文摘A lot of study has been made for the design and defining hot end initial parameters of steem turbine of large thermal power plant at home and abroad. But little study has been performed for the reasonable selection of some cold end parameters of steam turbine. The steam turbine cold end parameters defined in actual engineering project are somewhat unreasonable frequently. This paper describes some opinions for selecting some of the steam turbine cold end parameters, especially that of the turbine design back pressure and low pressure cylinder last stage blade length based on the regional features of meteorological conditions in China in association with the optimization of thermal power plant circulating water system.
