Title:
DOUBLE FLOW TURBINE PLANT
Document Type and Number:
Japanese Patent JPH02181002
Kind Code:
A
Abstract:
PURPOSE:To reduce variation in turbine inputs and eliminate also the drain of cooling water in the title turbine wherein the fluid steam having heat of condensation smaller than that of a water steam is used together with the water steam by recovering the heat of condensation in a condenser through a heat pump system. CONSTITUTION:Each fluid fed from a turbine 1 is condensated in liquid in a condenser 2, then being pressurized in a condensate pump 3, to be thus led in a separator 4. The fluid fed from the separator 4 is pressurized in a liquid feed pump 5 and a water feed pump 6, followed by heating in a fed liquid heater 7 to be evaporated in steam in an evaporator 8. The resultant steam is made to pass through plural auxiliary heaters 9, 10 and then returned to the turbine 1 through a steam mixer 11. Besides, refrigerant fed from a compressor 12 passes through an auxiliary heater 13 and then heats the liquid in the evaporator 8 while being expanded in respective expansion valves 15, 16 to absorb heat in the condenser 2 and respective evaporators 17, 18, followed by returning to the compressor 12 through the auxiliary heater 19. The turbine 1 is directly connected with the compressor 12 by means of an electric motor serving as a generator 20.
