Abstract

The report gives results of the operation of a 13.8-kW Limestone Injection Multistage Burner (LIMB) furnace. Furnace characterization, general sorbent survey, and calcium silicate test results are also given. Several candidate sorbent materials for the full-scale LIMB demonstration at Edgewater Station (Ohio) were evaluated. SO2 capture was measured while firing Pittsburgh No. 8 coal (2.6% sulfur) and natural gas spiked with SO2. Sorbent was injected at 1210 C. With a furnace quench rate of 260 C/s, the average residence time at reaction temperatures was 1.3 s. At Ca/S molar ratios of 2, Vicron 45-3 limestone reduced SO2 emissions 38% from baseline levels. Increased SO2 capture rates of 60-69% were measured for various calcitic atmospheric hydrates. Dolomitic sorbents were able to achieve captures of 73-75% and showed no significant difference between atmospheric and pressure hydrates. With the addition of sodium bicarbonate at molar Ca/Na = 15, captures of 83 and 88% were possible for the calcitic and dolomitic hydrates, respectively. Sodium bicarbonate was evaluated as a fuel additive as well as a sorbent additive.

LIMB Demonstration Project Extension and Coolside Demonstration. [Final report]

Technical Report Goots, T; DePero, M; Nolan, P

This report presents results from the limestone Injection Multistage Burner (LIMB) Demonstration Project Extension. LIMB is a furnace sorbent injection technology designed for the reduction of sulfur dioxide (SO{sub 2}) and nitrogen oxides (NO{sub x}) emissions from coal-fired utility boilers. The testing was conducted on the 105 Mwe, coal-fired, Unit 4 boiler at Ohio Edison`s Edgewater Station in Lorain, Ohio. In addition to the LIMB Extension activities, the overall project included demonstration of the Coolside process for S0{sub 2} removal for which a separate report has been issued.

Demonstration of sorbent-injection technology on a wall-fired utility boiler (Edgewater LIMB demonstration). Final report, Sep 84-Jun 89

Technical Report Nolan, P; Becker, T; Rodemeyer, P; ...

The report gives results of the full-scale demonstration of Limestone Injection Multistage Burner (LIMB) technology on the coal-fired, 105 MW, Unit 4 boiler at Ohio Edison's Edgewater Station. Developed as a technology aimed at moderate levels of sulfur dioxide (SO2) and nitrogen oxides (NOx) emissions control for relatively low-cost retrofit applications on older plants, LIMB operation at a calcium to sulfur (Ca/S) molar ratio of 2.0 is shown to be capable of achieving about 55 to 72% SO2 removal. Sorbents tested included a commercial calcitic hydrated lime, both with and without a small amount of calcium lignosulfonate, a material addedmore »« less

Control of SOx emissions by in-furnace sorbent injection: carbonates vs hydrates

Technical Report Newton, G; Harrison, D; Silcox, G; ...

The paper provides high-temperature isothermal data on SO/sub 2/ capture by calcium-based sorbents, obtained in a dispersed-phase reactor for limestones, dolomites, hydrated calcitic limes, and hydrated dolomitic limes as a function of Ca/S molar ratio, temperature, and SO/sub 2/ partial pressure. The experimental results indicate that SO/sub 2/ capture is approximately linearly dependent on Ca/S molar ratio and relatively insensitive to SO/sub 2/ partial pressure above 2000 ppm. SO/sub 2/ capture is a strong function of general sorbent class; dolomitic sorbents are better than calcitic materials on an equivalent calcium basis, and hydrated materials are more reactive than carbonates.

Results from LIMB extension testing at the Ohio Edison Edgewater Station

Conference Goots, T; DePero, M; Purdon, T; ...

The primary purpose of the DOE extension testing, which began in April 1990, was to demonstrate the generic applicability of Limestone Injection Multistage Burner (LIMB) technology. The program sought to characterize the SO{sub 2} emissions that result when various calcium-based sorbents are injected into the furnace, while burning coals with a range of sulfur content from 1.6 to 3.8 percent. The four sorbents used included calcitic limestone, dolomitic hydrated lime, calcitic hydrated lime, and calcitic hydrated lime with a small amount of added calcium lignosulfonate. The initial EPA program focused on tests with the calcitic hydrated lime while burning amore »« less
