What is Boiler Blowdown ? - Surface Blowdown -

Boiler blowdown is water intentionally wasted from a boiler to avoid concentration of impurities during continuing evaporation of steam. The water is blown out of the boiler with some force by steam pressure within the boiler. Bottom blowdown used with early boilers caused abrupt downward adjustment of boiler water level and was customarily expelled downward to avoid the safety hazard of

Blow-Down Procedure for Marine Boilers – CORPS

Most of the boiler with continuous blowdown automation are fitted with heat recovery systems, i.e. the hot water from the boiler blowdown is first sent to a heat exchanger unit which utilises the heat of the water (e.g. to preheat the feedwater by installing a heat exchanger or heat recovery equipment in the path) before it goes overboard.
