The sudden dispersion and projection of the water in the boiler against the bounding surfaces of the boiler is the great cause of the violence of the results: the dispersion, being caused by the momentary generation of steam throughout the mass of the water, and in its efforts to escape, it carries the water before it, and the combined momentum ...
Etching of damage from a boiler explosion in Newark, New Jersey in 1867 This is a list of steam boiler explosions such as railway locomotive , marine transport (military and civilian), and stationary power:
A steam boiler evaporates liquid water to form steam, or gaseous water, and requires frequent replenishment of boiler feedwater for the continuous production of steam required by most boiler applications. Water is a capable solvent, and will dissolve small amounts of solids from piping and containers including the boiler.
While the traction engine was usually built using its locomotive boiler as its frame, other types of steam road vehicles such as lorries and cars have used a wide range of different boiler types. Road transport pioneers Goldsworthy Gurney and Walter Hancock both used water-tube boilers in their steam carriages around 1830.
The steam collects along the top of the boiler and in the steam dome roughly halfway along the top, where it then flows into the large pipe seen running forward. It is then divided into each side and runs downward in the steam chest (at the rear of the smoke box), where it is then admitted into the cylinders by means of valves.
Boiler water is liquid water within a boiler, or in associated piping, pumps and other equipment, that is intended for evaporation into steam.The term may also be applied to raw water intended for use in boilers, treated boiler feedwater, steam condensate being returned to a boiler, or boiler blowdown being removed from a boiler.
The regulator is placed high in the dome of a boiler, as the best location to avoid priming. Priming is a condition in the boiler of a steam locomotive in which water is carried over into the steam delivery. It may be caused by impurities in the water, which foams up as it boils, or simply too high a water level.
Early Yarrow boilers were not superheated, but with the introduction of steam turbines, there was a demand for increasingly higher steam temperatures. Turbines are not tolerant of liquid water droplets, and superheating avoided the problem of steam condensing in the turbine (or piping leading to the turbine).
