Boiler Parts Economzier   

♦ 09CrCuSb was originally used on petroleum cracking process, to against corrosion caused by Sulfur and Chlorine.

♦ Due to its excellent performance, boiler engineers use it as material for economizer in low temperature environment. It is best steel for anti Sulfur and Chlorine low temperature dew point corrosion.  

We have replaced boiler air preheater and economizer for overseas boiler in recent years, which good performance of material for these parts have been adopted.   

1)Enamel coated air preheater 

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 the ash, 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.  

2)ND steel (09CrCuSb) economizer 

09CrCuSb was originally used on petroleum cracking process, to against corrosion caused by Sulfur and Chlorine. Due to its excellent performance, boiler engineers use it as material for economizer in low temperature environment. It is best steel for anti Sulfur and Chlorine low temperature dew point corrosion.
