All steam boilers must be regularly blown down to reduce the concentration of suspended and dissolved solids in the boiler water.
As this waste is under pressure and at extreme temperature there must be a safe means of storage and cooling (to below 43 degrees C) before discharging to general drainage. The CEA’s BG03 gives full details of safety requirements for blowdown vessels.
As boiler manufacturers, Byworth applies the same exacting standards to their blowdown tank range as they do to their boilers. Designed and built to PD5500, the blowdown vessels are inspected by Lloyds register during manufacture, and are available either from stock or individually built.
The standard range of blowdown vessels sizes cover boiler outputs from 250 to 18000 kgs/hour. For larger outputs, Byworth can design and manufacture blowdown tanks to suit.
