Boiler controls and blowdown

The purpose of boiler blowdown is to control solids in the boiler water. Blowdown protects boiler surfaces from severe scaling or corrosion problems that can result otherwise.

Valve with adjustable stage nozzle, sample valve, and electric actuator for automatically controlled continuous blowdown.

Automatically controlled continuous blowdown to reduce blowdown wastage with a GESTRA conductivity electrode and the continuous blowdown controller. The blowdown line is automatically closed on shut-down of the boiler plant. BAE 210: 175 barg (2540 psig) at 250 %B0C 125 barg (1810 psig) at 400 %B0C BAE 211: 320 barg (4640 psig) at 250 %B0C 292 barg (4235 psig) at 400 %B0C

Especially suited for boilers operating without constant supervision (TRD 604).
