Efficiency Formula

Efficiency is a measure of how much work or energy is conserved in a process. In many processes, work or energy is lost, for example as waste heat or vibration. The efficiency is the energy output, divided by the energy input, and expressed as a percentage.

Steam Turbine Efficiency

The efficiency of any turbine or engine can be defined as its ability to convert the input energy into useful output energy which is expressed in the form of the following equation.. Efficiency (ɳ) = Output / Input. An ideal turbine with% efficiency is the one which converts all its input energy into output work without dissipating energy in the form of heat or any other form.

Coal Power

Producing electricity from coal starts when the coal is pulverised in huge mills into a fine powder before it is blown into huge kettles, called boilers. Due to the heat in the boiler, the coal particles combust and burn to generate heat to turn water into steam.
