A method of cooling a heating apparatus includes a heating chamber. The method includes accumulating condensate in the heating chamber, monitoring a pressure in the heating chamber, and controlling the pressure in the heating chamber by venting the heating chamber to thereby controllably permit vaporisation of the condensate that cools the heating chamber. The pressure is controlled to maintain a rate of cooling of the heating chamber within a predetermined range. A heating installation is configured to perform the method. A cooling unit may be connected to a heating apparatus to cool the heating apparatus using the method. A method may be used for retrofitting the cooling unit to a heating apparatus to form the heating installation.

Method for cooling a heating apparatus

A vent head for a steam system is provided. In one embodiment, the vent head may comprise 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 and above the steam outlet. The baffle may have an impingement region and a convex portion which is disposed between the impingement region and the edge of the baffle. In use, the steam outlet discharges steam into the vent head chamber which impinges on the impingement region of the baffle, thereby separating entrained liquid water from the steam.

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.
