摘要:

350MW超临界供热汽轮机是目前国内大型供热机组的主导机型,350MW机组是否可进一步提高蒸汽参数,向超超临界参数发展从而进一步提高机组经济性,一直存有争议。本文结合各主机厂的分析结论,针对350MW供热机组采用超超临界参数的技术可行性、初参数选择的合理性以及设备投资与运行成本的经济性比较等方面进行论述分析,对350MW采用超超临界参数的合理选择提供了参考意见。

Abstract:

The 350MW supercritical steam turbine is the main type for domestic large heating unit at present, and there is a constant dispute whether its economy could be improved by increasing steam parameters to ultrasupercritical parameters. Combining the analysis conclusions of turbine plants, this paper analyzed the technical feasibility of 350MW heating unit using ultrasupercritical parameters, the rationality of initial parameters selection and the economy of equipment investment and operation cost. And provided a reference for the reasonable ultrasupercritical parameters selection of 350MW unit.
