how does steam power generator work??
Answers
Explanation:
In the steam power plant the pulverised coal is fed into the boiler and it is burnt in the furnace. The water present in the boiler drum changes to high pressure steam. From the boiler the high pressure steam passed to the super heater where it is again heated upto its dryness. This super heated steam strikes the turbine blades with a high speed and the turbine starts rotating at high speed. A generator is attached to the rotor of the turbine and as the turbine rotates it also rotates with the speed of the turbine. The generator converts the mechanical energy of the turbine into electrical energy. After striking on the turbine the steam leaves the turbine and enters into the condenser. The steam gets condensed with the help of cold water from the cooling tower. The condensed water with the feed water enters into the economiser. In the economiser the feed water gets heated up before entering into the boiler. This heating of water increases the efficiency of the boiler. The exhaust gases from the furnace pass through the super heater, economiser and air pre-heater. The heat of this exhaust gases is utilised in the heating of steam in the super heater, feed water in the economiser and air in the air pre-heater. After burning of the coal into the furnace, it is transported to ash handling plant and finally to the ash storage.
Answer:
A stem cycle power plant is operated using the Rakine cycle water enters a boiler where it is heated to create steam. The stem is then sent through a steam turbine that rotates the shaft electricity. The saturated water is then pumped back into the boiler to repeat the process.
