Considering different municipal solid waste(MSW)incineration technologies,economic,energy flow and environmental impact analysis for fluidized bed technology,grate furnace,gasification-melting technology and plasma gasification technology was carried out.The results showed that,in the absence of treatment subsidies,the project benefits of fluidized bed incineration technology was best,but the payback period was also required to 9years.To achieve the economic benefits of fluidized bed technology,the subsidies for grate furnace,gasification-melting technology and plasma gasification technology were 70,140,500 yuan/t,respectively.For each MSW incineration technology,the eutrophication and global warming impacts were most significantly,while the human toxic effect was relatively minimal,the environmental impact of gasification-melting technology and plasma gasification technology were far less than that of grate furnace and fluidized bed technology.If considering the pollutant emission reduction benefits,the benefits of fluidized bed incineration technology,grate furnace and gasification-melting technology project would be greatly improved in the current China emission standards,with the emission standards become stricter,the benefits of fluidized bed technology would decrease sharply,and the benefits of gasification and melting technology was best.
