Prefabricated panel type heating system of the present utility model further is set to: it further comprises some heating plants, and this heating plant carries out heat exchange by the circulation and the plate type heat exchanger of user's circulating pump.
Prefabricated panel type heating system of the present utility model also can be set to: described condenser minimum vacuum is pressed and is 87kPa.
Compared with prior art, the utlity model has following beneficial effect:
1. Steam Turbine is not carried out any transformation and satisfy under the prerequisite of Turbo-generator Set safe operation, the vacuum of suitable reduction condenser, both improved the supply and return water temperature of recirculated cooling water, direct thermal source as prefabricated panel type heating system, partially or completely avoid the cold source energy in thermal power plant, improved the thermal efficiency greatly;
2. improvement expenses is low, and construction period is short, good economy performance, instant effect;
3. compare with existing recirculated cooling water heat energy utilization mode, the preparation of low temperature heating water is power saving or saving steam more, and steam turbine can also be multiple simultaneously;
Low temperature heating water by with the recirculated cooling water heat exchange after indirect heating, can realize the independent regulation of heat supply and generating.But when heating demand was enough big, the low-vacuum-operating mode of similar back pressure unit has been avoided the condensing loss fully, and was the most energy-conservation.
