Abstract
A flow constriction device for the complete removal of condensate from steam and compressed air lines and steam-using equipment. This device incorporates the insertion of a uniquely designed convergent/divergent nozzle into a body piece. The body piece is installed within the piping system using existing means. The nozzle is protected from blockage with a screen secured at the inlet of the body piece. The dimensions of the convergent/divergent flow channel are determined for each application taking into account factors of pressure differential and the flow rate of the condensate to be removed. The design of the assembly allows for easy interchanging of the nozzle piece to meet changes in system conditions. The body of the device can be reused, and the nozzle piece can be changed without disturbing the in-line screen element.
