Guillotine Gate for Power Plants

UGES Guillotine Gates deliver heavy-duty vertical shutoff for the large openings in U.S. power plant fuel and ash handling, including coal yard reclaim, boiler bunker feed, and bottom ash systems. Rugged blade-and-frame construction is built for continuous duty, while an enclosed, dust-tight design helps keep combustible coal dust under control. They are built to stand up to the around-the-clock demands of power generation.
