Getting to the Bottom of the Boiler Blowdown Procedure
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 showering hot water on nearby individuals. Surface blowdown …

The Importance of Industrial Steam Boiler Blowdowns - Food
Dec 15, 2010 · Without a 'boiler blowdown', the water in the boiler would soon become a thick muddy soup. What boiler blowdown does is discharge a certain volume of this 'concentrated' water. This is then immediately and automatically replaced by the same volume of fresh boiler feedwater, which will …

Intermittent (Bottom) Blowdown in Steam Boilers
However, if the boiler design and system conditions do not comply with these regulations, an extra cooling system may be needed in the blowdown tank. The main effects on the blowdown rate are: - Boiler Pressure - Blowdown Line Size - Length of the blowdown line between the boiler and the blowdown tank. In practice, a reasonable blowdown …
