Blow down Tanks: Steam System Solutions

Steam blow down vessels with ASME code stamp

Blow down tanks manage steam system pressure safely and efficiently, protecting equipment and meeting ASME standards. Designed to handle blow down from boilers, these tanks reduce noise and disperse steam effectively. Whether you’re in power generation or industrial processing, find out how our blow down solutions fit your needs.

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.

Why Use a Blow down Tank?

• Prevents flash steam damage to piping.
• Quiets exhaust.
• Applications: boiler rooms, HVAC, manufacturing.

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 blowdowns 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 blowdown drain valves.
