Preheat combustion air. Waste heat recovery devices (whether regenerative burners or recuperators) placed in the flue gas outlet or exhaust stack can extract a large portion of the thermal energy in flue gases and transfer it to the incoming combustion air. Processes operating above 1,400 F are generally good candidates for combustion air preheating, although it may also be used cost-effectively in
Heat Recovery System Efficiencies The Renewable Energy HubThermal wheel ventilation units can deliver a maximum of 80% efficiency, and typical values can vary between 65 and 75%. Plate heat exchangers offer a maximum efficiency of 80% with normal variations between 55 and 65%. Run around coil systems boast a maximum of 55% with typical values
Types of Large Scale Boiler
Options for Improving the Efficiency of Heat Recovery The de-aerator coil supplies steam for de-aeration and also cools the exhaust gases. The condensate heater preheats the make up water before entering the de-aerator and thus reduces the steam for de-aeration. The heat exchanger option increases the energy recovered from the exhaust gases and also reduces the de-aeration steam.
Jan 24, 2017 · 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 heat losses

Use of waste heat boiler. Use of a waste heatboiler to recover part of the exhaust gas heat is anoption for plants that need a source of steam orhot water. The waste heat boiler is similar to con-ventional boilers with one exception:it is heatedby the exhaust gas stream from a process furnaceinstead of its own burner. Waste heat boilers maybe the answer for plants seeking added steamcapacity.
