| Zusammenfassung: | The utility model relates to a thermal power field, concretely relates to a heat recovery system for thermal power factory. Heat recovery system includes boiler (4), steam turbine ultrahigh pressure cylinder (5) that connect gradually according to the steam flow direction, high pressure feed water heater and leading evaporative cooler (1), steam turbine ultrahigh pressure cylinder (5) through high pressure cylinder low pressure extraction steam lines valve (7) and high pressure cylinder high pressure extraction steam lines valve (8) and high pressure feed water heater and/or leading evaporative cooler (1) links to each other. The utility model discloses a performance when a heat recovery system for thermal power factory has improved the performance of unit in wide load range especially at the low -load to the unit has been improved at the wide denitration efficiency who loads especially during the low -load, and the system is simple, the feedwater pressure loss is less, the operation is more nimble.
