Material selection ASTM A192 for Super Heater.
(OP)
Hi to All
I have a question about selection carbon steel for super heater bagasse boiler i have ASTM A192 2" i can use this material?
temp desing: 470 °C
tem operation 380°C
Desing pressure: 375 Psig
Operation presure: 250 Psig
thanks for your helps.

the design temperature gave me the design engineer other conditions it is that the combustion gases are very abrasive due to bagasse ash is not completely burned and in some cases the diesel contains more than 3% of sulfur.
during the inspection I could see a lot of abrasion , looks like a mild sandblasting .
the temperatures of the combustion gases exceed 600 degrees Celsius (heat exchange) an internal condition i explain in my last question.
thanks.

What is the current tube material in the SH? The abrasion could possibly be handled by tube shields. The diesel fuel is used for start-up or is it supplementary fuel during operation? Do you have any wastage from corrosion?

Ok, now the real reason is apparent based on my question of what is currently installed. If you understand that this material will be limited in service life, you probably could get 6-12 months. This is less than desirable but having worked in Power Generation for over 40 years I understand where you are coming from.
