Air preheater, or boiler preheater, is an important boiler part. It can be divided into two kinds, Tubular type air preheater and Vertical type air preheater.
Air preheater pipe type, mainly using industrial furnaces or smoke waste heat boiler combustion air preheating furnace enter, such not only improves the thermal efficiency of the stove and reduce the environment pollution.
Product advantages
1.High corrosion resistance property;
2.Small covering area;
3.Pipe and tube plate in every link between separated, the heated bilges cold heat distortion is not bound to avoid stress destruction;
4.Single pipe, tube single or parts of equipment failure does not affect the heat normal operation, two fluid were heat tube, can go outside fin
