Abstract
1455541 Vapour generators WESTING- HOUSE ELECTRIC CORP 2 Jan 1975 [15 Jan 1974] 35/75 Heading F4A A shell and tube vapour generator having a preheater 35 is provided with a flow distribution plate 45 between the preheater bottom closure plate 41 and the tube sheet 13, the space 47 between the distribution plate and tube sheet is in communication with an annular space 33 between the shell 7 and a wrapper 31 through which the non-vapourized fluid returns to the lower end of the shell, and the flow distribution plate has circulation openings (49), Fig. 3 (not shown), permitting upward passage of the returning fluid and preventing cold fluid from the preheater from contacting the tube sheet to cause thermal stresses. The tubes 3 pass through tight-fitting holes (51), Fig. 4 (not shown), in the bottom closure plate 41 and through larger holes (49) in the distribution plate 45. In an alternative embodiment, Fig. 6 (not shown), the wrapper has openings (65) formed therein to supply preheated secondary fluid to the annular space between the wrapper and the shell.
