Flash Tanks - High-Pressure Condensate to Flash & Reduce

Designed to 125 PSI. The function of a flash tank is to allow high-pressure condensate to flash and a reduced pressure steam. This reduced pressure steam is then used to supply heat to a “low” pressure supply main. It can also be used to reduce and cool to low-pressure steam before re-introducing it to the boiler or condensate receiver, or discharge directly from the system. The vessels are available in standard volumes from 13 to 180 gallons.

Steam Generator vs. Steam Boiler | Powerhouse

Steam boilers are typically larger pressure vessels capable of providing energy to industrial operations. They accomplish this by boiling water at subcritical pressures with intricate fuel systems. In some jurisdictions, the high pressure and high steam output capability of steam boilers requires a fully certified and licensed operator to be on-site in order to be operated. There are two common designs for a steam boiler: firetube and watertube.
