May 29, 2008 · The qreatest fear in steam is a boiler explosion. That happens when all the water is gone, and the boiler overheats and blows. More pressure is created than the safety valves can release before the boiler ruptures violently. It was a big problem in the early days, taking out buildings, steamboats, probably even locomotives.

The nominal pressure of the steam would bear the same relation to its explosive force, as the ordinary atmospheric 2 9 * 342,Mechanics, lahysics, and Chemistry. pressure bears to its tempest force, since the explosive force of water i s somewhat analogous to that of gunpowder, and the power of each i~ measured by the elastic expansion of the gases produced.

Feb 02, 2016 · The power of all of that steam pressure being released almost instantaneously during a boiler explosion is equal to that caused by detonating explosives or gunpowder. The corresponding shock wave from such a blast can be tremendous. Various estimates of the energy released from a boiler explosion have been submitted over the years.

Steam Explosions There are two major types of boiler explosions: those that occur due to pressure, and those that occur due to a fuel leak. In pressure explosions, the rupture is caused by the build-up of high-pressure steam. The pressure of this steam eventually overloads the boiler and causes it to explode, often with violent force.

A Boiler: The Explosive Potential of a Bomb

A common cause of explosion is the runaway firing condition that takes place when the boilers burner does not shut off. In this case, when the hot-water heater is connected to the city water supply on one side and the building hot-water service on the other, the check valve will shut off and no back pressure will go into the city side.

Steam Explosion and TNT equivalance - Mechanical

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. Corrosion along the edges of lap joints was a common cause of early boiler explosions. The second kind is a fuel/air
