The drawing shows a diagram of the power plant.

Power plant comprises a gas turbine engine with a compressor 1, a combustion chamber 2 and the turbine 3, operating on the vapor-gas mixture, the boiler 4 (private embodiment, the boiler 4 can be made of utilization, i.e., in the form of boiler), feed pump 5, a capacitor 6, made contact and the pump-compressor 7, form the ASAS 11, system 12 heating, vacuum compressor 13, a pneumatic pipes 14, 15, steam pipes 16, 17, 18 pipe drainage water from the condenser 6, line 19 for supplying cooling water to the condenser 6, hydraulic lines 20, 21 and power load 22 in the form of a generator (electric generator). When the compressor 1, a combustion chamber 2, the vacuum pump (vacuum pump) and electric generator are turbogroup.

At the outlet of the turbine 3 turbine engine is connected by a pipe 14 to the first input of the boiler 4, the first output of which is connected to the first input of the capacitor 6. Using pipe 15 of the first output capacitor 6 is connected with the atmosphere through the vacuum compressor 13. The second output capacitor 6 via pipe 18 is connected through a contact-vacuum evaporator 9 and the pump-compressor 7 to the pipe 19 provided with a second input of the capacitor 6. The second output contact of the vacuum evaporator 9 through the pipe 17 is connected to the input of the vacuum compressor 10, the output of which is connected to the first input of the second capacitor 8. The first output of the second capacitor 8 through the hydraulic pipeline 20 through the feed pump 5 saudinet network pump 11, the second input of the second capacitor 8 through pipe 21 are connected respectively with the inlet and outlet of the heat supply system 12, which is the consumer of heat in form of hot water. As a consumer may be urban heating network, chemical production, and so on,

Possible implementation, when the feed pump 5 may be included between the boiler 4 and the combustion chamber 2.

The operation of the power plant is operated as follows.

Atmospheric air enters the compressor 1, which is compressed, and is fed into the combustion chamber 2, which simultaneously injected fuel. In the combustion gas temperature in the combustion chamber 2 increases. Hot gases in the combustion chamber 2 is mixed with the steam coming from the boiler 4 through the steam line 16. The steam-gas mixture from the combustion chamber 2 flows into the turbine 3, which causes the rotation of the turbine 22 and the vacuum compressor 13. In the turbine 3, the pressure and temperature of the gas mixture falls. The outlet pressure of the turbine 3 to the value close to the atmospheric pressure and the temperature of 550-750oC. After the turbine 3 hot gas-vapor mixture enters the boiler 4, where it is cooled to the temperature 130-90oC. After boiler 4 gas-vapor mixture is hliday gas-vapor mixture to a temperature below the temperature (76oC) condensation of water. The cooled and dried exhaust gases are compressed to atmospheric pressure in the vacuum compressor 13 and released into the atmosphere. Water from the first capacitor 6 is fused through the pipeline 18 in the contact-vacuum evaporator 9, from which the steam line 17 vacuum compressor 10 is pumped water vapor. The negative pressure in the contact-vacuum evaporator 9, the vacuum created by the compressor 10, provides evaporation of the water coming in contact vacuum evaporator 9. The process of evaporation in terms of discharging contact-vacuum evaporator 9 is accompanied by a decrease in water temperature. Cold water not evaporated by the pump / blower 7 through the pipeline 19 is injected again in the first capacitor 6 to meet the steam flow. Pairs of contact-vacuum evaporator 9 vacuum compressor 10 is pumped to the second capacitor 8. The temperature and the vapor pressure increases. Thus, the steam temperature can reach after vacuum compressor 10 120-150oC and above. The second capacitor 8 vapor is cooled by heat transfer network water heating system 12 to be pumped through the pipeline network 21 by the pump 11. Network water in the second condensate is aatelny pump 5 is supplied to the boiler 4.

Water coming in contact condenser 6 through the pipe 19 at a given design pressure, has a temperature below 60oC. thus discharged through the pipeline 18, the water temperature is close to or below 70oWith taking into account the fact that the condensing temperature is about 76oC. thus, the water flowing into the boiler 4 after the second capacitor 8 has a temperature of more than 70oC.

Due to the presence of the heat pump (the second capacitor 8, the contact-vacuum evaporator 9 and the vacuum compressor 10) on the pipes 18, 19 are cooled water that can be injected into the first capacitor 6 without heat loss to the environment, provided the heating network water to a temperature of 90-120oWith required city network, as well as the simplified scheme of water treatment of boiler water, chemical water treatment is carried out in the contact-vacuum evaporator and the second capacitor, thereby allowing the rejection of a large number of components of the system of water treatment of boiler water.

The combined cycle plant is considered on the example of the steam in the combustion chamber, however, the input pair can be carried out in a flow-through portion of the turbine, and the setting of the compressor, and also in the time, contains gas turbine engine with a turbine operating on the vapor-gas mixture, the first capacitor having two inputs and two outputs, the first output of the first condenser and the inlet of the gas turbine engine is communicated with the atmosphere, the outlet of the turbine, is connected to the power load connected to the first input of the boiler, the first output of which is communicated with the first inlet of the first capacitor, characterized in that it further comprises a contact-vacuum evaporator provided at the input to the second output of the first capacitor, pump-compressor connected the input to the first output contact of the vacuum evaporator, and output to the second input of the first capacitor, vacuum compressor, a second condenser and feed pump, with vacuum compressor connected input and output, respectively, to the second output contact of the vacuum evaporator and the first input of the second condenser, feed pump installed in the line connecting the first output of the second capacitor through the boiler with a gas turbine engine and the second input and second output of the second capacitor are the input and output units for connection of the consumer.
