Vapor generator organization utilizing liquid metal or molten salts

Claim 2

The vapor generator organization of claim 1 wherein the means for passing the vapor collected in said vapor collection means through said first annular flow passages includes separating means for separating said vapor-liquid mixture so as to allow passage of the separated vapor through said first annular flow passages while returning the separated liquid so as to be recirculated through said inner tubes.

Claim 3

The vapor generator organization of claim 1 wherein said bayonet tube arrangement means extend within each of said pressure tubes for a length less than the full length of the respective pressure tubes, each of said bayonet tube arrangement means having a flow guiding extension on the end thereof extending the remaining pressure tube length.

Claim 4

In a vapor generator organization wherein a heating medium such as liquid metal or molten salts is used to produce a superheated vapor by the indirect transfer of heat to a vaporizable liquid, the combination comprising: a. a vertically elongated vessel, said vessel having an inlet chamber, a heat exchange chamber and a collection chamber axially spaced therein; b. a first tube sheet secured to said elongated vessel located between said inlet chamber and said heat exchange chamber and a second tube sheet secured to said elongated vessel located between said heat exchange chamber and said collection chamber; and c. a tube bundle located within said heat exchange chamber, said tube bundle comprising: i. a plurality of pressure tubes connected between said first and second tube sheets and in fluid communication with said inlet and collection chambers; and ii. a plurality of bayonet tube arrangements, each having a central internal tube portion extending concentrically within an outer tube portion, closed at one end, for a length less than the full length of the outer tube portion and forming a flow annulus therebetween, one of said bayonet tube arrangements concentrically located within each of said plurality of pressure tubes extending therewithin for a distance less than the total length of the respective pressure tube and forming a flow annulus therebetween; d. means supplying vaporizable fluid to said inlet chamber; e. means within said inlet chamber to direct the flow of vaporizable liquid to each of said central internal tube portions; f. means within said inlet chamber connecting the annuli formed between said central internal tube portions and their respective outer tube portions to the annuli formed between said bayonet tube arrangements and their respective pressure tubes; g. means for circulating the heating medium through said heat exchange chamber about said plurality of pressure tubes; and h. a conduit for withdrawing vapor collected in said collection chamber to do useful work.

Claim 5

The vapor generator organization of claim 5 wherein the means connecting said two annuli includes a means for separating the vapor and vaporizable liquid received from said first-mentioned annuli and passing the vapor to said second-mentioned annuli while returning the vaporizable liquid to said inlet chamber for recirculation.

Claim 6

The vapor generator organization of claim 5 wherein each of said bayonet tube arrangements has an extension attached to the closed end thereof, said extension being of a length so as to extend from its respective bayonet tube arrangement the remainder of the length of its respective pressure tube.

Claim 7

The vapor generator organization of claim 5 wherein the means for circulating the heating medium through said heat exchange chamber about said plurality of pressure tubes includes: a. inlet nozzle means connected to said heat exchange chamber of said elongated vessel; b. outlet nozzle means connected to said heat exchange chamber of said elongated vessel below said inlet nozzle means; and c. baffle means for directing the flow of heating medium from said inlet nozzle means to said outlet nozzle means, said baffle means comprising: i. a first baffle surrounding said tube bundle and extending for a length therealong from above the level of said nozzle inlet means to below the level of said nozzle outlet means; ii. a second baffle sealingly connecting said first baffle to said elongated vessel, said second baffle located below the level of said inlet nozzle means; and iii. a third baffle located between said first baffle and said elongated vessel, said third baffle connected to said elongated vessel below the level of the nozzle outlet means and extend above the level thereof.
