The beneficial effects of the utility model are, utilize high-temperature steam to drive heat pump to extract the heat of condenser recirculated water, heating condenser condensed water, as boiler feedwater, can reduce gross coal consumption rate, reduce condenser recirculated cooling water fluid loss, accomplish low-carbon (LC), green, environmental protection, low power consuming.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in the figure, a kind of coal-fired station bootstrap system, comprise steam turbine 1, condenser 2, also comprise steam drive heat pump 3, the steam drive entrance 6 of steam drive heat pump 3 is connected with steam turbine 1 steam (vapor) outlet, steam drive heat pump 3 clear water side entrance 7 to be exported with the condensate water of condenser 2 by condensate pump 4 and is connected, clear water side outlet and the steam drive of steam drive heat pump 3 are connected with boiler water supply pipeline 8 after exporting and being connected, the thermal source inlet 9 of steam drive heat pump 3 is connected with the high temperature circulation water out 10 of condenser 2 by cooling water circulating pump 5, the thermal source outlet 11 of steam drive heat pump 3 is connected with the low-temperature circulating water inlet 12 of condenser 2.
During application, from steam turbine 1, extract high-temperature steam out drive steam drive heat pump 3, the condensate water that the heat heat-setting water pump 4 that steam drive heat pump 3 extracts condenser 2 recirculated water exports, be i.e. boiler feedwater.The condensate water driving steam condensation Cheng Shuihou and condensate pump 4 to export rises to mix and is input in boiler by boiler feedwater pipeline, the high temperature circulation water of condenser 2 is squeezed into steam drive heat pump 3 thermal source inlet by cooling water circulating pump 5, and the low-temperature circulating water after heat release cooling returns condenser 2 and continues to absorb heat into high temperature circulation water.
Described steam drive heat 3 pump adopts absorption heat pump, centrifugal heat pump or screw type heat pump.
