Powell Associates, LLC 1915 Aliceanna Street Baltimore, Maryland USA 21231 ABSTRACT Failures of tubes in the lower furnace of recovery boilers can lead to smelt/water explosions. Waterside deposits in boiler tubes raise

: 90KB: 1MB: 1012KB: 3 Failures are catastrophic, thick-lipped failures that initiate from ID cracks that are oriented perpendicular to the direction of the stress. Causes: Tube damage occurs due to the combination of thermal fatigue and corrosion. Corrosion fatigue is influenced by boiler design, water chemistry, boiler water oxygen content, and boiler operation.

The failures of boiler tubes due to fireside corrosion in a waste heat recovery boiler utilizing the exhaust gas of a gas turbine fired with high-speed diesel has been analyzed.

2020-5-1 · 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.
