The cleaned steel is then exposed to the high temperature flue-gas environment, and an oxide film reforms. The oxide forms by converting steel to scale, and a little metal is lost. Each cycle of scale formation and removal reduces the wall thickness until the boiler tube is too thin to contain the fluid pressure, and failure occurs.

introduction of hydrocarbon material. The investigation determined an in situ zirconium oxide oxygen probe was the source of ignition. These oxygen probes are very common with fired equipment such as boilers. If excessive unburned fuel accumulates from failed light-offs, or if fuel leaked into boiler or hydrocarbons are ingested through fan, it could be
