P.14 ABSTRACT Separator Drain Boxes It is common for engines of the gas turbine variety to have filters at their air intakes. An example of a system employing such a filter takes the form of a tube or duct into which is drain the air to be filtered, which tube contains a number of filtering components including pads of knitted mesh and a series of zig-zag vanes. These vanes remove any entrained water droplets, and the "condensed" water runs down the vanes (under gravity) into what is known as a "drain box", from which it is led away and disposed of. The present invention proposes a novel design of drain box; instead of having the vanes bottom on a ledge in the drain box, above the drain box floor, leaving a gap between the bottom of the vanes and the floor of the drain box, and so allowing re-entrainment of the moisture, the present invention proposes that the vanes be extended to the floor of the drain box in intimate contact with the drain enclosure bottom surface. In addition to preventing re-entrainment, extending the vanes in this way provides additional structural vane support, and results in a stronger, more rigid filter system. 13/14
