To achieve the"reduction,resource utilization,and harmless"treatment of local household waste through threads,it is necessary to utilize the existing supercritical circulating fluidized bed boiler and environmental protection facilities of a certain power plant,and use direct co firing to treat Refuse Derived Fuel/Solid Recovered Fuels(RDF/SRF).Research the combustion characteristics of the supercritical circulating fluidized bed boiler,the preparation and characteristics of RDF/SRF,and co firing technology,design a co firing process suitable for the power plant,and analyze the technical and economic feasibility of this solution.The results indicate that the scheme is technically feasible and can achieve the goal of harmless and resourceful disposal of household waste;The total investment of the co firing system(in plant)is 6.249 million yuan.When the RDF to plant price is 70 yuan/t(including tax),the financial evaluation indicators of the in plant investment of this project are reasonable and the economy is high.
