A boiler explosion is a catastrophic failure of a boiler. There are two types of boiler explosions. One type is a failure of the pressure parts of the steam and water sides. There can be many different causes, such as failure of the safety valve, corrosion of critical parts of the boiler, or low water level.
BLEVE–fireball, 2008 Toronto propane explosion The following is a list of boiling liquid expanding vapor explosion (BLEVE) accidents. It shows whether the accident occurred during dangerous goods transportation or at a fixed facility, the accident origin (e.g., storage, process reactor, rail tank car, tank truck), the material involved, its amount, the number of fatalities, and whether a ...
An ERW seam selective corrosion failure in one of the pipelines caused the failure. [147] [202] [203] August 31 – A gas company crew struck and ruptured a fitting on a 4-inch plastic gas main in Green Oaks, Illinois. While the crew was attempting to excavate a nearby valve to shut off the flow of gas, the backhoe struck an unmarked power cable.
A BLEVE–fireball at the Philadelphia Energy Solutions refinery, as rendered by the CSB. A boiling liquid expanding vapor explosion (BLEVE, / ˈ b l ɛ v iː / BLEV-ee) is an explosion caused by the rupture of a vessel containing a pressurized liquid that is or has reached a temperature sufficiently higher than its boiling point at atmospheric pressure.
The tubes must be clean enough to allow passage of the probe: deposits of debris, rust, or scale may have to be removed by chemicals or pressure washing. In water-tube boilers , the tubes may be examined from the outside when the boiler is shut down, often using ultrasonic testing .
The National Board lab supports industry research and development by testing new designs, serving as a comparative standard for other laboratories, validating new concepts, and – upon jurisdiction request – assist in boiler and pressure vessel incident investigations. [4]
The gauge glass on a boiler needs to be inspected periodically and replaced if it is seen to have worn thin in the vicinity of the gland nuts, but a failure in service can still occur. Drivers are expected to carry two or three glass tubes, pre-cut to the required length, together with hemp or rubber seals, to replace the tubes on the road. [1]
