Customized size rotating air preheater with hot end and cold end heating elements

High efficient Power Station Boiler Rotary Air preheater 

Description 

Rotary Air preheater recovers the heat from the flue gas and transfers the same to the combustion air to the boiler thus reducing the fuel consumption of the boiler.

The efficiency of Rotary Air preheater is very high compared to the Tubular air preheater.                        

Air preheater rotor is divided into compartments in which the heating elements are packed. Heating elements in the Air preheater plays a major role for the heat transfer from the flue gas to the combustion air.
