  • AUTOMATIC BLOWDOWN CONTROL SYSTEM

    2020-1-21 · The main blowdown valve is fitted at the bottom of the boiler for draining and removing any sludge accumulations from the bottom of the boiler. It should remain in place when the system is fitted and should be manually opened for a few seconds – normally on a daily basis. The system is for limiting the concentration of dissolved and suspended solids in the boiler water and for this purpose the take off point need not to be from the bottom of the boiler. Indeed there are advantages in using a side connection if one exists so that there is less chance of scale entering the blowdown valve. If the bottom connection is used it is necessary to tee off upstream of the main blowdown valve as shown. We recommend that wherever possible the tee is taken off the blowdown …
