They might be utilized alone or to supplant a recuperative heat system or to supplant a steam coil. The object is to recover the heat from the boiler flue gas, which expands the thermal proficiency of the boiler by decreasing the helpful heat lost in the flue gas. Stainless Steel Air Preheaters are utilized as a part of expansive boilers found in thermal power stations creating electric force from e.g. fossil powers, biomass or waste.
