CONTINUOUS FLOW STEAM CONDENSATE REMOVAL DEVICE

摘要

The application discloses a continuous flow steam condensate removal device for use in a steam condensate removal system of a type which includes a steam condensate line, a Y-strainer for removing debris from the steam condensate line, and a condensate return line. The condensate removal device is an elongated unitary one-piece body having an entrance end, an entrance passageway, an intermediate passageway, an exit passageway, and an exit end. The intermediate passageway includes a cylindrical venturi tube, which is adjacent an exit of the entrance passageway, and a downstream cylindrical discharge-transition passageway which is adjacent an exit of the venturi tube. The downstream cylindrical discharge-transition passageway has a diameter larger than a diameter of the venturi tube and a length larger than a length of the venturi tube. A ratio of the length to the diameter of the downstream cylindrical discharge-transition passageway is greater than five in order to provide an efficient flow of condensate through the device. A ratio of the length of the downstream cylindrical discharge-transition passageway to the length of the venturi tube may be greater than five.
