Automatic Boiler Blowdown Control System

Pilot lights indicate when the drain valve is open or closed and when the boiler is on or off.

Automatic boiler blowdown control system. The model 61 automatic boiler blowdown control system from ecd provides a reliable solution for the continuous control of the surface blowdown rate for commercial and industrial boilers. An electronic unit and timer controls the ball valve and boiler. Automatic surface blowdown control systems maintain water chemistry within acceptable limits while minimizing blowdown and reducing energy losses. An automatic blowdown control system continuously monitors the boiler water adjusts the rate of blowdown and maintains the specific conductance of the boiler water at the desired level.

Blowdown valves bdvs are used to depressurize a system or component in order to carry out maintenance work or if there is an emergency. The basic components of an automatic blowdown control system include a measurement assembly a control center and a modulating blowdown control valve. An automatic blowdown system may be installed on any steam boiler regardless of size or operating duty cycle. Ian sutton in plant design and operations 2015.

The bdvs require a downstream isolation valve with a bleed between the two. Automatic surface blowdown control systems maintain water chemistry within acceptable limits while minimizing blowdown and reducing energy losses. In the case of remedial work once the pressure has been relieved the downstream isolation valve will be closed. An automatic blowdown control system optimizes surface blowdown rates by regulating the volume of water discharged from the boiler in relation to the concentration of dissolved solids present.
