  • Install an Automatic Blowdown-Control System

    2017-6-3 · With manual control of surface blowdown, there is no way to determine the concentration of dissolved solids in the boiler water, nor the optimal blowdown rate. Operators do not know when to blow down the boiler, or for how long. Likewise, using a fixed rate of blowdown does not take into account changes in makeup and feedwater conditions, or variations in steam demand or condensate return.

  • AUTOMATIC BLOWDOWN CONTROL SYSTEM

    2020-1-21 · The BBC06 system works by periodically opening the blowdown valve in order to purge the pipe work and set up a flow of boiler water past the sensor. To avoid wasteful blowdown especially whilst a boiler is on standby or low load. The period between each purge is automatically related to the steam load by monitoring the time the boiler is firing. The BC700 controller measures the level of TDS (total dissolved solids) of the boiler water. The measured value and the set point in the controller are compared. If it is lower than the set point the blow down valve closes at the end of the purge time (typically 10sec) and remains closed. If it is higher than the set point the controller continues the blow down …
