Advanced reburning with new process enhancements
- Energy and Environmental Research Corporation, Irvine, CA (United States); and others
Advanced Reburning (AR) is a synergistic integration of reburning and selective non-catalytic reduction (SNCR) which can reduce NO{sub x} emissions by over 85% from boilers and furnaces. Reburning is used to set up conditions which optimize the performance of SNCR including broadening of the temperature window and reduction of ammonia slip. AR has been tested extensively at pilot scale as part of two DOE projects. Recently, two AR improvements have been developed and tested at bench scale: reagent injection into the reburning zone and specific promoters which enhance NO{sub x} control, broaden the SNCR temperature window, and further reduce ammonia slip. The reburning zone reagent injection can be used to eliminate the injection of urea or ammonia SNCR agents thus significantly reducing total capital cost. Alternately, two injection stages can be used to increase NO{sub x} control to 95%. This paper presents the results of pilot and bench scale tests of both the AR and the new process enhancements. Plans for additional development and a full scale field evaluation are discussed.
