The HeatCo Blow Down Vessel is designed to take water from the boiler during blowdown and reduce it to atmospheric pressure for disposal. The HeatCo Vessel 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 HeatCo Vessel is built as per requirements Section VIII of the ASME standard. The HeatCo Blowdown Vessel provides an economical means of safe boiler blowdown.
The Vessel includes a structural steel support stand for mounting to foundation. Options available are after cooler, manual cooling valve assembly, automatic cooling valve assembly, and exhaust heads.
HeatCo Blow Down Vessel are built to Section VIII, Division 1 of the ASME standard for 250 PSI design pressure. (200 PSI design pressure with 150# ANSI flanges) Blow Down Vessel design pressure should be a minimum of 25% of the boiler maximum allowable working pressure (MAWP) as recommended by the National Board.
