including land and mineral owners, regulators, conservationists, tribal governments, special interest groups, and numerous others that could be impacted by the development of coal bed methane. Perhaps the most crucial aspect of successfully developing CBM resources is stakeholder education. Currently, an inconsistent picture of CBM exists. There is a significant lack of understanding on the parts of nearly all stakeholders, including industry, government, special interest groups, and land owners. It is envisioned the Primer would being used by a variety of stakeholders to present a consistent and complete synopsis of the key issues involved with CBM. In light of the numerous CBM NEPA documents under development this Primer could be used to support various public scoping meetings and required public hearings throughout the Western States in the coming years.

Zero emission coal  

SciTech Connect (OSTI)

We discuss a novel, emission-free process for producing hydrogen or electricity from coal. Even though we focus on coal, the basic design is compatible with any carbonaceous fuel. The process uses cyclical carbonation of calcium oxide to promote the production of hydrogen from carbon and water. The carbonation of the calcium oxide removes carbon dioxide from the reaction products and provides the additional energy necessary to complete hydrogen production without additional combustion of carbon. The calcination of the resulting calcium carbonate is accomplished using the high temperature waste heat from solid oxide fuel cells (SOFC), which generate electricity from hydrogen fuel. Converting waste heat back to useful chemical energy allows the process to achieve very high conversion efficiency from fuel energy to electrical energy. As the process is essentially closed-loop, the process is able to achieve zero emissions if the concentrated exhaust stream of CO{sub 2} is sequestered. Carbon dioxide disposal is accomplished by the production of magnesium carbonate from ultramafic rock. The end products of the sequestration process are stable naturally occurring minerals. Sufficient rich ultramafic deposits exist to easily handle all the world's coal.

Advanced coal-fueled gas turbine systems. Final report  

SciTech Connect (OSTI)

The configuration of the subscale combustor has evolved during the six years of this program from a system using only an impact separator to remove particulates to a system which also included a slagging cyclone separator before the lean-quench combustor. The system also now includes active slag tapping after the impact separator rather than a bucket to collect the slag. The subscale 12 MM Btu/hr (higher heating value, HHV) slagging combustor has demonstrated excellent coal-fired operation at 6 atm. The combustor has fired both coal-water mixtures (CWM) and pulverized coal (PC). Three Wyoming subbituminous coals and two bituminous coals have been successfully fired in the TVC. As a result of this active testing, the following conclusions may be drawn: (1) it was possible to achieve the full design thermal capacity of 12 MM Btu/hr with the subscale slagging combustor, while burning 100% pulverized coal and operating at the design pressure of 6 atm; (2) because of the separate-chamber, rich-lean design of the subscale slagging combustor, NO{sub x} emissions that easily meet the New Source Performance Standards (NSPS) limits were achieved; (3) carbon burnout efficiency was in excess of 99% when 100% coal-fired; (4) ninety percent of the ash can be separated as slag in the impact separator, and a total 98 to 99% removed with the addition of the slagging cyclone separator; (5) Objectives for third-stage exit temperature (1850{degrees}F), and exit temperature pattern factor (14%) were readily achieved; (6) overall pressure loss is currently an acceptable 5 to 6% without cyclone separator and 7 to 9% with the cyclone; and (7) feeding pulverized coal or sorbent into the combustor against 6 atm pressure is achievable.

Appalachia: the land of coal  

SciTech Connect (OSTI)

The Appalachian region of the United States is an area known worldwide for its long history as a source of coal. If any area of the Unted States is to gain from the projected growth of the coal industry, both domestic and international, it would surely be the coal mining areas of this region, including its biggest coal producing states - Pennsylvania, West Virginia, Kentucky and Ohio. An important facet of the region's coal industry is not only the presence of the giant coal companies but also the small, independent operator. These men are owner-operators and every dollar spent for their operations must bring a return. There is no room for error. WORLD COAL editors have recently traveled to areas in Appalachia and visited mines that are run by these independent operators. One such area was Harlan County, Kentucky. Virtually all mining done in Harlan is underground. Shaft mines are uncommon; most operations have access to exposed seams in the hillsides. Most of the small operations in this region use room and pillar mining and productivity is quite good. It is imperative that the transportation infrastructure be improved so that the expected increased movement of coal out of the region be handled efficiently. Potential domestic consumers of coal from Appalachia are numerous. New England, New York, the mid-Atlantic states, and the South are all looking to this nearby region to help reduce their dependence on oil. Other countries also are looking to the area.
