The Heat Balance and Efficiency of Steam Boilers

the basis for compiling the heat balance of a steam boiler 6. The Heat Balance Equation Q = Q1 + (Q2 +Q3 + Q4 +Q5 + Q6) where : Q= available heat of burnt fuel 7 Q1= heat absorbed by working fluid Q2 to Q6 = heat losses Dividing both sides by Q and expressing as a %age we get :

Refuse-Fired Boiler Heat Balance - Columbia University

A heat and mass balance of a refuse-fired boiler uses the intrinsic enthalpy, or energy per pound, to analyze the losses and efficiency of a boiler unit. Essentially, we must measure and account for all steam energy output and boiler losses until the physical laws of conservation of mass and energy are satisfied, or balanced.
