How Does a Coal Power Plant Work? Bright

Thermalbased power plants can produce electricity from coal or other fuel sources The coalfired process requires three different steps to turn energy released from burning coal to generating electricity for consumption Coal fired power plants, while producing power, require a lot of water and produce a lot of pollutants like ash and CO2As shown in the fig1 the thermal power plant has the following area operations: A Coal Handling Plant Coal transported to the plant by the rail line and carrier trucks This coal is transfer from the underground bunker to crusher by series of conveyer belt In coal crusher coal size reduced up to ¾” after that coal transfer to the boiler Hazards Identification and Risk Assessment in Thermal 01082011 Pulverizers prepare raw fuel by grinding it to a desired fineness and mixing it with the just the right amount of air before sending the mixture to Pulverizers 101: Part I POWER Magazine
