Beschreibung
Zusammenfassung:	The invention relates to the technical field of fire coal energy conservation, in particular to a steam turbine circulating cooling water recycling device which comprises an air preheater and an air heater, the air heater is arranged in an air inlet channel of the air preheater, an air outlet pipeline of the air preheater is communicated with a boiler flue, and the air heater is installed on a steam turbine circulating cooling water pipeline. Inlet steam turbine circulating cooling water flows into the air heater through the steam turbine circulating cooling water pipeline to release heat and then is led out of the air heater, and the led-out steam turbine circulating cooling water flows into the cooling tower through the steam turbine circulating cooling water pipeline. Cold air entering the air preheater is heated through circulating cooling water of the steam turbine, on one hand, the temperature of hot air entering the boiler is increased, the combustion stability and pulverized coal burnout performance i
