What Boiler efficiency, APC Heat rate Coal GCV

Question

Accepted Answer

Boiler efficiency, APC Heat rate and Coal GCV are important factors in determining the performance of a boiler.

Boiler efficiency is the ratio of energy output to energy input and is affected by factors such as combustion efficiency, heat transfer efficiency, and radiation losses.
APC Heat rate is the amount of heat energy required to produce a unit of electricity and is affected by factors such as boiler efficiency, steam turbine efficiency, and generator efficiency.
Coal GCV (Gross Calorific Value) is a measure of the heating value of coal and affects the amount of heat energy that can be extracted from the coal.
Improving boiler efficiency and reducing APC Heat rate can lead to significant cost savings and environmental benefits.
Coal with a higher GCV can produce more heat energy per unit of weight and can therefore be more efficient to use in a boiler.
