A thermal power station is a power plant in which heat energy is changed over to electric power. Most thermal power plants on the planet the turbine are steam-driven. Water is warmed, transforms into steam and turns a steam turbine which drives an electrical generator. After it goes through the turbine, the steam is consolidated in a condenser and reused to where it was warmed; this is known as a Rankine cycle. The best variety in the plan of warm power stations is because of the distinctive heat sources, petroleum derivative overwhelms here, nuclear hear source and solar based heat sources are additionally utilized. Some like to utilize the term energy center because such facilities change over types of heat energy into electrical energy.Certain thermal power plants additionally are intended to deliver warm vitality for mechanical motivations behind area warming, or desalination of water, and creating electrical power.
In thermal power stations, mechanical power is produced by a heat engine that transforms thermal energy into rotational energy. Most thermal power stations produce steam. The steam produced is used to drive the generators. To produce the steam required a boiler is used. A boiler or steam generator is a device used to create steam.
The boiler used will be of type traveling grate or fluidized bed, depending upon the biomass fuels that are being used. The salient features of the boiler unit include :
- Super heater
- Steam and mud drums
- Air pre-heater
The steam generated from the boiler will drive a steam turbine coupled to an electric generator. The power generated will be evacuated to the nearest substation.Steam from the turbine will be condensed in a condenser and the condensate will be supplied to the de-aerator by means of a condensate extraction pump.
