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.
Your boiler is termed Waste Heat Recovery boiler (WHR), and is intended to be supplied as a basic boiler system with pressure and level controls.
