Research on Complex Multi-pollutants Control Technology in a Large-scale Coal-fired Power Plant

摘要

The combined Selective-Catalyst-Reduction and Multi-Circulating-Fluid-Bed (SCR-MCFB) technology was investigated on a 300 MW boiler in a coal-fired power plant. The influence of this combined technology on the efficiency of dust collection,desulphurization, and denitrification, especially the interaction and the match of each system, was studied in order to improve the performance of the flue gas cleaning systems. Meanwhile, the ability on removing mercury of this combined system was studied with Ontario-Hydro (OH) method. The experimental results showed that the combined SCR-MCFB technology can remove not only SO2, NOx and dust hut also mercury in the flue gas with high efficiency.
