Waste Heat Recovery Systems for Steam Boilers

An Air Preheater (APH) is an important Boiler auxiliary which primarily preheats the combustion air for rapid and efficient combustion in the furnace with the primary objective of increasing the thermal efficiency of the process. The purpose of the air preheater is to recover the waste heat from the outgoing boiler flue gas and transfers the same to the combustion air, which increases the thermal efficiency of the boiler.
