By the operational fluid which had vapor-liquid balance the generation of electricity manner

摘要

PURPOSE: To improve generating efficiency through the generation of a low condensation pressure at a low temperature by a method wherein superheat working fluid produced at a waste heat boiler is guided to a turbine to effect generation and condensate produced by condensing turbine exhaust gas is returned to an exhaust heat boiler. ;CONSTITUTION: Condensate (condensate of working fluid) of a low temperature condenser 40 is caused to flow as working fluid to a waste heat boiler 1 by using high temperature gas serving as a heat source. Generated superheat working fluid is introduced to a steam turbine 12 through a feed route 11 to drive a generator 13. Exhaust gas of a steam turbine 12 is guided to a high temperature condenser 20 operated on the high temperature side and brought into contact with two-working fluid (a refrigerant + an absorbent). A part of turbine exhaust gas is condensed and along with the condensation process, a refrigerant of the two-working fluid is vaporized. After refrigerant steam is condensed by a condenser 30, and fed to a low temperature condenser 40 operated on the low pressure side. A non-condensed vapor heat from a middle temperature condenser 60 is exerted and self-condensed to produce condensate.;COPYRIGHT: (C)1994,JPO
