7/5/2020 · Gross station heat rate =Heat input to the plant / Power generation. =Fuel consumed (MT)X GCV (kcal/kg)of fuel/Power generation/MWH. = (55 X 4500)/100. = 2475 kcal/kwh. Above problem can be solved by converting fuel consumed in kg/hr & power generation in. Kwh, then heat rate can be calculated as, =55 X 1000 X 4500/ (100 X 1000) =2475 kcal/kwh.

Heat rate in the context of power plants can be thought of as the input needed to produce one unit of output. It generally indicates the amount of fuel required to generate one unit of electricity. Performance parameters tracked for any thermal power plant like efficiency, fuel costs, plant load factor, emissions level, etc. are a function of the station heat rate and can be linked directly.
