METHOD OF OPERATION OF COMBINED CYCLE POWER PLANT WITH COGENERATION AND COMBINED CYCLE POWER PLANT FOR REALISATION OF THIS METHOD

摘要

FIELD: power engineering.;SUBSTANCE: invention relates to power engineering. The method of operation of the combined cycle power plant with cogeneration, in which air is compressed and supplied into a combustion chamber for fuel combustion, and produced exhaust gases are expanded, in a single turbine, doing the work, and in which exhaust gases leaving the turbine are sent via the heat-recuperating steam generator for steam generation, besides, some incoming air for combustion is sent via the turbine into the heat-recuperating steam generator without participation in process of fuel combustion in the gas turbine, and this part of air for combustion is used to operation of an auxiliary boiler in the heat-recuperating steam generator. Also the power plant is presented for method realisation.;EFFECT: invention makes it possible to provide for high yield of thermal energy and reduced power production without extreme increase of dangerous substances emissions in exhaust gases.;15 cl, 3 dwg
