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.

The world-class development laboratory at left background featured rigs for component testing at engine operating conditions, including large indirectly fired air preheater to provide heated non-vitiated ( i . e ., full O2 content ) air for combustion testing.

An "'air preheater "'( APH ) is a general term used to describe 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.

Moreover, both the gas ducts and the sealing system of the regenerative air preheater were modernized, resulting in a decrease of air flows from the air section of the preheater to the gas section by 2.5-3 times that leads to a lower rate of own electricity use and a significant increase in the boiler s efficiency.
