In the event of priming (and also when steam is admitted through cold piping or into a cold cylinder) the operators need to open the cylinder cocks, which are designed to release trapped water. Once occurring, the problem can affect the level indicated in the boiler's gauge glass and for this reason is difficult to put right without reducing ...
Modern boilers are designed with redundant pumps, valves, water level monitors, fuel cutoffs, automated controls, and pressure relief valves. In addition, the construction must adhere to strict engineering guidelines set by the relevant authorities. The NBIC, ASME, and others attempt to ensure safe boiler designs by publishing detailed ...
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 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 fusible plugs, usually located in the highest part of the crown sheet, have a soft metal alloy core which melts out if the water level in the boiler gets too low. Steam and water blowing into the firebox both alerts the locomotive crew to the low water condition and helps put out the fire. Not all locomotives are equipped with fusible plugs.

Boiler feedwater is the water which is supplied to a boiler. The feed water is put into the steam drum from a feed pump. In the steam drum the feed water is then turned into steam from the heat. After the steam is used, it is then dumped to the main condenser. From the condenser, it is then pumped to the deaerated feed tank.
Supercritical water exists at temperatures above 374 °C and pressures above 220 atmospheres. Diagram of a supercritical water-cooled nuclear reactor. A supercritical steam generator is a type of boiler that operates at supercritical pressure and temperature, frequently used in the production of electric power.
