FIELD: district heating systems.
SUBSTANCE: boiler room with a hydrosteam turbine characterized by the fact that it includes: a hot water boiler, from which the heated water of the boiler circuit is supplied to the inlet of the hydrosteam turbine and through a three-way valve to the inlet to the heat exchanger of the second stage of heating the network water; a hydro-steam turbine, which drives an electric generator, from the output of which the steam-water mixture is supplied to the separator; heat exchanger of the first stage of heating the network water, heated by steam coming from the separator of the hydro-steam turbine; a condensate pump that supplies condensate from the separator to the inlet of the boiler circuit pump, which supplies water to the inlet of the hot water boiler, whereas network water is sequentially supplied to the heat exchangers of the first and second heating stages, and a three-way valve is connected to a bypass pipeline through which the boiler water flow can partially or be completely redirected to the bypass of the heat exchanger of the second heating stage to the inlet of the boiler circuit pump.
EFFECT: stable power of the hydro-steam turbine, independent of the temperature of the network water.
