SYSTEM FOR PREHEATING BOILER FEEDWATER AND COOLING CONDENSER WATER

摘要

A system for pre-heating boiler feedwater and cooling condenser water includes a boiler, a turbine, a turbine condenser, a heat pump, a first heat exchanger, a second heat exchanger, and an expansion valve. A water stream is heated by the boiler into a high pressure steam. The high pressure steam passes through the turbine and into the turbine condenser, converting the steam into condensate. The condensate is passed through a heat receiving side of the first heat exchanger. A refrigerant stream is pressurized by the heat pump and is thereby heated. The refrigerant stream passes through a heat dissipating side of the first heat exchanger, heating the condensate. The refrigerant stream is then depressurized and cooled, and passes through a heat receiving side of the second heat exchanger. A condenser water stream passes through a heat dissipating side of the second heat exchanger, cooling and entering the turbine condenser.

1. A system for pre-heating condensate comprising:
a boiler; a turbine; a turbine condenser; a heat pump; and a first heat exchanger, wherein a first fluid is heated by the boiler into a high pressure steam, wherein the high pressure steam passes through the turbine and into the turbine condenser and is converted into a condensate, wherein the condensate is passed through a heat receiving side of the first heat exchanger, and a second fluid is pressurized and thereby heated by the heat pump and passes through a heat dissipating side of the first heat exchanger, thereby heating the condensate.
