Boiler Corrosion Prevention for Waste & Biomass Boilers

Boiler Corrosion Mechanisms in WtE and Biomass Increasing efficiency of WtE boilers means increasing pressure and temperature inside the boiler tubes. The combination of new fuel types containing higher levels of corrosive agents with these higher temperatures and pressures can lead to material softening.
