Boiler explosion - Wikipedia, the free encyclopedia
Wreck at Rice Hill, Oregon 1912
You know they still run on fossil fuels, not water, right? That's how the water gets hot enough to become steam. Coal is the common one for trains and industrial applications, but you can fuel a steam engine with anything that can heat the water in the boiler. While liquid water can reach only 212'F, steam [water vapor] may be heated indefinitely under pressure and becomes quite dangerous. Remember PV=nRT. Gasoline-fuelled car fires, even racing cars, rarely kill people nearby, but a boiler explosion can, and also cause life-threatening burns to anyone unlucky enough to be anywhere in the vicinity. The boiler of a steam engine requires constant monitoring to ensure that the pressure does not rise above a safe level, and an unskilled or inebriated operator is a downright hazard.
I am personally happy to see a primitive and exceptionally dangerous power plant be laid to rest, and go view steam engines from a safe distance at the three county fair every fall.
