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
Automatic blowdown/continuous heat recovery system: This system allows the boiler to blowdown only when makeup water is flowing to the boiler, thereby transferring the maximum amount of heat possible from the blowdown to the makeup water. No flash tank is generally needed as the blowdown discharged is close to the temperature of the makeup water.
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

NJ joined 8 states in a goal to have electric heat pumps provide two-thirds of all residential heating, air conditioning and water heating by 2030.
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.
