Air preheater for waste heat recovery

Qingdao HEXIN producs various designs of Plate Air Preheaters, typical designs as below:

 

The basic form of the plate air preheater belongs to the plate heat exchanger. The heat exchange element is made of cold-rolled thin steel plate. The mainstream air preheater form in recent years.

Tube Bundle/Spoiler Air Preheater

Tube bundle/spoiler air preheater is a traditional form of air preheater with mature structure and easy maintenance. Spoilers enhance heat transfer.

Cast iron plate air preheater

The cast iron plate air preheater has excellent anti-dew point corrosion performance, greatly reduces the exhaust gas temperature, significantly improves the efficiency of waste heat recovery, 

and prolongs the operation period. The heat exchange element is a double-sided finned alloy ductile iron plate, which has the characteristics of high heat exchange efficiency, resistance to dew point corrosion and not easy to accumulate dust.
