Patented Mar. 24,' 1953 UNITED STATES PATENT OFFICE FURNACE SKEWBACK-CHANNEL COOLER William C. Bulmer, Aspinwall, Pa.
Application April 29, 1950, Serial No. 158,961
3 Claims. (Cl. 122-499) for furnaces, and more particularly to improve- The ske back-channel coolers are subjected to the higher temperatures, and thus are more likely to requirerepairs or replacement than the door the present practice involves interruption of the operation of the furnace, a process attended by great expense, which, if possible, must be avoided.
The present invention enables the skewbackchannel cooler to be removed and replaced without interruptinglthe furnace operation, the skewback channel being removably supported in a seat formed in the horizontal body of the hollow door frame, said seat being walled to prevent the passage of water from the interior of the hollow body to the seat, 'or vice versa.
"The skewback-channel cooler is a separate elongated box-like enclosure supplied with a current of water which is entirely separate from the water supply to the body of the door frame and to the depending legs of the latter, and the water is admitted and released to and from the cooler through pipes extending down through passages leading from the top of the horizontal body of the door frame but walled 'oif therefrom. Means are provided for detachably maintaining the skew'back-cooler and its water pipes in operative position in the door frame, which means are capable of quick release when the skewback-channel cooler is to be removed. When the channel cooler has been repaired or a new cooler is to be substituted, itis inserted in its seat and the retaining means is readjusted to hold the cooler in operative position.
Y In the accompanying drawings, which disclose practical embodiments of the principles of my invention:
Fig. 1 ;;;is..a.front elevation of a furnace door framewith the skewback-cooler in position;
- frame proper, and such repairs or replacement in I 2 is shown suspended from above by means of de-. pending links I4 pivotally connected to the lugs 15, one extending upwardly from the door adja= cent each side of the same, so that the door may be opened or closed by vertical movement of the door.
The supply of a current of water to the hollow body and legs is through the vertical supply pipe I6 which extends down from the top of the body Ill and one of the legs II and by a horizontal connecting pipe H in the body It above the door opening and thence by a depending pipe l8 in the opposite leg II. The outlet pipe 18 is con-'- nected to the interior of the body at the top of the latter adjacent to the opposite side of the latter. The pipes l6 and I9 are closely adjacent the opposite vertical sides of the door frame to toFig. 1 but showing a modified mounting for provide space for the skewback-dhannel cooler 20 and its water connections.
The skewback-channel cooler 2:! is a separate unit removably mounted in a horizontal walled opening or seat 2| which extends through the hollow body ll] of the door frame from the interior to the exterior of the furnace and the front wall of said cooler is provided with a closure plate 22, fixed to the cooler, which closure overlaps the horizontal edges of the opening 2| in the front of the door frame, so as to seal said opening from the outward escape of gases when the skewbackcooler is in place and the furnace is in operation.
The front portion of the body I0 is provided at either side with a vertical recess 23 walled off from the interior of the body or lintel l0 and extending inwardly from the front of the latter. The recesses 23 have their vertical fronts open to the exterior of the doorframe and communicate at their lower ends with the seat 2!. Extending downwardly from the top of the body are the two pipes 24 and 25, the pipe 24 being detachably connected at its top with a cooling water connection, and the pipe 25 by a water-outlet pipe. The lower ends of these pipes are firmly connected to the interior of the skewback-channel cooler 20, preferably by welding. Thus a flow of cooling water may be maintained through the sk'ewback-channel cooler 20 independent of the flow of water through the body section ill and the leg sections l|-|I, the interiors of the latter being in communication for the flow of water therethrough.
The skewback-channel cooler 20 is provided at its rear portion with a hollow rearwardly extending nose portion 26 which, as shown in Fig. 4, extends beneath and provides for the cooling of the skewback-channel 2?- supporting the furnace roof 28. The interior of the .skewbackchannel cooler 20 and its nose portion 26 is provided with longitudinally extending baffles 29 which are provided with ports 30 adjacent their opposite ends, so that the cooling water admitted to the cooler will be baflied back and forward within the entire interior of the cooler and its nose portion, as it is admitted through the pipe 24 and escapes through the pipe 25.
The skewback-channel cooler and the supply pipes are detachably held in place in the seat 2| by any convenient means, such, for instance, as the hook bars 3| which are provided with arcuate front ends 32 engaging about the pipes 24 and 25 at the top of the body I 0, and having their rear ends provided with hooks 33 which engage the edge of the top flanges of the skewback-channel. A wedge 34 may be driven between the hooks 33 and the channel flange to hold the pipes 24 and 25 and the cooler detachably in position.
- ,Itiis obvious-that the skewback-channel cooler 20 may thus be quickly removed for repairs or replacement without removing the door frame or the door which is raised out of the way, and the repaired cooler or a new one may be quickly put in position, without interrupting the furnace operation, or requiring the removal of the door frame, thus greatly reducing costs and time expenditure.
Referring now to Figs. 6 and 7 of the drawings, in this embodiment the furnace door and door frame are removed to dismount the skewback-channel cooler.
Thus the seat 35 in which the skewbackchannel cooler 20 is supported does not extend clear to the front of the hollow body 10 of the door frame but is open only at the rear to allow the nose to extend beneath the skewback-channel 21, and the walled off recesses 36 are formed in the rear portion of the body 19 and extend upwardly'to the top. of the cooler to receive the inlet and outlet pipes 24 and 25 of the cooler 20. The cooler and its pipes are detachably held in place by the vertical plates 31 which close the open rear walls of the recesses and are prevented from outward movement by the inwardly protruding flanges 38 formed by extending the rear wall of the body at either side of the recesses 36. These plates may be readily pulled vertically out of their recesses when the cooler is to be removed. Afterthe cooler is in place the plates are slipped down'into position, thus anchoring the cooler and its pipes in position. The space between the opposite flanges 3838 is sufiicient to permit the pipes 24 and 25 to pass between them when the cooler is removed from or inserted into operative position.
I claim:
, 1. In a fluid cooled facing and skewback-channel structure for a furnace opening, the combination comprising a hollow horizontal lintel forming the arch and vertical spaced apart hole lowleg members for facing a furnace'opening, .fluid connections to direct the flow of cooling fluid through the interior of said lintel. and through the interior of said leg members, means defining a horizontally disposed seat in said lintel spaced above the lower edge of said arch, said seat being walled off from the interior of the lintel to provide the circulation of cooling fluid all around the seat, a skewback-channel cooler having a hollow head and nose, said head being shaped to be removably inserted into said seat to position said nose beyond the rear plane of the lintel when applied to a furnace, said nose .portion extending inwardly beneath the skewbackchannel of the furnace with the head in said seat,
