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.

Cost of boiler tube failures 9/4/2013 Steag O&M Company 7 The cost of boiler tube failures is comprised of three main components; the cost of the repair, the cost of start up oil to return unit to service, and the cost of lost production. A rule of thumb for repair costs of 200000 per day out of service+ cost of material

Tube Failures in High Pressure Boile

Tube Failures in High Pressure Boile

Whatever the type of fuel being fired, all high pressure boilers are bound to have a tube failure during the course of their working life. Did you know that a single tube failure in a 500 MW boiler requiring four days of repair work can result in a loss of more than $1,000,000 apart from the generation loss?

encompassed both fire-tube and water-tube boilers with a further subdivision of water tube boilers into sugar and non-sugar boilers. Although there are only a limited number of fire-tube boilers in use in the sugar industry it was felt that seriousness of the failure mechanisms warrants their inclusion in this paper. The statistics
