Blowdown Tanks

During steam boiler operation, sludge created from salts dissolved in water delivery and that after water evaporation remains in the boiler will deposit on the bottom.
It is very important that the sludge is regularly expelled from the boiler through the bottom drain and that the quantity of salts dissolved in water is kept under control through the surface blowdown.
These discharges occur with high boiler temperature and pressure, and when released in the atmosphere expand immediately generating the so-called “flash” steam.
In certain conditions, this phenomenon may also be very violent and it is, therefore, important that the boiler discharges are conveyed to a specific tank that allows a safe expansion and cooling.
The BDV series tanks are designed for this purpose and can be integrated with recovery systems of flash steam generated by the blowdowns.
