Coal reburning for cyclone boiler NO sub x control demonstration
Abstract
Babcock Wilcox engineering studies followed by pilot-scale testing has developed/confirmed the potential of utilizing gas, oil or coal reburning as a viable NO{sub x} reduction technology. To date, two US sponsored programs promote natural gas/oil as a reburning fuel because it was believed that gas/oil will provide significantly higher combustion efficiency than using coal at the reburn zone. Although B W has shown that gas/oil reburning will play a role in reducing NO{sub x} emissions from cyclone boilers, B W coal reburning research has also shown that coal as a reburning fuel performs nearly as well as gas/oil without deleterious effects on combustion efficiency. This means that boilers using reburning for NO, control can maintain 100% coal usage instead of switching to 20% gas/oil for reburning. As a result of the B W performed coal reburning research, the technology has advanced to the point which it is now ready for demonstration on a commercial scale.

A Program Opportunity Notice (PON) was issued by the Department of Energy (DOE) in February 1988, soliciting proposals to demonstrate technologies capable of being commercialized in the 1990's that are more cost effective than current technologies and capable of achieving significant reduction of sulfur dioxide (SO{sub 2}) and/or nitrogen oxides (NO{sub x}) emissions from existing coal burning facilities. One of the proposals selected is the Babcox Wilcox Company (B W) project that will demonstrate an innovative technology to reduce nitrogen oxide emissions from coal-fired cyclone boilers. This technology consists of burning a portion of the coal fuel in an oxygen-deficientmore »

Coal reburning for cyclone boiler NO[sub x] control demonstration
The Coal Reburning for cyclone Boiler No. Control Demonstration project progress for April, May, and June 1992 is identified in this ninth quarterly report and pertains to the on-going activities of Phase III -- Construction and Start-up and Phase III -- Operation and Disposition. The project involves retrofitting/testing the reburning technology at Wisconsin Power Light's 100 MWe Nelson Dewey Unit No. 2 in Cassville, Wisconsin to determine the commercial applicability of this technology to reduce NO[sub x] emission levels. Under Phase IIB additional tuning of the control system was completed and operation in the full automatic mode was carried outmore » -

Coal reburning for cyclone boiler NO sub x control demonstration
The coal reburning for cyclone boiler NO{sub x} control demonstration project will be carried out at the Nelson Dewey Station Unit No. 2 of Wisconsin Power and Light in Cassville, Wisconsin. Unit No. 2 is small enough (100 MWe) to limit project costs, but large enough to assure that the reburning technology can be successfully applied to the cyclone-fired utility boiler population. As part of the project, B W's 5 million Btu/hr SBS pilot facility will be utilized to duplicate the operating practices of WP L's Nelson Dewey Unit {number sign}2. The coal which is fired at Nelson Dewy willmore »
