Boiler blowdown expansion and cooling unit ADCA BEX

The ADCA BEX series blowdown expansion and cooling units are used in modern boiler houses to cool hot waste water and steam boiler blowdown before discharging them into a pit or drain.

OPERATION

The waste water is discharged into the unit, which is at atmospheric pressure, and the cooling water enters through a control valve controlled by a thermostat, mixing it with the hot water.
If flash steam can not be recovered or discharged to atmosphere, an additional condensing water spray system can be supplied. It is fitted into the top of the unit and can be controlled directly, either by another thermostat, or by the same command used for the automatic blowdown valve control.

BEX boiler blowdown expansion and cooling units are designed for handling the short bursts of intermittent blowdown from the steam boiler and other hot water drains.

They allow the flash steam to separate and to vent safely to the atmosphere through the exhaust head.

Cooling water is injected in the vessel bottom but an additional flash steam cooler can be installed for better performance.

For non standard models , please consult.
