METHOD OF WORK combined-cycle power plant AND DEVICE FOR ITS IMPLEMENTATION

摘要

1. A method of operating the steam-gas power plant, comprising compression of air heating it with combustion of fuel in the combustion chamber, expanding the warmed working fluid in the turbine gas generator using mechanical energy obtained for compressing air, heated working fluid in the post-combustion chamber, expanding the working fluid in the power turbine to pressure below atmospheric pressure, cooling the working fluid from its utilization of thermal energy for steam generation and for heating, the expansion of steam produced in the steam turbine, feed its lower part to the combustion chamber. most of this superheat steam being fed into the afterburning chamber from the vapor recovery component aqueous condensate expanded working body with its use in generating steam. compressing the dried working fluid and its release to the atmosphere, the use of mechanical energy of the power turbine to generate electricity and to compress the dried working fluid, characterized in that the cooling of the expanded working fluid after generating steam produced in the heating heat exchanger, and condensing its vapor component is carried out in the contact cooler-condenser due to the injection of the cooling water; a smaller portion of steam produced is expanded in a steam turbine to a pressure exceeding the pressure of compressed air in the combustion chamber is not less than 20%, and its greater part to a pressure exceeding the pressure in the post-combustion chamber is not less than 20%; heat dried compressed working fluid utilized for heating part of the water used to generate the condensate para.2.
