The entire process of electricity production in thermal power plants

: The main production process of thermal power plants (taking coal-fired power plants as an example) is: the raw coal stored in the coal storage farm (or coal storage tank) is sent from coal storage yard to raw coal hopper from boiler by coal transport equipment, then sent to coal crusher by coal feeder to be crushed into pulverized coal. The pulverized coal is sent to the separator for separation, and the qualified pulverized coal is sent to the pulverized coal bin for storage (storage boiler). The pulverized coal in the pulverized coal bunker is sent to the burner of the boiler body from the pulverizer and is pulverized from the burner into the furnace for combustion (direct blown boilers separate the pulverized coal and send it directly to the furnace) . Burning pulverized coal releases a large amount of energythermal power to heat water in water-cooled wall tubes around the furnace and form a steam-water mixture. The mixture is separated by the steam-water separator in the boiler drum. The separated water is sent to the water-cooled wall tube through the downspout for additional heating. The separated steam is sent to the superheater and heated into superheated steam which meets the. specified temperature and pressure. Through the pipe Sent to the steam turbine for work. The superheated steam works in the steam turbine to push the steam turbine to rotate. The steam turbine drives the generator to produce electricity. The three-phase alternating current generated by the generator passes through the wire at the end of the generator and is discharged. to the electrical network via the transformer. The superheated steam which has finished its work in the steam turbine is cooled by the condenser into condensed water. The waterCondensed is sent to the low pressure heater to be heated via the condensing pump, then sent to the deaerator for deoxygenation, and then sent. to the high pressure heater for heating via the feed water pump, sent to the boiler to continue the thermal cycle. The reheating unit adopts intermediate reheating process, that is, the steam after the high pressure cylinder of the steam turbine has done its work is sent to the boiler heater to be reheated, so that the steam temperature is raised to a certain (or initial steam) and then sent to the medium pressure steam turbine. The cylinder continues to operate.
