Automated Boiler Blowdown Control System Reduces Water & Energy Consumption to Cut Plant Costs
Ideal for Industrial and Commercial Boilers in Chemical Processing, Food/Beverage, HVAC Systems, Pharmaceuticals, Oil/Gas Refining, Pulp/Paper
Irvine, CA-The highly reliable automated Model 61 Boiler Blowdown Control System from Electro-Chemical Devices (ECD) 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.
With its precision accuracy, the automated Model 61 Boiler Blowdown Control System reduces boiler maintenance make-up water consumption and the energy needed to heat it. In comparison to performing blowdown cycles manually, the system offers operational cost advantages by continuously adjusting the blowdown rate to optimize the boiler water's electrolytic conductivity.
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 ECD's precision 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 Proof applications.
The complete Model 61 System includes ECD's CS10 Conductivity Sensor in a rack mounted panel. The system panel features a modular design for easy installation. It includes a sediment trap for easy removal of sludge buildup, sample cooler, temperature gauge, sample control valve and safety relief valve. All wetted materials are constructed of rugged 316 stainless steel. The process connection features a compression fitting of 0.75 inch NPT to accommodate the CS10 Sensor. The system is designed to operate from temperatures of 0-100°C and at a pressure range of 0-75 psig.
The Model 61 System's C22 Controller is a 110/220 Vac line powered, dual input device with one or more 4-20 mA outputs in addition to conductivity (pH, temperature, PID) and up to eight alarm relays as well as timers and logic functions. The C22's 4-20 mA output can be configured as a PID control output. The PID signal modulates a control valve to keep the surface blowdown rate uniformly close to the maximum allowable dissolved solids level, regardless of load conditions.
The Model 61 System comes standard with a NEMA 4X rated T23 transmitter, which is a two wire, 4-20 mA transmitter. For hazardous conditions, the FM- and CSA-approved T-28 Transmitter is an intrinsically safe, explosion-proof two wire 4-20 mA transmitter offering the standard conductivity output.
