Description:
A study has been undertaken to investigate the effect of blending PRB coal with an Eastern bituminous coal on the speciation of Hg across an SCR catalyst. In this project, a pilot-scale (1.2 MWt) coal combustor equipped with an SCR reactor for NOx control was used for evaluating the effect of coal blending on improving Hg oxidation across an SCR catalyst. Several parameters such as the ratio of PRB-bituminous coal blend and the concentrations of hydrogen halides (HCl, HBr, and HF) and halogens (Ch and Br2) in the flue gas were evaluated to determine their effects on the oxidation of HgO under typical SCR NOx emission control conditions. The objective of this project was to evaluate the effectiveness of firing PRB-bituminous coal blends to enhance mercury oxidation in a coal fired power plant equipped with an SCR system.
