Description
Due to the continuous evaporation process in the steam boiler
the density and hence the TDS (= Total Dissolved Solids) concentration of the boiler water is increased. The TDS level must
remain within the limits specified by the boiler manufacturer
and applicable guidelines. For this purpose a certain amount
of boiler water (= boiler blowdown) is discharged continuously
or periodically. The continuous blowdown valves BA... and
BAE... feature specially designed and wear resistant nozzle
stems that enter concentrically into a system of expansion
chambers which are arranged one after the other, making
the valve well suited for the continuous discharge of boiler
blowdown at very high differential pressures. The continuous
blowdown valves BA... and BAE... are suitable for operation
in steam boiler plants according to TRD 604, EN 12952
and EN 12953.
