摘　　要：提高生活垃圾焚烧锅炉的主蒸汽参数可提高热力系统循环效率。本文基于朗肯循环、理论循环热效率讨论循环热效率与主蒸汽参数的关系,并探讨我国锅炉主蒸汽参数系列的确定,分析提高蒸汽压等级对锅炉运行管理的影响。循环热效率随蒸汽初压增大而提高,实际运行过程中,应充分考虑提高蒸汽压等级对汽水循环倍率、循环系统类型、汽包蓄热能力、锅炉压力部件材质、汽水质量等运行管理过程造成的影响。Increasing the main steam parameters of the domestic waste incineration boiler can improve the cycle efficiency of the thermal system.Based on Rankine cycle and theoretical cycle thermal efficiency,this paper discussed the relationship between cycle thermal efficiency and main steam parameters,and discussed the determination of main steam parameters series of boilers in China,and analyzed the influence of improving steam pressure level on boiler operation management.The thermal efficiency of the steam cycle increases with the increase of the initial pressure of the steam.In the actual operation process,the influence of increasing the steam pressure level on the operation and management process such as steam-water circulation ratio,circulation system type,drum heat storage capacity,boiler pressure component material and steam-water quality should be fully considered.
