recuperative furnace
Quick Summary
A recuperative furnace is a type of industrial furnace where flue gases continuously exchange heat with the incoming combustible mixture through metal or ceramic partitions. This process improves combustion efficiency by preheating the incoming mixture. Recuperative furnaces are distinct from regenerative furnaces, which use cycles of heating checker-brick arrangements, and reverberatory furnaces, where fuel is not in direct contact with the material being heated. Thermal-heat recovery, in general, involves utilizing waste heat from industrial processes to reduce overall energy consumption and fossil fuel use.123
