Description

Li-for-Energy complex.

ENERGOCOMPLEX The utility model relates to the field of energy and can be used for highly efficient production of electricity. A utility model for a device is known (“Autonomous heat supply system with a hot water boiler, No. 19305 dated 08.20.01 RU). Its disadvantage is that it uses the heat energy of the mains water and reduces its amount allocated to the consumer. In terms of technical nature, the utility model for the device closest to the device in question (Gas Turbine Unit, No. 6837 dated 06.16.98), which contains a gas pipeline, a gas expansion station, a steam boiler, a steam turbine with an electric generator, a gas expansion turbine with an electric generator and other auxiliary equipment of the power station Its disadvantage is that a gas expansion turbine with an electric generator can work only when a steam turbine with an electric generator will work. The purpose of the utility model is to increase the fuel utilization rate in electricity production. The essence of the utility model lies in the fact that the energy complex contains a gas pipeline, a gas expansion station, a steam boiler, steam and gas expansion turbines with electric generators, a steam condenser, a network water heater, and other auxiliary equipment of the power station, and the new one is that to the exhaust gas removal path through pipelines a gas-water heat exchanger is connected in series for utilization of the heat of the exhaust gases, a hot water-working fluid accumulator, a hydro-steam turbine with an electric generator Ator and a condenser-heater, wherein the further gas line connected gas turbine, wherein heat of exhaust gases is used for preheating the natural gas upstream and downstream of the gas expansion turbine. As a result of the presence of these essential features, the device allows the use of low-grade heat of flue gases. A diagram of the proposed device is presented in the drawing. Li-for-Energy Complex

hydro-steam (15) turbines with electric generators, Nara condenser (11), mains water heater (10), natural gas heaters (6,7), pumps (12, 13, 17), hot water accumulator (14), make-up water heater ( 16), heat exchanger-utilizer (4), other auxiliary equipment of the power plant.

The device operates as follows.

The main stream of natural gas enters from the gas pipeline 1 to a gas expansion turbine with an electric generator 2, then to a steam boiler 3, and then through a gas-water heat exchanger-exhaust gas heat exchanger 4 to the atmosphere.

An additional stream of natural gas enters the gas turbine with an electric generator 5. Then, the gas exhausted in the turbine through the natural gas heaters 6, 7 goes into the atmosphere.

The steam from the boiler 3 enters the steam turbine 9, the network water heater 10 and the steam condenser I. By the pumps 12 and 13, the condensate is again pumped into the steam boiler 3.

For the beneficial use of the heat of the gases leaving the steam boiler, a hydro-steam turbine with an electric generator 15 is used, to which a make-up water heater 16, a pump 17, a heat exchanger-utilizer (4) and a hot water accumulator 14 are connected in series.

Thanks to the totality of technical solutions adopted, a high fuel utilization rate is ensured.
