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 (2) having an entrance end (5), an entrance passageway (6), an intermediate passageway (7), an exit passageway (8), and an exit end (9). The intermediate passageway includes a cylindrical venturi tube (10), which is adjacent an exit of the entrance passageway (6), and a downstream cylindrical discharge-transition passageway (11), which is adjacent an exit of the venturi tube (10). The downstream cylindrical discharge-transition passageway (11) has a diameter larger than a diameter of the venturi tube (10) and a length larger than a length of the venturi tube (10). A ratio of the length to the diameter of the downstream cylindrical discharge-transition passageway (11) 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 (11) to the length of the venturi tube (10) may be greater than five.
