FIELD: machine engineering.
SUBSTANCE: claimed plant can operate with various steam-gas plants providing constant or cyclic delivery at the outlet of the vapour-gas mixture. The steam generator can be used both in the composition of the power plants and separately. According to the second technical solution, the working medium participating in the operation of the multi-section expansion machine is formed by combusting fuel and mixing the combustion products with steam from liquid heated in the steam generator mounted in the combustion chamber. By controlling the process of forming the vapour-gas mixture by the controller, it is possible to obtain the working medium in the combustion chamber with different parameters, including with different temperature which is not lower than dew point. In the power plant, the working medium from the steam generator is continuously or cyclically discharged into the receiver of the steam-gas mixture and then supplied to the multi-section expansion machine, where it is expanded to maximum by rotating the power take-off shaft. The last section of the multi-section expansion machine functions as a vacuum pump and the remaining condensate with combustion products is collected in reservoir for collecting condensate, and the remaining combustion products of the fuel are collected at service stations.
EFFECT: increased thermodynamic efficiency of the power plant and the steam generator by reducing losses of heat energy of the burnt fuel discharged outside through the cooling system and with exhaust gases.
