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.
