As part of the US Department of Energy`s (DOE`s) Innovative Clean Coal Technology Program, under Round 2, a project for Full Scale Demonstration of Coal Reburning for Cyclone Boiler Nitrogen Oxide (NO{sub x},) Control was selected. DOE sponsored The Babcock & Wilcox (B&W) Company, with Wisconsin Power & Light (WP&L) as the host utility, to demonstrate coal reburning technology at WP&L`s 110 MW{sub c}, cyclone-fired Unit No.2 at the Nelson Dewey Generating Station in Cassville, Wisconsin. The coal reburning demonstration was justified based on two prior studies. An Electric Power Research Institute (EPRI) and B&W sponsored engineering feasibility study indicated that the majority of cyclone-equipped boilers could successfully apply reburning technology to reduce NO{sub x}, emissions by 50 to 70%. An EPRI/Gas Research Institute (GRI)/B&W pilot-scale evaluation substantiated this conclusion through pilot-scale testing in B&W`s 6 million Btu/hr Small Boiler Simulator. Three different reburning fuels, natural gas, No. 6 oil, and pulverized coal were tested. This work showed that coal as a reburning fuel performs nearly as well as gas/oil without deleterious effects of combustion efficiency. Coal was selected for a full scale demonstration since it is available to all cyclone units and represents the highest level of technical difficulty-in demonstrating the technology.
