Free ChatTypical Energy Balance of a Boiler/Heater (before improvements) Energy in fuel enters the boiler (energy input 100 percent). From the boiler 4 percent of heat loss is through radiation and convection 18 percent is in flue gasses and 3 percent is in blowdown. Energy in heating medium (e.g. steam) exits the boiler.

Free ChatThe boiler takes in energy from some form of fuel such as coal natural gas or nuclear fuel to heat water into steam. All but a small fraction of the world's primary energy comes from fuels and about three-quarters of that fuel ends up going into a boiler (the

Free ChatBoiler Efficiency = Heat output / Heat Input X 100. Or Boiler Efficiency = Q X (h2 h1) / (q X GCV) X 100. Where Q = Qty of steam generated. h2 = Enthalpy of steam at output of boiler. h1 = Enthalpy of feed water. Heat Input = q X GCV. q = Fuel Qty. GCV = Gross calorific Value. Below Link can be used to calculate direct boiler efficiency:-
