HEAT EXCHANGER Filed 001'.. 23, 1959 .,4 7n 'I V /4 r W 4 i E IlA 'IIJ "Il l] a INVENTORS /Sffe 7 ,777/0 ras z- States This invention relates to heat exchangers in general and has particular reference to a steam generator for converting water into steam by the addition of heat thereto from a higher temperature liquid. More particularly, the invention relates to a steam generator in which water is circulated through a series of tubes which extend into a body of liquid contained within a tank and from which heat is absorbed to convert the water into steam.
A steam generator of the type described herein is suitable for use as a heat exchanger for producing high temperature steam for operating ya steam turbine to generate electricity.
The heat exchanger described herein is designed to provide an interchange of heat between liquid sodium and water, which presents many problems in that provision must be made for the possibility of a break or failure of one of the tubes of the heat exchanger which would result in contacting water with the sodium. The resultant reaction between the water and sodium would, of course, generate high pressures within the heat exchanger and the possibility of the occurrence `of such pressures must be taken into consideration in the design of the heat exchanger for safety reasons as well as for other considerations. Since a heat exchanger yof this type must be very large, it would be very dimcult and expensive to design and build a container `structure sufficiently strong to Withstand the pressures that might be encountered in the event of a tube break or other failure of some part of the heat exchanger. The present invention provides a heat exchanger of the type described having provisions -for preventing the -build-up of high pressures within the heat exchanger in the event of a tube failure so that the heat exchanger need not be unduly heavy or expensive and, in fact, may be considerably lighter and less expensive than a heat exchanger of comparable capacity not provided with the pressure relief system of the present invention. p
The steam generator disclosed herein consists essentially of a container or tank structure through which liquid sodium is circulated and a series of heat exchange tube assemblies extending downwardly into the body of liquid sodium contained within the tank. The water and the steam generated therefrom are circulated through the tubes out of contact with the liquid sodium. In accordance with the present invention, an inert gas space is provided above the liquid sodium within the tank to provide a surge chamber and an outlet or discharge line leading from the inert gas space is normally closed by a frangible diaphragm which is designed to rupture or break at pressures in excess of the pressure normally maintained within the inert gas space, thereby to open the discharge line to carry off the reaction products of the water and sodium and dissipate the pressure in the tank in the event of a break or rupture of one of the heat exchange tubes.
The principal `object of the invention is to provide a heat exchange device for the exchange of heat between two liquids which, if brought into contact, would generate high pressures within the heat exchanger.
It is a further object of the invention to provide a heat exchanger of this type having provisions for preventing the build-up of high pressures within the heat exchanger.
A further object of the invention is to provide a heat tent exchanger of the type described having pressure relief means incorporated therein so that the weight and the manufacturing cost of the heat exchanger may be kept at a minimum.
Other and further objects of the invention will be apparent from the following description and claims and may be understood by reference to the accompanying drawing, which by way of illustration shows a preferred embodiment of the invention and what we now consider to be the best .mode of applying the principles thereof. Other embodiments ofthe invention may be used without departing from the scope of the present invention as set forth in the appended claims.
In the drawing:
FIG. l is a vertical sectional view through a heat exchanger embodying the present invention; and
FIG. 2 is a Vertical sectional View through one of the heat exchange tube assemblies employed in the hea-t exchanger.
The heat exchanger includes a generally cylindrical vertically disposed tank 10 having a bottom wall 12 'and 4an annular ange 14 at its upper end against which a tube sheet 16 is seated. A steam header 18 in the form of a cylindrical ring is seated upon the tube sheet 16 and an inlet header 20 forms the top of the heat exchanger and seats against the upper rim 22 of the header 18. A second tube sheet 24 is clamped between the flange 22 and the underside of the inlet header 2G. Suitable gaskets may be provided between the several parts described to provide a sealed tank structure. I
The tank 10 is provided with an inlet itting26 through which liquid sodium is supplied to the tank. The tank is provided with an outlet l28 adjacent its lower end. The liquid sodium is pumped through the tank 10 by suitable pumping means forming no part of the present invention. The sodium is maintained at a level within the tank indicated by the line 30.
A series of tube assemblies 40 extends downwardly into the liquid sodium contained in the tank 10. Each tube assembly 40 comprises an outer tube 42 secured to and extending downwardly from the tube sheet 16. The tubes 42 are closed at their lower ends and at their upper ends 44 open into the space 46 defined between the tube sheets 16 and 24. Each tube assembly further includes an inner tube 48 secured to and supported from the ltube sheet 24 and extending downwardly ytherefrom into the tube 42 in concentric relation thereto. The water tubes 48-are open at their upper ends 50 so as to be supplied with water entering the inlet header 20 through the water inlet 52. The tubes 48 terminate at their lower ends adjacent the bottom of the outer tubes y42. The water to be converted to steam ilows into the inlet 52-and downwardly through the tubes 48 and then upwardly through the annular spaces 54 defined between the tubes 48 and the tubes 42. As the water passes upwardly through the `annular spaces 54 in counterflow heat exchange relation with the liquid sodium circulating downwardly through the tank '10, the water is converted into steam which passes through the upper ends 44 of the tubes 42 into the steam header 46 from which the steam is drawn ont' through the outlet 60'.
The -space between the level of the sodium 30 and the tube sheet '16 defines -a surge chamber 62 which may be filled with an inert gas. The tank is provided with an inlet 64 through which an inert gas such as argon may be supplied .to the space A62 and maintained therein at a predetermined pressure. A discharge pipe 66 leads from the surge chamber 62 and is closed by a pressure relief diaphragm 70 which may be made of a suit-able frangible material which will break or rupture inthe event the pressure within the chamber 62 increases substantially above the normal pressure maintained therein.
A heat exchanger of this type is necessarily a very large structure and may be of the order of 30 feet or more in height and may contain several hundred individual tube assemblies. Since the two liquids involved here will react chemically if contacted with each other and generate high pressure reaction products, character would ordinarily have to be constructed of very thick and expensive materials in order to provide a safety factor in the event of a failure in one or more of the tube assemblies such as would result in contacting theY liquid sodium with the water. The inert gas chamber 62 and the pressure relief diaphragm 70 provide a means for .obviating the necessity of constructing the tank 10 from unduly heavy and expensive materials. In the event of a tube failure, the resultant high pressures 'resulting fromV the reaction between the two liquids may expand into the inert gas space 62 to maintain the pressure to which the tank d is subjected below a certain critical value. If the pressure rises s-uiciently within the chamber 62, the diaphragm 70 will rupture to open the discharge line 66 and enable the reaction products to be drawn off through the discharge line to maintain the pressure within'the tank 10 below its critical value.
A heat exchanger ot Ythe typedescribed may be required to handle several hundred thousand pounds of liquid sodium per hour'at a temperature of several hundred degrees and, similarly, the iiow rate of the water may be of the order of several hundred thousand pounds per hour at somewhat lower temperatures, while the steam will be heated to nearly the temperature of the incoming sodium at pressures of several hundred pounds per square inch. It will, therefore, be appreciated that, the problems involved in using heat exchange liquids of this type at such temperatures and pressures, would require very heavy and expensive equipment without the safety facvtors provided by the present invention.
While the* present invention has been described in connection with a heat exchanger employing liquid sodium and Water as the .two heat exchange mediums, it will be apparent that this invention will be useful in other applications and in other heat exchangers in which heat is exchanged between two dilerent liquids than those described herein.
While we have illustrated and described a preferred embodiment of our'invention, it is understood that this is capable of modification, and We therefore do not wish to be limited to the precise details set forth but desire to avail ourselves of such changes and alterations as fall within the purview of the following claims.
