Modern boilers discharge bottom blowdown to a blowoff tank where the blowdown can flash and vent steam upwards without entraining water which might cause burns. A pipe near the bottom of the blowoff tank maintains a water level below the blowdown entry point and allows cooler water remaining from earlier blowdown events to drain from the tank ...
A blow-down valve mounted at the water-level of a boiler, used to blow down lighter oily or foamy deposits within a boiler that float on the water-level. Sludge another term for mud. Smokebox an enclosed space at the extremity of a fire-tube boiler, where the exhaust gases from the tubes are combined and pass to the flue or chimney. Snifting valve
A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications, [1] [page needed] [2] [page needed] including water heating, central heating, boiler-based power generation, cooking, and sanitation.
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.
blowdown (or blow-off) cocks, which allow water to be ejected from the boiler to avoid concentration of impurities remaining after evaporation of steam. [3]: 8 Whistle Steam powered whistle, located on top of the boiler and used for signalling (by the number and length of notes) and warning of approach. [2] [5] [6]: 247–248 [3]: 96
Blowdown is the controlled removal, safe flow and disposal of vapour from a pressure vessel. [1] Blowdown, or depressurisation, removes hazardous inventory from a vessel, reduces the pressure in the vessel and thereby reduces the stresses in the vessel walls. Blowdown is used prior to draining of a vessel for maintenance.
Sometimes, conductivity measurements are linked with other methods to increase the sensitivity of detection of specific types of ions. For example, in the boiler water technology, the boiler blowdown is continuously monitored for "cation conductivity", which is the conductivity of the water after it has been passed through a cation exchange ...
Blowdown or Blowing down may refer to: Windthrow or forest blowdown, a felling of trees by windstorm; Blowdown stack, a vertical containment structure at a refinery or chemical plant; Blowdown, a process plant controlled or emergency depressurization; Boiler blowdown, a steam-boiler process to remove impurities
