Accurate boiler blowdown - Plant & Works Engineering

1/4/2014 · Blowdown is essential to control boiler water contamination. As a boiler generates steam, any impurities that are in the boiler feedwater and which do not boil off with the steam will concentrate in the boiler water. As these dissolved and suspended solids become more concentrated, steam bubbles fail to burst as they reach the water surface.
