Coal Steam Boiler Thermal Efficiency 103

Efficiency of Thermal Power Plants. - Bright Hub Engineering

This brings the overall efficiency of the power plant to around 33.5 %. This means we get only 1.9 kwhr of electrical energy from one kg of coal instead of the 5.56 kwhr that is theoretically available in the coal. The efficiency or inefficiency of power plants is something that we have to live with for the present till technology finds away out.

FOR POWER GENERATION

Boiler efficiency is sensitive to the moisture content of fuel and to the amount of excess air required. For success­ ful boiler operation, the excess air should be kept above 50 percent. With a RDF heating value varying from 4800 to 7000 Btu/lb (11,162 to 16,278 kJ/kg), boiler ef­ ficiency may range from 70 to 75 percent. CURRENT STATUS OF THE
