Boiler Energy Saving Tips | TLV - A Steam Specialist
The operational efficiency of a boiler is an expression of the percentage of heat energy generated from the heat energy input. It can be found using the following formula: (1) Heat output [kJ] = Mass of steam produced [kg] x (Specific enthalpy of steam - Specific enthalpy of feed water) [kJ/kg] (2) Heat input [kJ] = Quantity of fuel used [kg] x
