  • Patent number: 6279593
    Abstract: A proactive electronic steam trap device, system, and method of removing condensate from a steam plant is disclosed. The device ensures a controlled drainage of condensate to maintain condensate level within a control band. The basic invention comprises and utilizes a steam trap chamber, a condensate level sensing system, a condensate level control system, and a condensate discharge system. Alternate embodiments include an air purge system, a flashing utility which permits reuse of high temperature steam, and an electronic temperature/pressure sensing device that will constantly monitor temperature and pressure variables in the individual condensate lines to verify the integrity of the individual condensate lines that are going into a single manifold of a steam trap.
