Jan 24, 2017 · January 24, 2017. Office of Energy Efficiency & Renewable Energy. Waste Heat Recovery Resource Page. 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 …

Evaporator and Recovery Boiler Energy Efficiency white

Steam or hot air contains a different amount of heat per volume. A medium with a higher temperature than the recovery medium (E.g. inflowing cold air) produce a higher energy saving outcome. Thus, the greater the difference between the incoming and outgoing medium is, the higher will be the energy saving through a waste heat recovery system.

fired heaters/furnaces. In both cases, waste heat recovery can lead to substantial fuel savings. Process heat from steam boilers Recovering waste heat often reduces the need for steam in a plant. Consequently the boiler's fuel consumption is reduced, as are greenhouse gas emissions and the load on the cooling system.
