  2. Air preheater - Wikipedia

    en.wikipedia.org/wiki/Air_preheater

    The purpose of the air preheater is to recover the heat from the boiler flue gas which increases the thermal efficiency of the boiler by reducing the useful heat lost in the flue gas. As a consequence, the flue gases are also conveyed to the flue gas stack (or chimney ) at a lower temperature, allowing simplified design of the conveyance system ...
