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.

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.

This general introductory course provides some basic engineering concepts needed to understand how a coalfired power plant works, followed by a general overview of power plant layout and operating principles. All major systems in the power plant will be discussed, from coal handling to the switchyard.
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 %.
