FIELD: power production.
SUBSTANCE: combined heat and power plant is overbuilt with gas turbine plant. Air cooler - steam generator is available in the air duct behind air compressor. The steam generator includes economising, evaporating and steam superheating surfaces. The first stage of economising surface is linked with deaerator at water inlet. At water outlet, it is linked with gas water heater inlet of feed water. The gas water heater outlet is connected with the evaporating surface of the air cooler - steam generator via pipeline. The air cooler - steam generator outlet is linked with high pressure steam line of the combined heat and power plant through the additional steam heater. The low pressure combustion chamber and the second stage high-pressure steam heater are installed in series between the high and low pressure gas turbines. The gas water heater for delivery water from heat supply system is installed in low pressure gas line behind the gas water heater of feed water.
EFFECT: increase of effective power and cycle economy in combined heat and power plant overbuilt with gas turbine plant.
