Since the entrained flow bed gasification technology uses liquid slag removal process,the proper-ties of coal ash slags have significant influence on the operating conditions and performance of gasifier.On the basis of analysis on influence mechanism of coal ash slags on gasifier linings,and from the perspective of influence factors of fusion characteristics and viscosity-temperature characteristics of coal ash slags,this pa-per probes into the requirements of entrained flow bed gasification technology on chemical composition of coal ash,and proposes measures and suggestions on determining the operation window of entrained flow bed gasifier,providing theoretical guidance for better designing and improving entrained flow bed gasification tech-nology and expanding coal adaptability.
