Recovery Boiler Waterwall Tube Failure Analysis with …

An investigation of a water wall tube rupture in a low pressure, recovery boiler was undertaken to determine why the tube thinned to failure in less than five years of service. The failure mechanism, sulfidation corrosion. is not unusual near the furnace bed but the analysis yielded a number of interesting issues relating to boiler design and fabrication practices.

Just as a chain is no stronger than its weakest link, the failure of a single tube with a value of only a few hundred dollars can easily require the shutdown of a multimillion dollar boiler facility. When you consider that the tube thickness for the pressures commonly associated with many industrial boiler plants is often 0.120", 0.095", or less, it is easy to visualize how easily these tubes
