Model BDS Blowdown Tank

A blowdown separator is the best choice when there’s not enough space to use a large tank to collect and hold the effluent while it cools to an acceptable drain temperature. The blowdown separator accepts boiler blowdown and vents the portion that flashes to steam but does not store the effluent until it cools. Instead, a temperature-controlled mixing valve mounted in the tank’s discharge piping adds cold make-up water to cool the effluent as it immediately discharges to the drain.

Options

Blowdown can be piped so that its latent heat is recovered and used to preheat boiler feedwater.

Features & Benefits

  • Standard blowdown separator design pressure is 50 psi; the tank’s vent is sized to limit the vessel pressure to 5 psi
  • Boiler blowdown enters the vessel’s lower-pressure environment, where approx. 30% flashes to steam, then flows out the tank’s vent
  • Blowdown effluent collects in the bottom of the tank, where a mixing valve in the tank’s discharge piping adds cold make-up water, cooling the effluent below 140°F as it immediately discharges to the drain

Application

Most commonly used where space limitations don’t allow for a large tank.
