A commercial boiler blowdown separator is designed to take water from the boiler during blowdown and reduce it to atmospheric pressure for disposal. The Hurst Boiler commercial blowdown separator accomplishes this by separating the subsequent flashed steam from the hot water. As the blowdown enters the vessel, it is forced into a centrifugal pattern by means of a striking plate. The steam is vented to the atmosphere through a top connection. The Hurst boiler blowdown separator is built as per requirements Section VIII of the ASME Code and stamped by the National Board of Pressure Vessel Inspectors. The Hurst Boiler commercial blowdown separator provides an economical means of safe boiler blowdown.
