Title: A demonstration test and evaluation of the Cannon Low-NO{sub x} Digester System. Final report

Abstract

Since 1985, Cannon Boiler Works, Inc. has been carrying out research and development efforts to perfect a system for removing nitrogen oxides, NO{sub x}, from the exhaust gases of furnaces, gas turbines, chemical reactors, incinerators and boilers.Computer simulations, bench-scale tests and pilot plant testing have proved that the system is capable of removing substantially all of the NO{sub x} from natural gas-fired equipment exhaust streams. Furthermore when retrofit to industrial boilers, both capital costs and operating costs are lower than for competing processes, while performance is much better. The Cannon system for removing NO{sub x}, originally designated as the Cannon NO{sub x} Digester, has recently been renamed the Low Temperature Oxidation (LTO) System for NO{sub x} and SO{sub x} Reduction. It will be engineered and marketed by Cannon Technology, Inc, a wholly owned subsidiary of Cannon Boiler Works, Inc. Cannon has US patents for the process and for the associated equipment and has patent applications pending in Europe. Cannon`s Low Temperature Oxidation, LTO, process has proved effective for reducing the levels of NO{sub x}, CO, CO{sub 2}, SO{sub 2} and particulates from boiler flue gases.

  • Cannon Boiler Works Inc. has been investigating a system for removing NOx from the exhaust gases of furnaces, gas turbines, chemical reactors, incinerators, and boilers. Computer simulations, bench-scale and pilot plant tests have proved that the system is capable of removing substantially all of the NOx from natural gas fired equipment exhaust streams. Originally designated as the Cannon NOx Digester, it has recently been renamed the Low Temperature Oxidation (LTO) System for NOx and SOx Reduction. The principal elements in the system are a fan, heat exchanger, oxidation chamber, spray chamber acting as a gas/liquid absorber, demister, an ozone generator,more » liquid oxygen storage or dry air supply system for the ozonator, chemical storage and metering system for the caustic neutralizer, and a data acquisition and control system. Most of the ozone is consumed in converting NOx to N{sub 2}O{sub 5} which hydrates to nitric acid which is then scrubbed out of the gas as it passes through the absorber. CO also reacts with ozone to form CO{sub 2} which is subsequently scrubbed out with NaOH. A demonstration, planned for the Alta Dena Dairy located near Los Angeles and in violation of California`s air quality regulations for natural gas fired boilers, was started, delayed due to boiler modifications, and will be continued shortly with new funding. This paper describes the LTO process and presents results from the initial demonstration.« less

  • As a deliverable of the project, ABB Environmental Systems has written this subsystem test plan to outline and detail activities to be undertaken in Tasks 10 and 11 of the Low Emissions Boiler System project. This subsystem test plan includes the budget and schedule for the construction, modification and operation of the subsystem test unit. This subsystem test plan also discusses securing of all applicable construction and operating permits, completing all necessary agreements with any host facilities, management procedures for monitoring and controlling all procurement and construction activities, implementation of Quality Assurance/Quality Control (QA/QC) measures, data acquisition during operations, datamore » analysis, and the startup and shutdown procedures of the test unit. The subsystem test plan is part of the updated Phase II RD&T Plan.« less

    The report discusses Phase I (a conceptual design, preliminary cost, and evaluation study) of a program to demonstrate the recovery of energy from waste methane produced by anaerobic digestion of waste water treatment sludge. The fuel cell is being used for this application because it is potentially one of the cleanest energy technologies available. The program is focused on utilizing a commercial Phosphoric Acid Fuel Cell (PAFC) power plant because of its inherently high fuel efficiency, low emissions characteristics, and high state of development. The environmental impact of widespread use of this concept would be a significant reduction in globalmore » warming and acid rain air emissions.« less

    A new low-NO/sub x/ firing system for tangentially-fired boilers, called the Pollution Minimum or PM firing system, was recently developed by Mitsubishi Heavy Industries (MHI) of Japan in response to that country's stringent NO/sub x/ emission regulations. The Electric Power Research Institute contracted with MHI and Combustion Engineering, Inc. to evaluate this technology for US coal-fired utility boiler applications. The evaluation consisted of (1) pilot-scale combustion tests with an 80 MBtu/h prototype PM firing system, and (2) an engineering and economic feasibility study of applying the PM system at new and retrofit US utility applications. The combustion test used fourmore » US coals representing a wide range of US coal properties and utility usage: (1) low-sulfur eastern bituminous; (2) high-sulfur midwestern bituminous; (3) high-nitrogen, low-sulfur western sub-bituminous; and (4) Texas lignite. The tests verified that NO/sub x/ emission levels in the 150 ppM range (corrected to 3% O/sub 2/) are achievable with all four coals using the PM firing system. These low NO/sub x/ emissions were achieved without adverse effects on carbon conversion, ignition stability, and overall combustion performance. The applicability of the PM firing system in tangentially-fired steam generators was examined for retrofit and new units through case studies based on actual designs for US steam generators. This examination revealed that the desired level of NO/sub x/ emissions will affect the complexity of the firing system modifications, especially for retrofit cases. For retrofit installations, this complexity was influenced by site-specific factors peculiar to each boiler. Guarantees of lower NO/sub x/ emissions near 150 ppM (0.2 lb/10/sup 6/ Btu) result in more elaborate systems and higher costs. 9 refs., 66 figs., 22 tabs.« less

  • A Superfund Innovative Technology Evaluation (SITE) Program demonstrated the Shirco Infrared System (pilot plant) for thermally processing PCB waste at Rose Township, Michigan. The process was evaluated by the U.S. EPA and is reported in Volume I of the report. Results reported in Volume I indicated that PCB was removed from the feed material with a DRE greater than 99.99%. The destructive ratio (percent of PCB in the ash compared to feed) was greater than 83% resulting in a less than 1 ppm concentration in the ash. Particulate emissions, products of incomplete combustion (PICs) and acid-gas emissions were below anymore » standards. Metals in the ash leached by the TCLP and EP Tox. were below suggested standards.« less
