Abstract
Water is flowed through bayonet tubes where it is heated to steam which is superheated in other bayonet tubes all the bayonet tubes extending from a single tube sheet. Heated water enters the inner tube of a bayonet tube assembly so that it is heated in the annulus between the inner tube and its associated outer tube and then flows into the annular space between the inner and outer tube of the second bayonet tube assembly so that it is is heated to steam to leave by the inner tube of the second bayonet tube assembly to then flow into the annular space between the inner and outer tubes of the third bayonet tube assembly to be superheated and leave the third bayonet assembly by the inner tube thereof, the flow between one or more of the bayonet tube assemblies being connected by connecting tubes which connect with thermal sleeves covering the inner tubes of the bayonet tube assemblies below the single tube sheet.
