The analysis was verified by comparison with one (the only available) case of instability in a natural gas-fired utility boiler. The writer is aware of at least one case where combustion instability is currently limiting NO reduction in an oil-fired utility boiler to levels higher X than current regulation.

Tube Failures in High Pressure Boilers - Bright Hub

2021-2-27 · There are twenty-two primary reasons for tube failures in a boiler, which can be classified under six major groups. They can be analyzed and corrective and preventive action can taken. Good operating and maintenance practice reduces tube failures. Tube failures during the initial operation period, the normal operation period, and after ten to fifteen years operation show different trends.

The maximum metal temperature within the waterwall tubes is kept within the design conditions, which depend on the saturation steam temperatures and the heat flux. Waterwall tube metal temperatures for utility boilers are usually in the 425 °C range. However, when the balance is upset, the temperature can increase dramatically.
