Description
Summary:The objective of this project is to evaluate and demonstrate a cost effective emission control technology for acid rain precursors, oxides of nitrogen (NO[sub x]) and sulfur (SO[sub x]) on two coal fired utility boilers in Illinois. The units selected are representative of pre-NSPS design practices: tangential and cyclone fired. Work on a third unit, wall fired, has been stopped because of funding limitations. The specific objectives are to demonstrate reductions of 60 percent in NO[sub x] and 50 percent in SO[sub x] emissions, by a combination of two developed technologies, gas reburning (GR) and sorbent injection (SI). With GR, about 80--85 percent of the coal fuel is fired in the primary combustion zone. The balance of the fuel is added downstream as natural gas to create a slightly fuel rich environment in which NO[sub x] is converted to N[sub 2]. The combustion process is completed by overfire air addition. So[sub x] emissions are reduced by injecting dry sorbents (usually calcium based) into the upper furnace. The sorbents trap SO[sub x] as solid sulfates that are collected in the particulate control device. This project is conducted in three phases at each site: (1) Design and Permitting; (2) Construction and Startup; and, (3) Operation, Data Collection, Reporting and Disposition. Technology transfer to industry is accomplished through the formation of an industry panel.
