The primary purpose of blowdown is to maintain the solids content of boiler water within certain limits. This may be required for specific reasons, such as contamination of the boiler water. In this case, a high blowdown rate is required to eliminate the contaminants as rapidly as possible.
How does a boiler blowdown work?
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.
Why is boiler blowdown so important to be performed regularly?
Blowdown of boiler water at regular intervals keeps the total dissolved solid impurities under the rated limits. The process helps in preventing corrosion as it removes the impurities which accelerate the corrosion process. It helps in preventing scaling of boiler tubes and internal surface.
