3 Claims.
This invention relates to heat exchangers in which the heat is extracted from hot gases under pressure, and it has special reference to such exchangers wherein the extracted heat is emg c 2 by providing a gas passage from conduit into space 1 that radially separates the conduit from the outer shell or casing I. A gas outlet 8 is provided in that outer shell I adjacent the top ployed for purposes such a the generation of 5 head 2 and beneath the inlet 4. Hot gases under steam. pressure enter the inlet 4, pass downwardly An important object of the invention is the through inner conduit 5, then flow around the provision of a heat exchanger which is resistbottom end 6 of the conduit into space I -beant to substantial internal pressure by the gases tween the outer shell I- andconduit 5 and thence from which the heat is tobe extracted and in 10 upwardly-through the space 1 and out of the which the gas pressure resisting shell ismainexchanger casing through side outlet 8. tained at substantially the lowest temperature Heat absorbing surface such as groups or of the .gases leaving the heat absorbing surfaces. bundles of tubes 9, I0, H and I2 are placed Another object is to facilitate the manufacture within the conduit 5 to absorb vheat from the and assembly of such heat exchangers, gases flowing thereover and conduct it to fluid Further objects will appear from the following that is passed through thetubes. In the illusdescription of an illustrative embodiment of the trative disclosure there are four such bundles invention when taken in conjunction with the of tubes 9IUII-I2, although a different accompanying drawings wherein: number may be used. Each tube group or bundle Figure 1 is a vertical cross section of the imis here shown as comprising a multiplicity of proved heat exchanger taken on line I-l of parallel rows of tubes I3 bent back and forth Figures 2 and 3; transversely of the surrounding conduit 5 to form Figure 2 is a horizontal cross section of the the represented coils.

In each of the tion details. bundles here designated 9--IflI II2 tube I The improved heat exchanger here illustrated sheets shown at 2! in Figs. 1 and 2 are placed comprises an upright shell I having top and at the bent portions 22 of the fluid-circulating bottom heads 2 and 3 capable of resisting the tubes I3 and are provided with holes for receiving internal pressure under which the heating gases those bent portions 22 thereby. maintaining flowing therethrough are delivered.

An in1et.4 duit section (I9, I8, I I or IE5). Each sheet 2| for the heating gases is provided in the top head is then bent to contact the exchangers inner Z and a gas conduit 5, which forms a seal with casing or conduit 5 and form a seal with the the top head around the juncture of inlet 4, wall of that casing. In this manner these tube with the head extends downwardly through the sheets 2| also serve as bafiles to keep the gases shell I. from short circuiting past the tube ends 22 where In this disclosure the inner gas conduit 5 is .50 the resistance to flow is relatively low. rectangular in cross section and its cross sec- Each of the tube bundle and easing section tional area is less than that of the surrounding assemblages 9-I9, I0-I8, I III and I2-l6 outer casing or shell I (see Fig. 2).

.and II I5. Thus, in the case of assemblage II-II the tube bundle I I, tube sheets 2| and the surrounding section II of the exchangers inner casing 5 all derive their support from outer casing I through the inlet and outlet headers I4 and I5 for that assemblage.
As is best indicated by Fig. 2, each and every header I4 and I5 in the heat exchanger is closed at one end 23 within the shell I and extends through the opposite shell side at 24 ad acent the headers other end. Theclosed end 23-of each header is supported from the shell I as by a bracket 25 and each header is further supported by the shell where it passestherethrough at 24. At each point 24, moreover, there is provided means for hermetically sealing the joint between the header and the shell.
Each of the various conduit sections I9, I8, I1 and I6 together with its associated tube bundles 9, IG, II and I2 and set of headers I l-I5 thus forms a unit which may be completely assembled, welded and stress relieved in the fabricating shop. When, moreover, the heat exchanger is completely assembled the entire weight of each I9I8, III'I and I2IB will be carried by the outer shell through headers I lI5 in the unique man- 'ner just explained.
In the embodiment of Figs. 3 and 4, where the heat exchanger is to be used as a steam generator, the uppermost tube bundle 9 serves as a steaming unit, the next lower tube bundle It serves as a superheater unit, the next lower tube ibundle II serves as a steaming unit and the lowermost tube bundle I2 serves as an economizerunit. When so used as'a steam generator, a steam and water separating drum 25 is provided into which both of the steaming units 9 discharge. Preferably these steaming units. (first and third counting from the exchanger top) will be provided with forced circulation pumps 21, as representedin Figs. 3 and 4.
In the complete system of Figs. 3 and 4, downcomer tubes 28 connect the bottom of the steam. and water separating drum 26 with the suction side of pumps 21; other tubes 29 and 3G connect the inlet headers I4 for the exchangers steaming ,units I I and 9 respectively, with the discharge side of the pumps; riser tubes 3! and 32 respectively connect the outlet headers I5 of the exchanger steaming units II and 9 with the steam and water separating drum 26; and a saturated steam tube-.33 connects the steam and water drum withthe in et header Id of the superheater unit Ill. The outlet header I5 of this superheater unit I is connected by ip n to the point of use. The economizer unit .I Zreceives water from the boiler feed pump (not shown) via pipe 34 connected to its inlet header I4. The economizer. outlet header I is connectedby pipe 35 to the steam and water separating drum 26.
In operation, the hot gases from which the heat is to be extracted enter the heatexchan er through inlet 4 and thence pass downwardly successively through tube bun les 9. I. I! and [2 while givin up heat. Upon leaving the economizer unit tube bundle I2 the gases are cooled.
to their final ow temperature an the cool gases thencepass upwardly throu h the space I between the out r shell or casing I and the inner Iconduit or casing 5 to leave the h at exchan r 1 throueh outlet 8. In this ma ner the outer shell I'isexposed only to gases at theirfinal low temperature and the shell temperature approaches that of the cooled gases.
This is an advantage in that the strength of the metal in the shell I, due to increase in temperature, is impaired as little as possible. Moreover, any minor leakage through the walls or joints of inner conduit 5 into the surrounding space I between outer shell I and conduit 5 will have but a negligible influence upon the temperature of the relatively large mass of cool gases passing upwardly through said space when mixing therewith.
The economizer tube bundle I2 and the steaming tube bundles II and 9 are arranged with their inlet headers at the bottom and their discharge headers at the top. For the steaming units this may be'of importance in case of failure of the circulating pum s, because water will then flow by natural circulation, from the steam and water drum through the pump, which will be of the centrifugal type, thence through the steaming un ts and back to the drum. This circulation will be sufficient to protect the tubes of the steaming unit against ov rheating.
While the preferred embodiment of the invention has been shown and described, it will be un erstood that changes in construction, combination an arrangement of parts may be made without departing from the spirit and scope of the i vention as claimed.
