Marten E.B. Records of Steam Boiler Explosions Various volumes, e.g. 1869 at Open Library; 1872 at Open Library; 1875, 1878, 1890 covering explosions in Britain. The National Boiler Insurance Company Laxton, William (1866). "Abstract of Report". The Civil Engineer & Architect's Journal. 29 (February 1st): 39– 40
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.
Boiler explosions are common in sinking ships once the hot boiler touches cold sea water, as the sudden cooling of the hot metal causes it to crack; for instance, when the SS Benlomond was torpedoed by a U-boat, the torpedoes and resulting boiler explosion caused the ship to go down in two minutes, leaving Poon Lim as the only survivor in a ...
The heating and DHW demands usually differ, and since installers will select a boiler to meet the larger demand (which is usually DHW in most homes), it will be oversized for the smaller demand; an oversized boiler will operate less efficiently due to problems such as short cycling and having increased return water temperatures that reduce ...
The concentrated area with high stress works as anode and diluted area works as cathode. At anode, sodium hydroxide attacks the surrounding material and then dissolves the iron of the boiler as sodium ferrate forming rust. This causes embrittlement of boiler parts like rivets, bends and joints, which are under stress.
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.
