Abstract

Abstract: After the four N100-90/535 condensing steam turbines of Huadian Energy Mudanjiang Second Power Plant had been reformed into heat supplying steam turbines, some problems, such as the overtemperature of 7th section steam extraction and evaporation of feed pump, occurred. The faults reasons were found by using the experimental method. The unit operation mode was regulated; concrete preventive measures were formulated. So the difficult problems influencing on unit security and economic efficiency were solved.

Key words: heat supplying steam turbine, security, economical efficiency, piping over-temperature, evaporation of feed pump
