Waste Heat Reduction and Recovery for Improving Furnace .

Heat Losses from Fuel-Fired Heating Equipment. Waste-gas heat losses are unavoidable in the operation of all fuel-fired furnaces, kilns, boilers, ovens, and dry-ers. Air and fuel are mixed and burned to generate heat, and a portion of this heat is transferred to the heating device and its load.

Heat absorbed by water = 0.95 Vs(t 1 − t 2)MJ s −1,. t 1 and t 2 = temperature of hot gases before and after the W.H. boiler, °C.. Total heat as steam = sensible heat in feed water + heat absorbed by water in boiler. In good practice t 2, the temperature at which the flue gases leave the boiler, may be reduced to ca.50 K above the temperature of the water in the boiler.

Waste Heat Recovery Resource Page | Department of Ener

It is estimated that between 20 to 50% of industrial energy input is lost as waste heat in the form of hot exhaust gases, cooling water, and heat lost from hot equipment surfaces and heated products. As the industrial sector continues efforts to improve its energy efficiency, recovering waste heat losses generate cost savings, reduces environmental impact, and improves work flow and productivity.
