Summary:Despite successful demonstrations in the early to mid-1990s, reburning technology for NO(sub)x control has achieved relatively little commercial penetration. The question now is whether reburning will make a comeback or if it has been permanently relegated to niche status. In the 1980s and 1990s, several organizations, including the U.S. Environmental Protection Agency, the Electric Power Research Institute, the Gas Research Institute, and the U.S. Department of Energy (DOE) supported the development of reburning technology on utility-scale coal-fired boilers. The first full-scale demonstration occurred in 1988 at Ohio Edison's Niles Plant, a 108 MW cyclone boiler. The demonstration achieved NO(sub)x reductions of 50%, and reburning was off and running in the U.S. During a recent conference, DOE's National Energy Technology Laboratory revealed a scorecard covering all known reburning applications on utility-scale boilers. Of the 39 rebuming projects listed, 11 are still operating, 10 have been shut down but are still in place, seven have been decommissioned, three are planned, and the status of eight others could not be determined.
