What is Blowdown Valve (BDV) ? - InstrumentationTools

Continuous Blowdown (CBD) valves are designed to operate in continuous open position by releasing water continuously through a blowdown tap near the boiler water surface, thereby maintaining the TDS level in the boiler drum. Continuous Blowdown Valve is an angle type valve with a needle shaped trim in a venturi diffuser.

Recover Heat from Boiler Blowdown Water

continuous water discharge (blow down) of water to manage dissolved solids levels. The blowdown rate can range from less than 1% when using extremely high-quality feed water to greater than 20% in a system with poor-quality feed water. Makeup water contains a substantial percentage of total heat input for the boiler.
