Characterization of Oxy-combustion Impacts in

2019-11-19 · 4) Assessment of oxy-combustion impacts in two full-scale coal-fired utility boiler retrofits based on computational fluid dynamics (CFD) modeling of air-fired and oxygen-fired operation. This research determined that it is technically feasible to retrofit the combustion system in an air-fired boiler for oxy-fired operation.

2006-2-9 · The subbituminous coal fired boilers in the state (including those that burn primarily subbituminous coal and a small amount of bituminous coal) generally have cold-side ESP's, with a small number of units equipped with hot-side ESPs. The units with cold-side ESP's can be effectively controlled with halogenated sorbent.

Control of Mercury Emissions from Coal-fired Electri

2016-7-28 · average capture of Hg in plants equipped with a CS-ESP is 36 percent for bituminous coal, 3 percent for subbituminous coal, and 0 percent for lignite. Based on ICR data, it is estimated that existing controls remove about 36% of the 75 tons of mercury input with coal in U.S. coal-fired boilers. This results in current emissions of 48 tons of

2015-3-9 · A sorbent is used to capture toxic pollutants in the flue gas produced by the coal-fired boiler of a power plant. (EPA) and the U.S. Congress are currently considering the degree to which mercury emissions from coal-fired power plants in the United States It is

Experimental characterization of an industrial

2019-11-15 · Measurements have been performed in a 300 MWe, front-wall-fired, pulverized-coal, utility boiler. This boiler was retrofitted with boosted over fire air injectors that allowed the operation of the furnace under deeper staging conditions. New data are reported for local mean gas species concentration
