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.
