Definitions
- the device relates to the field of energy and can be used to produce electricity and heat using combined fuel.
- the disadvantage of this device is the need for additional energy costs to produce hydrogen, as well as the presence of large containers for storing explosive hydrogen.
- Closest to the technical nature of the claimed device is the generating complex according to RU patent for utility model JV2 54631 dated 06/08/2005, which contains a steam boiler, an NgOg steam generator playing the role of a high-temperature hydrogen superheater (VVGSh), a steam turbine with an electric generator and a condenser, the production of oxygen and hydrogen (installation for steam conversion of natural gas to hydrogen) with a recovery boiler, the steam from which is fed to the intermediate stage of the steam turbine.
- VVGSh high-temperature hydrogen superheater
- the disadvantage of the device according to patent N ° 54631 is the incomplete use of the calorific value of fuel in a steam boiler and high temperature stresses in the mixing chamber after the H 2 ⁇ 2 steam generator of high temperature steam.
- the objective of the invention is to improve the efficiency, efficiency and reliability of the power generating complex.
- the essence of the invention lies in the fact that in the known power generating complex containing a steam boiler, a high-temperature hydrogen superheater (H 2 O 2 -generator) with a mixing chamber, which is connected by pipelines for supplying fuel (hydrogen and oxygen) with a hydrogen production unit (installation for steam conversion of natural gas into hydrogen) and with an oxygen producing plant, as well as a steam turbine with an electric generator and a condenser, a recovery boiler, pipelines and fittings, in it on pipelines
- a high-temperature hydrogen superheater H 2 O 2 -generator
- heat exchangers are installed to which the flue gas pipeline from the steam boiler is connected, and the steam supply pipe from the steam boiler is connected to the mixing chamber after the runway.
- Using the installation for steam conversion of natural gas to hydrogen allows for continuous operation of a steam turbine with a rated power at high initial temperature and pressure.
- the high temperature of water vapor up to 1700 - 1800 K at the entrance to the steam turbine due to the combustion of hydrogen with oxygen in the runway in the steam medium after it leaves the steam boiler ensures the turbine operates in the regimes typical of gas turbines.
- the output of a steam turbine is connected to a steam condenser, providing a pressure significantly lower than atmospheric, which is typical for such turbines. This makes it possible to have an available heat drop triggered in a high-temperature steam turbine, 25-30 percent more than in a gas turbine.
- Preheating of hydrogen fuel increases the efficiency of the complex, and cooling the mixing chamber with steam from a steam boiler increases its reliability.
- the inventive power generating complex (hereinafter referred to as the complex) is presented in the form of a circuit (see figure 1).
- the complex contains a steam boiler 1, installation 2 for steam conversion of natural gas to hydrogen, installation 3 for oxygen production, a high-temperature hydrogen superheater (VVPP) 4, with a mixing chamber 5, steam turbine b with an electric generator and condenser 7, a recovery boiler 8, and a heat exchanger 9 for heating oxygen and a heat exchanger 10 for heating hydrogen.
- VVPP high-temperature hydrogen superheater
- the complex also includes a pipe 11, steam supply from the steam boiler, respectively, to the runway 4 and installation 2, a pipe 12 of steam supply from the steam boiler to the mixing chamber 5, a pipe 13 for supplying exhaust gases from the steam boiler 1 to the heat exchanger 9 of oxygen heating, pipe 14 supply of flue gases from the steam boiler 1 to the heat exchanger 10 for heating hydrogen.
- Pipelines 15, 16 for supplying oxygen and for supplying hydrogen, piping 17 for supplying hydrogen to steam boiler 1, piping 18 for supplying mixed steam to turbine 6, piping 19 for secondary combustion products from unit 2 to utilization boiler 8, piping 20 for supplying BBl JJLl 4 are also connected steam from the recovery boiler 8 to the intermediate stage of the steam turbine b.
- the complex also includes other equipment and fittings.
- the device operates as follows.
- steam is supplied via pipeline 1 1 to BBlJJLl-4 and to installation 2 for steam conversion of natural gas to hydrogen, via pipeline 12 to mixing chamber 5, the resulting hydrogen is fed through pipeline 16 to VVPP 4.
- installation 3 for production oxygen for example, by the method of separation of air, receive oxygen, which is also fed through line 15 to the runway.
- part of the steam enters the runway 4, where oxygen and hydrogen are burned in the medium of water vapor.
- Combustion products - high-temperature water vapor is fed into the mixing chamber 5, where it is mixed with another part of the steam supplied through the pipe 12 from the steam boiler 1, this steam cools the walls of the mixing chamber 5, increasing the reliability of the complex and increasing the temperature steam overheating (without intermediate heat exchange surfaces).
- the mixture of vapors through pipeline 18 enters the steam turbine 6 with an electric generator, generating electricity.
- Secondary products of hydrogen production from installation 2 through a pipe 19 are fed to a recovery boiler 8, the steam from which enters the intermediate stage of the steam turbine 6.
- Oxygen and hydrogen from units 2 and 3 are heated in the heat exchangers 9 and 10 before being fed to the runway 4, respectively installed on the oxygen supply line 15 from the installation 3 in the runway 4 and on the hydrogen supply line 16 from the installation 2 to the runway 4.
- oxygen and hydrogen are heated by the flue gases of the steam boiler 1, which are supplied through pipelines 13 and 14.
- Part of the steam after the steam boiler 1, supplied through a pipe 12 to the mixing chamber 5 cools its walls, reduces thermal stresses and increases reliability. Due to the high temperature of the steam coming after the VVPP 4 to the steam turbine b, the power and efficiency of the turbine installation increase.
- the inventive power generating complex allows for continuous operation of a steam turbine with a rated power at a high initial temperature and pressure.
- the advantage of this device is also that for the generation of steam, ensuring its initial overheating and heating of oxygen and hydrogen coal, fuel oil, alternative fuels and renewable energy sources can be used.
