Abstract
A vent head for a steam system is provided. In one embodiment, the head comprises a body defining a vent head chamber and having a vent head outlet. The vent head comprises a steam inlet conduit having a steam outlet that opens into the vent head chamber and a baffle disposed within the vent head chamber above the steam outlet. A drainage passageway is provided for fluid communication between the vent head chamber and the steam inlet conduit. In use, the steam outlet may discharge steam into the vent head chamber which impinges on the baffle, thereby separating entrained liquid water from the steam. The separated water is collected in the vent head chamber returned to the steam inlet conduit via the drainage passageway.
