Enhancing the use of coals by gas reburning-sorbent injection

Technical Report · Fri Jan 25 04:00:00 EST 1991

OSTI ID:5790898

This Clean Coal Technology project will demonstrate a combination of two developed technologies to reduce both NO{sub x}, and SO{sub x} emissions: gas reburning and calcium based dry sorbent injection. The demonstration will be conducted on two pre-NSPS utility boilers representative of the US boilers which contribute significantly to the inventory of acid rain precursor emissions: tangentially and cyclone fired units. Work beyond design and permitting on a third unit, a wall fired boiler, is on hold'' at present because of unavailability of funding. At the inception of the project, Host Site Agreements were signed by EER and three utility companies in the State of Illinois: Site A, Illinois Power Company (Hennepin Unit 1, 71 MW (net) tangentially fired boiler in Hennepin); Site B, Central Illinois Light Company (Edwards Unit 1, 117 MW (net) front wall fired boiler Bartonville); and Site C, City Water Light and Power (Lakeside Unit 7, 33 MW (net) cyclone fired boiler in Springfield). In accordance with the cooperative agreement, EER has prepared an Environmental Monitoring Plan to verify that no adverse environmental impacts would be associated with the project, to determine if projected emission control levels are being met, and to maintain a data base for future development of GR-SI technology. This report provides a description of the monitoring which has been conducted during the previous quarter at the host sites. A discussion of the monitoring results is presented and any proposed changes in the original monitoring plan based on available information is discussed. 5 tabs.
