Managing Fuel Supply in Power Plant
Efficiency
First is efficiency of the boiler and combustion and second part is the steam cycle efficiency.
Heat Rate
Heat rate is the heat input required to produce one unit of electricity.
Coal Quantity
Since coal has a heat value of 20,000 kJ/kg, for producing one kw.hr we require (10765 / 20000) 0.538 kg of coal.
