Failure Investigation of a Fire Tube Boiler Introduction

After 5 years in service a stay bar at the rear end of the boiler failed catastrophically. Upon closer inspection cracks were detected on most of the stay bar joints on the rear end side. Figure 1: Schematic of typical stoker fired fire tube boiler. An investigation was requested to determine the root cause for failure of the stay bar.

Causes for Flame Failure in a Boiler and Operator Action

Maintaining a good flame in a boiler is the key to a good boiler performance. Unstable flame is always a threat for boiler furnace explosion, which can lead to a large outage of boiler and loss. There are many causes that can contribute to boiler flame failure. Hence it has become a practice of all boiler designers to interlock purging the boiler with boiler start-up.
