Boiler blowdown - Wikipedia

Boiler 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

18/11/2020 · Find the circular pressure gauge, likely marked with red and green zones. Pressure is measured in 'bar', so the needle should be resting in the green zone, between 1 and 1.5 bar when the boiler is off (but boilers do vary, so check your manual). If the needle is below 1, in the red zone, your boiler may have lost water, causing low pressure.
