INCREASING THE ENERGY EFFICIENCY OF BOILER AND HEATER ...

Typical 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.

Boiler - Energy Education

The 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

Direct and Indirect efficiency in boilers

Boiler 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:-
