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.

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 Boiler www.WasteHeatBoiler.com. What is a Waste Heat Boiler?. Waste heat boilers are a special type of boiler that generates steam by removing the heat from a process that would have otherwise been wasted.. Waste heat boilers are therefore able to provide significant reductions in fuel and energy expenses, as well as reduce greenhouse gas emissions.
