Many operators and engineers report the complexity of understanding and predicting WtE and Biomass boiler corrosion rates. The same plant operating several lines and feeding from the same bunker of mixed waste can report varying corrosion rates between the lines.

This white paper talks about the pros and cons of commonly used corrosion mitigation technologies, featuring:

  • Statistics and Graphs, from boiler OEMs, Prewin and other sources
  • Case Studies
  • Images and Figures, illustrating problems and solutions

You will learn how to:

  • Prevent forced outages and increase plant availability
  • Prevent tube leaks and repairs
  • Choose an appropriate corrosion solution, considering time, costs, and longevity
