ANALYSIS OF COAL COAL BASED THERMAL POWER PLANTSFlue gas desulfurization Power Plants
Dec 12 32 The objective of proximate analysis indicates the percentage by weight of the Fixed Carbon Volatiles Ash and Moisture Content in coal The amounts of fixed carbon and volatile combustible matter directly contribute to the heating value of coal Fixed carbon acts as a main heat generator during burningOct 04 32 Flue gas desulfurization FGD is a technology used to remove sulfur dioxide SO 2 from the exhaust flue gases of fossil fuel power plantsFossil fuel power plants burn coal or oil to produce steam for steam turbines which in turn drive electricity generators Sulfur dioxide is one of the elements forming acid rain

Avoiding Clinker Formation in Thermal Power Plant BoilersWet vs dry bottom ash handling compared one plant s
Clinker formation is a serious problem in boilers of thermal power plants which results in forced outage and generation loss Removal of clinkers from the water wall is difficult thus requires pneumatic hammering Low quality coal having less gross calorific value high mineral content high ash content and the over firing of molten slag are causes of clinker formationA multi unit coal fired power station where both dry and wet bottom ash handling systems are employed provides an opportunity for detailed comparison of the two approach Dry systems have significant advantages for bottom ash handling at coal fired power plants with considerable environmental and economic benefits in the case of both new
