Boiler blow down tanks enable elimination of contaminated condensate
from within the boiler. All of the dissolved impurities
within the water and from the piping system eventually precipitate out
in the form of rust and scale which will eventually contribute to
component wear and reduce heat transfer efficiency. In addition, keeping the
water properly treated is more difficult (expensive) when the water
contains a high level of contaminates.
A blow down tank
enables safe collection of flashed steam and condensate. Whereas a
flash tank is
used to extract low pressure steam and reclaim condensate for reuse,
blow down tanks are designed to enable extraction or venting of low
pressure steam through an
exhaust head and discharge of the contaminated condensate
once it has cooled sufficiently.
Our blow down tanks direct condensate below the retention level of the
tank, allowing cooler water remaining from earlier blow downs to drain
first. The tanks are designed in accordance with ASME Code Section
VIII, Div. 1 and can be ASME Code Stamped. We can also supply the
sealing and blow down drain valves.
