| Abstract: | The process of limestone injection into the furnace for flue gas desulphurization in a 1×350MW coal-fired power plant was rebuilt with limestone-gypsum method.The operation results show that the SO2 removal efficiency is no less than 95% after its rebuilding,and the emission concentration of SO2 is no more than 100 mg/m3 when using common coal as fuel.In the meanwhile,the operation fee can be cut down by several million yuan(RMB) per year.The benefits of environment and economy are realized. |
