【Abstract】 According to real circumstances, the calorific value of municipal solid waste(MSW) in our country is much lower than that of the developed countries. Therefore, circulating fluidized bed(CFB) combustion technology using coal as auxiliary fuel was put forward to the treatment of MSW to decrease operating cost by a big margin. This technology conforms to the situation in our country, and it has some advantages of lower NO x ?SO 2 and dioxins emission. The authors suggest that exhaust gas adopt a combination technique of spraying activated carbon plus bag filter, and flying ash disposal should adopt high temperature melting process.更多还原
