How much fuel required for 1TPH boiler? - Quora

Mar 10, 2018· Answer Wiki. As efficiency of furnace is 8590% that means ratio of heat consumed to form steam by heat given by coal is 0.850.90. so find the heat that is given by coal. Then equate that heat that is heat given by coal= (mass of coal)*GCV. You have value of heat and GCV. You will get mass.

Boiler Efficiency: Introduction and Methods of Calculation

Combustion Efficiency. The combustion efficiency of a boiler is the indication of burners ability to burn fuel. The two parameters which determine the burner efficiency are unburnt fuel quantities in exhaust and excess oxygen levels in the exhaust. As the amount of excess air is increased, the quantity of unburnt fuel in the exhaust decreases.
