The report gives results of the full-scale demonstration of Limestone Injection Multistage Burner (LIMB) technology on the coal-fired, 105 MW, Unit 4 boiler at Ohio Edison's Edgewater Station. Developed as a technology aimed at moderate levels of sulfur dioxide (SO2) and nitrogen oxides (NOx) emissions control for relatively low-cost retrofit applications on older plants, LIMB operation at a calcium to sulfur (Ca/S) molar ratio of 2.0 is shown to be capable of achieving about 55 to 72% SO2 removal. Sorbents tested included a commercial calcitic hydrated lime, both with and without a small amount of calcium lignosulfonate, a material added to improve reactivity. Results are given for humidification of the flue gas both to an 11 C approach to the saturation temperature and for minimal humidification. The performance of the XCL low-NOx burners, with an overall emission of 206 ng/J is also presented. The report also discusses the impact of LIMB technology on boiler and plant operations.
