FIELD: power engineering.SUBSTANCE: steam and gas power plant comprises a high-discharge combustion chamber separated into a liquid cavity with a regenerator and a steam and gas cavity with partitions forming a row of chambers, an economiser, a turbine and a generator. The high-discharge combustion chamber is made as combined with a gas turbine unit /GTU/ with the possibility of discharge into its steam and gas cavity of exhaust gases of the GTU via a heat exchanger made in the liquid cavity and via a device for afterburning of fuel made in the steam and gas cavity. At the same time the body of the combustion chamber is made of cylindrical shape with damper cavities arranged between its double-wall cover with spherically convex walls inside the body and outside the body and the bottom. The bottom is made as installed onto shock absorbers with a hollow stand with a compensator connected with the cover. Besides, the hollow stand is made as capable of communication of damper cavities between each other and with the possibility of controlled communication via a compensating device with the steam and gas cavity of the combustion chamber.EFFECT: invention makes it possible to increase efficiency and reliability of a plant in operation.1 dwg |
