Descriptions:

"An air preheater (APH) is any device designed to heat air before another process (for example, Combustion in a boiler) with the primary objective of increasing the thermal efficiency of the Process. They may be used Alone or to replace a recuperative heat system or to replace a Steam coil.

There are two types of air preheaters for use in steam generators in thermal power stations: One is a tubular Type built into the boiler flue gas ducting, and the other is a regenerative air Preheater.these may be Arranged so the gas flows horizontally or vertically across the axis of rotation.

Another type of air preheater is the regenerator used in iron or glass manufacture."
