Claim:
A vent head for a steam system, comprising: a body defining a vent head chamber and having a vent head outlet; a steam inlet conduit extending along a vertical axis and having a steam outlet that opens into the vent head chamber; and a baffle disposed within the vent head chamber, with respect to the vertical axis, above the steam outlet, the baffle having an impingement region and a convex portion which is curved out of the plane of the impingement region and is disposed between the impingement region and the edge of the baffle; wherein the steam outlet, upon being operatively connected to a steam system, is configured to discharge steam into the vent head chamber which impinges on the impingement region of the baffle, causing entrained liquid water to adhere to the baffle; wherein the convex portion has a radius of curvature configure to cause water vapour to flow along a flow path adjacent to the convex portion to the vent head outlet, and further to cause water droplets to be discharged from the convex portion out of the flow path to collect within the vent head chamber.
