Big Horizontal Coal Fired Thermal Boiler Preheater

Corrosion and viscous ash deposition of a rotary air

The corrosion and viscous ash deposition characteristics of a rotary air preheater were investigated. Deposit samples and corroded heat transfer elements were taken from the air preheater of a 300 MW coal-fired power plant in China and analyzed by X-ray fluorescence, X-ray diffraction and scanning electron microscope equipped with energy dispersive X-ray spectroscopy.

Air preheater - Wikipedia

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 and the flue gas stack.
