Industrial Boiler Air Preheater With Enameled Tube Carbon Steel Material

Introduction
Counted on our professional knowledge, we cater to the needs from customers in renovation and modernization of their exsiting boilers. We have undertaken boiler air preheater and economzier replacement service for many years.

Low temperature corrosion and ash fouling exists for boiler air preheater, especially if burning coal with high sulfur content. The users have to replace the parts or stop the machine to clean theash, which takes cost for users. We adopted the enamel coated air preheater, which has the function of anti-corrosion, wear resistance, anti-ash fouling, and long service life.

We provide solution to the above problem by developing enameled spiral grooved tube air preheater.
