Objective to study the feasibility and effect of blended fuel combustion in Circulating Fluidized Bed boiler,the process flow of a coal chemical enterprise was optimized.Additional combustible gas from torching system was feed into coal boiler,the relationship between the amount of combustible gas increasing and coal consumption and carbon content of ash and vapor production was investigated.The results of experiment showed that as 4000Nm3/h combustible gas was feed into150t/h boiler,the operation of the system was improved and obvious effects were obtained,coal consumption was reduced 10%,carbon content of ash was reduced 8～12% and vapor production was increased 20%.
