Abstract
The use of micro-alloyed (MA) heat resistant alloys in fossil fired systems has been commonplace for nearly 25 years. These materials, alloyed with nitrogen and rare earth elements such as cerium, have been popular upgrades from stainless steels, such as type 309 and 310. Offering the benefits of higher creep-rapture strength with improved hot corrosion resistance, MA grades have been widely utilized for pulverized coal nozzles, fluidized bed combustion systems, tubeshields, etc. This paper provides corrosion data and case histories on the use of this 35Ni-25Cr-1.3Si-Ce-N alloy in more severe combustion environments.
