Boiler explosion - Wikipedia
A boiler explosion is a catastrophic failure of a boiler . As seen today, boiler explosions are of two kinds. One kind 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, Boiler explosions are of a particular danger in (locomotive-type) fire tube
