Abstract
Abstract A plurality of vapor generators are connected in common to a single water separator. Collars are used to connect the generators to the separators and the collars can be welded together in the field. The water which is separated out in the separator is returned to the vapor generators and mixed in with the cold feed water.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
107 words
A vapor generating plant comprising a vapor generating section having a plurality of pressure vessels for generating vapor therein, each pressure vessel having a plurality of tubes therein for passing a primary medium therethrough in heat exchange relation with a secondary medium passing into said pressure vessel to generate the vapor from the secondary medium; a water separating section having a separating vessel therein connected in common to said pressure vessels to receive the generated vapor therefrom; and a lining surrounding said tubes in each pressure vessel, said lining having an extension thereof extending into said separating vessel to direct the generated vapor into said separating veSsel.
Claim 2
Dependent Claim
107 words
A vapor generating plant comprising a vapor generating section having a plurality of pressure vessels for generating vapor therein, each pressure vessel having a plurality of tubes therein for passing a primary medium therethrough in heat exchange relation with a secondary medium passing into said pressure vessel to generate the vapor from the secondary medium; a water separating section having a separating vessel therein connected in common to said pressure vessels to receive the generated vapor therefrom; and a lining surrounding said tubes in each pressure vessel, said lining having an extension thereof extending into said separating vessel to direct the generated vapor into said separating veSsel.
Claim 3
Dependent Claim
34 words
A vapor generating plant as set forth in claim 1 wherein said separating vessel is connected to said pressure vessels to return separated water from the generated vapor passing therethrough to said pressure vessels.
Claim 4
Dependent Claim
68 words
A vapor generating plant as set forth in claim 2 which further comprises means connected to each pressure vessel to direct a flow of fresh feed water into each pressure vessel, and means for measuring the level of separated water in said separating vessel to control the flow of fresh feed water into each pressure vessel in dependence upon the level of separated water in said separating vessel.
Claim 5
Dependent Claim
43 words
A vapor generating plant as set forth in claim 1 wherein said separating vessel is spherical and wherein said water separating section further includes a water separating element and a superheating element therein in the path of flow of the vapor passing therethrough.
Claim 6
Dependent Claim
42 words
A vapor generating plant as set forth in claim 1 which further includes a jacket disposed in spaced relation to said lining extension to define an annular gap therebetween for directing collected liquid in said separating vessel back into each pressure vessel.
Claim 7
Dependent Claim
32 words
A vapor generating plant as set forth in claim 1 which further includes means in said lining extension for producing a twist in the flow of vapor passing into said separating vessel.
Claim 8
Dependent Claim
49 words
A vapor generating plant as set forth in claim 1 wherein each said pressure vessel has a wall spaced from said lining to define an annular space for the flow of secondary medium into said pressure vessel and an inlet for fresh secondary medium communicating with said annular space.
Claim 9
Dependent Claim
21 words
A vapor generating plant as set forth in claim 1 which further comprises thermal insulation surrounding said pressure vessels in common.
