Boiler Blowdown Control System

The Model 61 Boiler Blowdown Control System offers a complete, ready-to-use system providing continuous control of the surface blowdown rate for commercial and industrial boilers, optimizing blowdown cycles and reducing scaling and corrosion to reduce plant operating costs and extend boiler life. As boilers operate, dissolved solids accumulate in the water.

The Model 61 Boiler Blowdown Control System offers a complete, ready-to-use system providing continuous control of the surface blowdown rate for commercial and industrial boilers, optimizing blowdown cycles and reducing scaling and corrosion to reduce plant operating costs and extend boiler life. As boilers operate, dissolved solids accumulate in the water. When total dissolved solids (TDS) become overly concentrated, they can cause damage to piping, steam traps and other process equipment and form sludge in the boiler. The sludge impairs boiler efficiency and heat transfer capability. To avoid damage from TDS, boiler water must be periodically discharged, or blown down, and replenished with fresh feed water. The Model 61 System calculates TDS levels by measuring conductivity in the boiler water. The conductivity measurement is made using the CS10 Conductivity Sensor, featuring a standard range of 0-10,000 µS or optional ranges of 0-1000 µS or 0-100 µS. Outputs can be configured using the standard T23 transmitter, the optional C22 controller or optional T28 transmitter for Intrinsically Safe (IS) or Explosion.
