BLOW DOWN TANKS

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.  Keeping the water properly treated is more difficult (expensive) when the water contains a high level of contaminates.

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.

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.
