空冷机组辅汽供热调峰能力ACC Power Plants Auxiliary Steam Heat Supplement Capability of Peak Load Following

摘要:

该成果重点解决电厂两台空冷机组供热存在的调峰能力不足,对一期两台600 MW湿冷机组及辅助系统运行参数、热用户蒸汽参数、运行方式进行综合分析,确定了该型600 MW汽轮发机组采用一期辅助蒸汽系统供热改造,实现了和二期空冷机组辅汽共同供热,为热用户增加一路补充汽源,替代空冷机组供热,提高全厂运行经济性,消除了空冷机组供热调峰能力不足的难题。

A solution was come up with in this paper to solve weak peak load following capability for two ACC power plants in Haner. Deeply analysis was done for the first project two power plants of 600 MW in Haner. The analysis included operational parameters of turbine and its auxiliary facilities, steam users operational parameters, operation mode. Based on the analysis, auxiliary steam header was used to provide the steam for steam users. This solution achieves two projects jointly steam production. One more steam providing method was added to substitute ACC power plants heat supplement, which would save cost and increase the capability of load following at the same time.
