Blowdown tanks for steam and hotwater boilers

General information

To maintain the correct conductivity level in the boiler water, the boiler is equipped with a blowdown valve to replace the water in the boiler when the conductivity exceeds the operational limits. The blowdown water will have the same temperature at the saturated steam when leaving the boiler. Water at this temperature will in most cases damage the drain system in the boiler house and create flash steam at the drain, causing a potential hazard to personnel in the area. To prevent this, a blowdown tank can be installed.

The function of the blowdown tank is to mix the blow down water with make up/cooling water, and reach a temperature that is safe for the drain pipes. (Typically 60°C).

Parat blowdown tanks are designed for best possible method to cool the blow down water. This is to ensure a constant temperature and in an efficient way without wasting make up water. The tank is equipped with airing nozzle, pipe to be routed to safe area (outside boiler room).
