摘要

对超临界机组滑压运行参数的合理选取进行了理论分析。通过对某电厂东方汽轮机有限公司制造的超临界600MW机组在各种工况不同参数的对比试验

得到了机组的最佳滑压运行曲线

有效地降低了汽轮机的热耗率。

Abstract

The reasonable selection of sliding pressure operation parameters for supercritical units has been theoritically analysed.Through comparison and test of different parameters under various operation conditions of the supercritical 600 MW unit manufactured from Dongfang Steam Turbine Works and equipped in one power plant

the optimal sliding pressure operation curve has been obtained.Under the new sliding pressure operation mode

the heat consumption rate of said steam turbine has been effectively reduced

while under load of 360 MW

the effectiveness of energy-saving on said unit is most remarkable.Besides

under load of 300 MW

the optimal main steam pressure in winter season is 15.8 MPa

and that in summer season is 16.6 MPa.
