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 CO2.

Jan 07, 2009· Coal power stations also produce large amounts of SO 2. This usually needs to be removed from the flue gases by fuel gas desulphurisation. Combined SO 2 /NOx removal systems are complex and costly but prices are dropping for lowtomediumsulphur coalfired power stations. Systems are also in development for highsulphur plants.

Pumping requires a power input (for example mechanical or electrical). Process 2s3 – The high pressure liquid enters a boiler where it is heated at constant pressure by an external heat source to become a saturated vapor. Common heat sources for power plant systems are coal, natural gas, or nuclear power.

The first part of the conversion is efficiency of the boiler and combustion. For this example we take 88 % on an HHV basis that is the normal range for a welloptimized power plant. Second part is the steam cycle efficiency. Modern Rankine cycle, adopted in coal fired power plants, have efficiencies that vary from 32 % to 42 %.
