Boiler explosions are of a particular danger in (locomotive-type) fire tube boilers because the top of the firebox (crown sheet) must be covered with some amount of water at all times; or the heat of the fire can weaken the crown sheet or crown stays to the point of failure, even at normal working pressure.
The separated steam flows through the overhead pipe (5) and the steam-water mixture flows through the collector pipe (3) to the drum (6) as well. In the drum occurs the final separation of steam from steam water mixture. The rest amount of water flows through the unheated return tubes (1) and downcomers (7) to the rear wall distributor/header (2).

David Holmes, co-founder of Explainer Music and a graduate of Studio 20, a New York University graduate program, used data collected by the investigative journalism group ProPublica to write "My Water's On Fire Tonight". Described by Studio 20 as an "explainer", it is a mini-documentary reflective ...
Diagramatic section through an earlier steam locomotive boiler and firebox to the right. Note the boiler is not fitted with a superheater. In the standard steam locomotive fire-tube boiler, the firebox is surrounded by water space on five sides. The bottom of the firebox is open to atmospheric pressure, but covered by fire grates (solid fuel ...

A blowback (also blow back or blow-back) is a failure of a steam locomotive, which can be catastrophic.. One type of blowback is caused when atmospheric air blows down the locomotive's chimney, causing the flow of hot gases through the boiler tubes to be reversed, with the fire itself being blown through the firehole onto the footplate, with potentially serious consequences for the crew.
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.
A fireman, stoker or boilerman is a person who tends the fire for the running of a boiler, heating a building, or powering a steam engine. Much of the job is hard physical labor, such as shoveling fuel, typically coal , into the boiler's firebox. [ 1 ]
