COAL-FUELLED ELECTRICITY GENERATING UNIT

Coal is delivered to the facility-by railway wagons, barges or trucks. The coal handling system unloads the coal, stocks. reclaims. crushes and conveys it to storage silos. Coal from the silos is then pulverized to a fine powder and blown into the steam generator, where it is mixed with air and combusted (Q release energy for the generation of steam. The steam generator produces. superheats and reheats steam as it proceeds through the cycle. 

The steam turbine generator converts the thermal energy (enthalpy rise) of the superheated and reheated steam to electrical energy. Steam exhausted from the turbine is condensed to liquid in the condenser. The condensate pumps teed the water through t'he I.p. regenerative Iccdwatcr heaters to a deacrator, Boiler feed pumps move the dcacratcd liquid through the h.p. fccdwater heaters back to the steam generator. 

Forced draught (or draft) fans supply combustion air to the steam generator and the' primary air fans transport pulverized coal into the burners. Induced draught fans remove the flue gases from the furnace and exhaust them through the stack into the atmosphere. 

Cooling water for the condenser is supplied by the circulating water system, which takes the heat removed from the condenser and rejects it to cooling towers or another heat sink such as e cooling lake. river or sea.
