Blow-Down Valve
Blow-Down Valves are used to remove impurities from boiler water. The water is blown out of the boiler with force by the steam pressure within the boiler. It needs to be blown out at speed, so that solid impurities in boiler feed water are carried out with it. These concentrated solids would cause many problems such as reduction of heat transfer, the corrosion of boilers and piping, increased fuel consumption and the need for additional chemical treatment. Thus the removal of impurities is important for maintaining boiler integrity and efficiency.
