9 Claims. (Cl. 261-159) This invention relates to the protection of a metal port structure against a high temperature fluid flowing therethrough. It is a metal port structure of novel fluid cooled design adapted to prevent burn out or loss of structural integrity under severe operating conditions.
Situations frequently arise wherein high temperature fluids are to pass through ports at conduction flux rates sufficient to burn out bare metal.
In reaction vessels growth must be accommodated and there is usually a desire for positive sealing. To attain these goals, supporting flanges are often arranged about a port. In the face of structural and process requirements, space devoted to the cooling of port structures is grudgingly allotted. Metal is often used for these port structures because of a need of versatility and resistance of thermal shock.
Protection of port structures can be aggravated by plant start ups and shut downs which occasion differential expansions and contractions.
Various liquid cooled metal port structures have been attempted. But these attempts were frustrated by one or a combination of the following:
Uneven contact of cooling fluid with the metal surface exposed to hot gas. This difficulty has generally been attributed to pulsations or to swirling of cooling fluid supply.
Diiferential thermal expansion or contraction of the port structure relative the parent structure, especially at plant start ups and shut downs.
Inadequate supply of cooling fluid.
The present invention overcomes these difliculties by a novel port structure. More particularly, the interior of the port is lined with a protective conduit divided along its length by a weir into an inward chamber, inward relative the port, and an outward chamber. Cooling fluid is introduced into the inward chamber. Overflow cooling fluid is delivered from the inward chamber to the outward chamber. Exhaust means accommodate the removal of cooling fluid from the outward chamber.
Basically this advance oflers improved contact of cooling fluid against the conduit even in the event of erratic cooling fluid supply.
In vertical protective conduits, if the pressure or" the cooling fluid supply accidentically drops, cooling fluid still remains in the critical inward chamber.
Another facet of this invention is the mounting of the conduit on a flexible member spaced from the parent structure and capable of deflecting to accommodate differential contraction or expansion of the conduit relative the parent structure.
A port structure defining the entrance to a quench boot is particularly suited to this invention. The presence of a cooling liquid for direetcontact heat exchange, with a gas makes a metal the obvious material choice for Also, in this application the cooling liquid can be discharged from the outward chamber of the protective conduitqto cool. the inner tube of the opportunity of adding a vapor to the gas, In a synthesis gas generator system the use of water as a cooling fluid 3,164,844 Patented Jan. 5, 1965 ICE introduces steam into a CO and H stream at the quench boot. The resulting mixture is cooled for economical piping. Also the steam is subsequently employed in the presence of a suitable catalyst for the water gas shift reaction wherein carbon monoxide reacts with the water to yield hydrogen and carbon dioxide.
The use of this invention for introduction of fluids for chemical reactions with a hot gas stream in a quench boot has not been overlooked. For example, it is sometimes desirable to react a liquid hydrocarbon with hot gases. This can be accomplished in a quench boot with the liquid hydrocarbon serving as the cooling fluid.
These and other advantages will appear more fully from the accompanying drawings wherein:
iGURE I is a fragmented vertical section of a quench boot with a port structure according to the present invention.
FIGURE II is an enlarged section of the flange and port structure of FIGURE I.
FIGURE III is a section taken along line III-III of FIGURE 1.
FGURE IV is a section taken along line IV-IV of FIGURE III. 7
' In the shown embodiment the hot fluid is a gas which exits reaction vessel 1 by way of throat 2 formed in open base 3. Throat 2 is generally fabricated of a heat resistant material such as a ceramic. Reaction vessel 1 has .its open base bolted to casing 4 of quench boot generally designated 6. Flange 7 defines port 8 arranged to receive hot gas from throat 2. The illustrated quench boot is used to cool hot synthesis gas by direct contact with water. 7
Theport structure generally designated 9 is metal. So, for protection from burn out, continuous conduit 11 lines the interior of port 8. In the shown embodiment port 8 is circular in cross section so protective conduit 11 cylindrical However, if other than circular port configurations were selected, they would be lined accordingly.
Protective conduit 11 is water cooled. Water is introduced to conduit 11 by infiow means shown as pipes 12 screwably connected to flange 7 to communicate with lateral bore 13 formed there/through. Bore 13 comlower portion of inward chamber 21. Weir 18 retains water in inward chamber 21. Knife edge 23 is spaced from top 16 to define passage means for passing overflow water from the upper portion of inward chamber 21 to outward chamber 22. Due to flow obstruction by weir 18 the water is unable to attain substantial angular velocity normal to the axis of conduit 11 so swirling is reduced. Passage 24 is not large enough to. accommodate a swirl flow, but it communicates with the lower pressure of outward chamber 22 thereby providing a means for attenuating surges in the inward chamber.
The tendency toward swirling is more severe with less viscous cooling fluids. Pulsations are more meaningful at higher specific gravities.
The protection. of vertical port structure 9 is illustrated in this embodiment, but it should be realized by sneaesa means might be varied in size about protective conduit 11 to account for elevation differences.
Under various operations conditions, especially shut down and start up, thermal gradients may exist between protective conduit 11 and its parent structure. To relieve such stresses, conduit 11 is connected to flange 7 by a flexible member shown as cylindrical outer wall 17. Outer wall 17 is arranged to deflect, thereby relieving stresses occasioned by differential contraction of conduit 11 relative flange 7. To accommodate expansion of conduit 11 relative flange 7 outer wall 17 is spaced from inner rim 26 of flange 7 to define clearance 27.
For a closed system the exhaust means would most likely be a pipe similar to pipes 12 but communicating with outward chamber 22. However, it is preferred that exhaust means be an exhaust outflow 28 defined by con duit 11 to communicate with outward chamber 22 for exhausting cooling fluid to quench boot 6. Fluid in out- Ward chamber 22 is substantially at the pressure of the quench boot. Thus the open system here shown improves the surge attenuation of passage 24.
In the shown embodiment, efliuent from outward chamber 22 joins the hot gas stream passing through inner tube 29 which is suspended from flange 7. The cooling fluid protects the upper portion of inner tube 29. Inner tube 29 is spaced from casing 4 of the quench boot to define first annulus 31. Level 32 of water, is maintained by a source of water (not shown) which communicates with the first annulus by way of opening 33. Baflie 34 is connected to casing 4 at its lower extent. The upper extent 36 of bafiie 34 projects upward into the vicinity of flange 7 to define pass 37. Battle 34- is spaced from casing 4 to define second annulus 3t; therebetween.
Gas from reaction vessel 1 exits inner tube 29 via ports 39 and serration grooves 41. The gas bubbles upwardthrough water in first annulus 31 and is further cooled thereby. Suspended water is removed from the gas by centrifugal action induced by angular acceleration. Flow through pass 37 from first annulus 31 to second annulus 38 imparts angular acceleration to the gas.
Gas is collected by second annulus 38 for exit through opening 42.
