    engines, the recovery boiler or any biomass reactor is inefficient. The limit to the current steam temperature is limited due to molten salt corrosion on the superheater tubes. The solubility of the protective metal oxide the alloy creates determines the alloy's resistance to molten salt corrosion. y finding a metal oxide with a low solubilityLearn More

  • High Temperature Corrosion in Biomass-Fired Boilers

    Biomass is a "carbon dioxide neutral fuel" and therefore does not contribute to the greenhouse effect. When straw is combusted, potassium chloride and potassium sulphate are present in ash products, which condense on superheater components. This gives rise to specific corrosion problems not previously encountered in coal-fired power plants.Learn More

  • Corrosion Behavior of TP316L of Superheater in Biomass

    Oct 01, 2009 · Traditionally, high- temperature corrosion is not a serious problem in biomass boiler, mainly because the temperature of superheater tubes is not so high. However, the tem- perature of superheated steam will be raised in order to improve the efficiency of biomass boiler. The corrosion during biomass combustion is mostly related to chlorine [5].Learn More

  • Superheater Corrosion Prevention | Jansen Combustion and

    Firing boilers at higher rates has, in some cases, led to higher final steam temperature and excessive superheater metal temperatures, which can accelerate corrosive metal loss.
