A boiler explosion is a ruinous failure of a boiler. Any Boiler explosion results in two major events:
- The steam under pressure is suddenly exposed to much lower pressure i.e. Atmospheric Pressure resulting it to expand to almost 10-15 times expansion of its volume.
The tremendous amount of energy stored in the pressurized boiler water is suddenly released prompting sudden evaporation of 15 to 20% of the water to get converted into Flash steam. This steam also expands to more than 1700 times its original volume causing catastrophic damages.
