Abstract
A laboratory-based program was designed to evaluate candidate alloys for superheaters operating at temperatures substantially higher than currently used in practice for biomass and chemical recovery boilers. However, the data is also applicable to superheaters operating in very corrosive conditions at lower temperatures. Alloys are ranked according to their performance in simulated environments. Application: This paper provides information on the corrosion resistance of alloys that could potentially be used to make superheaters in very advanced biomass and kraft recovery boilers with superheaters steam temperatures much greater than 500°C. Nearly all the alloys would be effective at preventing corrosion of superheaters tubes that operate in more normal conditions for existing boilers.
