FIELD: heat power engineering. ^ SUBSTANCE: heat pf windings and of steel of turbine generator is used in cycle of operation of heat power plant and energy of natural gas, supplied to furnace of boiler, is used as well. Method of operation of heat power plant is based upon generation of steam in boiler. For the purpose, natural gas and air are supplied into boiler. Vapor generated in boiler is delivered to turbine which has shaft connected with rotor of turbine generator. Windings and steel of generator are permanently subject to cooling due to circulation of hydrogen through internal space of generator. Hydrogen is cooled in has coolers. Natural gas, delivered to furnace of boiler, is used as cooling medium of gas coolers. Gas is reduced in turbine gas-expansion machine to reach required pressure. ^ EFFECT: improved economical efficiency of heat power plant. ^ 1 dwg |
