【Abstract】 The operational situation and troublesome problems existing in equipment and system for home-made 300MW turbine unit No.3 of imported type after putting into operation at Shihong Power Plant have been briefly described, and the retrofitting measures for perfection of said unit and practical results after implementation of technical retroffitting being expounded. Through said retroffitting, the specific heat consumption has been relatively reduced by 333.45 kJ/(kWh), specific coal consumption for electric energy generation by 12.5 g/(kWh), having obvious retrofitting effectiveness.更多还原
