Abstract
Abstract A combined moisture separator and reheater suitable for a nuclear steam turbine-generator powerplant has modular reheater stages in which the tubes extend in a transverse direction to the shell centerline and a pair of moisture separator elements which are positioned in parallel along either side of the shell. The steam to be reheated enters the shell through a plurality of openings towards the bottom of the shell and flows generally in a vertical direction up through the moisture separator elements and over the rows of reheater tubes and then out of the shell through a plurality of openings toward the top thereof. A uniform flow is maintained by the appropriate arrangement of the reheater stages and the moisture separator elements. By standardizing the cross section of the combined moisture separator and reheater, the overall capacity may be readily increased by simply adding any desired number of additional axial sections of moisture separator elements and reheater stages.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
138 words
A combined moisture separator and reheater of the type having a substantially cylindrical pressure-tight shell comprising: a plurality of substantially horizontal heat exchange tubes disposed within the shell and toward the top thereof and extending in a direction generally transverse to the shell centerline, at least one longitudinally extending header disposed within the shell and communicating with the tubes, a means supplying a heating fluid to the header and tubes, a moisture separator disposed within the shell toward the bottom thereof and having elements arranged to define, together with portions of the shell, a longitudinally extending manifold supplying the elements, and said pressure-tight shell defining opposed inlet and outlet openings, said inlet opening connected to supply the manifold with steam and said outlet opening connected to remove the steam after it has passed over the heat exchange tubes.
Claim 2
Dependent Claim
138 words
A combined moisture separator and reheater of the type having a substantially cylindrical pressure-tight shell comprising: a plurality of substantially horizontal heat exchange tubes disposed within the shell and toward the top thereof and extending in a direction generally transverse to the shell centerline, at least one longitudinally extending header disposed within the shell and communicating with the tubes, a means supplying a heating fluid to the header and tubes, a moisture separator disposed within the shell toward the bottom thereof and having elements arranged to define, together with portions of the shell, a longitudinally extending manifold supplying the elements, and said pressure-tight shell defining opposed inlet and outlet openings, said inlet opening connected to supply the manifold with steam and said outlet opening connected to remove the steam after it has passed over the heat exchange tubes.
Claim 3
Dependent Claim
39 words
A moisture separator and reheater according to claim 1 further including a plurality of longitudinally extending plate members arranged to guide steam from the manifold through the moisture separator and over the heat exchange tubes to the outlet opening.
Claim 4
Dependent Claim
37 words
A moisture separator and reheater according to claim 1 further including a plurality of removable manways positioned in the shell and header opposite one another so that entry can be made to the inside of the header.
Claim 5
Dependent Claim
31 words
A moisture separator and reheater according to claim 1, further including drain means communicating with the moisture separator and adapted to remove excess liquid separated from the steam from the shell.
Claim 6
Dependent Claim
42 words
A moisture separator and reheater according to claim 1 wherein the header is a pressure-tight vessel and is partitioned Internally such that the heating fluid is directed into the tubes and returns to the header where it is removed from the shell.
Claim 7
Dependent Claim
181 words
A combined moisture separator and reheater of the type having a substantially cylindrical pressure-tight shell comprising at least two substantially cylindrical sections, each of said sections comprising: outer wall portions adapted for connecting together end-to-end, a plurality of heat exchange tubes disposed within said sections toward the tops thereof and extending in a direction generally transverse to the shell centerline, at least one longitudinally extending header section disposed within said shell sections and communicating with said tubes and having a transverse cross-section adapted for pressure-tight joining end-to-end with a header section disposed within an adjacent shell section, means supplying a heating fluid to said header and tubes, a moisture separator disposed in at least one of the shell sections toward the bottom thereof and having elements arranged to define, together with portions of the shell section, a longitudinally extending manifold supplying said elements, and said pressure-tight shell defining opposed inlet and outlet openings, said inlet openings connected to supply said manifold with steam and said outlet openings connected to remove said steam after it has passed over the heat exchange tubes.
Claim 8
Dependent Claim
181 words
A combined moisture separator and reheater of the type having a substantially cylindrical pressure-tight shell comprising at least two substantially cylindrical sections, each of said sections comprising: outer wall portions adapted for connecting together end-to-end, a plurality of heat exchange tubes disposed within said sections toward the tops thereof and extending in a direction generally transverse to the shell centerline, at least one longitudinally extending header section disposed within said shell sections and communicating with said tubes and having a transverse cross-section adapted for pressure-tight joining end-to-end with a header section disposed within an adjacent shell section, means supplying a heating fluid to said header and tubes, a moisture separator disposed in at least one of the shell sections toward the bottom thereof and having elements arranged to define, together with portions of the shell section, a longitudinally extending manifold supplying said elements, and said pressure-tight shell defining opposed inlet and outlet openings, said inlet openings connected to supply said manifold with steam and said outlet openings connected to remove said steam after it has passed over the heat exchange tubes.
Claim 9
Dependent Claim
51 words
A moisture separator and reheater according to claim 6 further including a plurality of longitudinally extending plate members adapted for joining end-to-end to those in an adjacent shell section and arranged to guide steam from the manifold through the moisture separator and over the heat exchange tubes to the outlet opening.
