By the operational fluid which had vapor-liquid equilibrium the generation of electricity method

摘要

PURPOSE: To enhance an efficiency of generation by utilizing that a condensing temperature is varied in the step of condensing operating fluid having gas/liquid equilibrium under a constant pressure. ;CONSTITUTION: Exhaust gas of;a vapor turbine 12 is passed in series through a high temperature condenser (HC) 20, an intermediate temperature condenser 60 and a low temperature condenser (LC) 40 to constitute a condensing system. The HC 20 is operated at a high pressure side, part of turbine exhaust gas in which operating fluid having gas-liquid equilibrium flows is condensed by operating the HC 20 at a high pressure side, and two-operating fluid refrigerant is evaporated. The evaporated refrigerant is transferred to a condenser 30 to be operated at a high pressure side to be condensed, condensed liquid of the condenser is supplied to the LC 40, the LC 40 is operated at a low pressure side, and uncondensed vapor to be transferred from the HC 20 is received. Heat is applied to the condensed liquid from the condenser 30 to allow the liquid to be self-condensed, evaporating vapor is transferred to an absorber 50 to be operated at a low pressure side, condensate of the LC 40 is eventually supplied to a boiler 1, and it is electrically generated by a turbine 12.;COPYRIGHT: (C)1994,JPO
