In the drawings, wherein for the purpose of illustration are shown preferred and modified details of the'invention, the letter A may generally designate any approved type of reverberatory furnace, provided with an altered construction B to detachably receive the replaceable liner sections C, which are preferably detachably held in place in the cpmbustion chamber of the reverberatory furnace A by means D. I
The reverberatory furnace A for the most part is conventional, and it includes a preferably slag foundation 15, upon which the conventional silica or magnesite brick floor 16 is placed with the usual upwardly facing concavesurface 17. The upstanding outer walls 18 and 19 are provided of the conventional furnace construction, having the usual inside walls 20 and 21 which 'are of silica or magnesite brick, of a special fire and heat resisting nature, since the wall portions 18 and 19 are formed of standard brick. The arch top wall construction 25 is of the usual concavo-convex formation, with the. downwardl; facing concave surface 26, which faces the floor 16 and provides therebetween the combustion chamber or compartment 27 wherein the work to be heated is placed. Theifurnace construction A furthermore includes end walls, such as the end wall 28 terials the same may be reinforced or unreinforced as desired. Special means may be provided for holding the same in place in the furnace against the side walls, or the same may be frictionally held in place in a resting relation against the side walls.
For the preferred construction the replaceable liner section C as illustrated in Figures 2 and 3 of the drawings, comprises a substantially rectangular shaped cementi-- tious body 30, of any approved thickness, which is provided with vertical reinforcing rods 31 and 32 adjacent the side edges 33 and 34 thereof, which at their upper ends are inturned in aligning relation at 36, and at their free ends in spaced relation are upturned at 38, and extend above the top edge 39 of the body 30, and at their upper ends are preferably provided with transversely aligning eyes 40 adapted to receive a grappling hook or other handling means. With- 1n the body of cementitious material is preferably cast a plurality of spaced horizontally disposed and parallel reinforcing rods 41, which at their ends are provided with eyes or other anchoring means secured to the vertical portions 31 and 32 above described, and as illustrated in Figures 2 and 3. of the drawings.
The roof or top construction 25 of the furnace is construdtedi in special manner -to receive the detachable liner sections 0, according to the form of invention herein described, but it is to be understood that the .formation of the furnace may be other than that illustrated according to the .difi'erent types'of replaceable liners provided for the stationary type of reverbe'ratory furnace, In the roof or top wall construction 25 along each longitudinal side wall of the furnace, the roof is provided with a series of spacedv openings 50, spaced on predetermined centransversely of the furnace longitudinal ters, these openings being of rectangular formation with the lengththereof extending axis, asillustrated in Figure 1 of the drawings. As a preferred construction, the open mgs 5,0 are provided along each of the side,
walls, spaced on five foot centers longitudinally of the furnace, the openings being preferably one foot by 5 3", with the length thereof arranged exactly at right anglesto the longitudinal axis of the furnace,
These openings 50 may be provided directly in the roof construction or they may be formed with any approved framework with or without a water jacket, for which suitable removable covers are provided. As the preferred construction. each opening 50 is preferably provided with a water cooled frame construction 51, which includes a rectangularshaped body comprising the end walls 53 and 54, and the longitudinal side walls 55 and56; these walls 53 to 56 inclusive having outwardly extending right angled supporting flanges 57 at the top margins thereof, which are adapted to rest upon the outer or exterior surface of the roof and top surface of the side wall portions 20 and 21 above described, with the rectangular shaped body walls of the frame 51 extending into the openings 50 in snug fitting relation therewith; it of course being understood that the frames 51 each provide passageways 6O t-herethrough communicating with the combustion chamber 27, and through which the removable liner sections 0 may pass on their way into or out of the furnace construction. The frames 51 are to be constructed of any suitable metal or ma- *terial.
.of a plurality of'substantially horizontally disposed coils 65, spiralled Within the side and endwalls 53 to 56 inclusive, and at the free ends said piping including an entrance p0rtion66 and an exit pipe portion 67 which extend laterally from the flanges 57, and therebelow, in a non-interfering relation with the placement of the removable cover constructions 70; it being understood that these laterally extending pipe portions 66 and 6'7 may have any approved coupling for connection to a suitable water supply and disposal source and location. This water cooling arrangement'is primarily provided for protection of the frame construction 51, although the same may be otherwise useful in'the eflicient placin and removal of the ,liner sections during urnace operation.
The preferred removable cover construe tion 70 for each of the openings 50 or frames and 72, and end supporting angles 73 and 74,- which are of angle metal and welded or otherwise secured at their ends, to provide upstanding side and end wall flanges and bottom horizontal flanges on each, the latter of which are adapted to support a body'75 of special brick material therein; it being adapted vto transversely reinforce the side angles 71 and 72 b body 75 ma exten above the to of the side and enc angles, but it is 'pre erred to bolts 76. The brick '1 flanges of the side and end angle walls as is well illustrated in Figures 6 and 7 of the drawings. The horizontal flanges of the side and end angles 71 to 74 inclusive rest upon the top flanges 57 of the opening frame work 51, to close the passageway or opening 60 therethrough, to consequently shut off the roof openings to the combustion chamber. For convenience in handling, the cover 70 may be provided with eye bolts 80 extending thru the body 7 5 and reinforced or otherwise supported in any approved relation on said cover plates. v
The liner sections C may be placed in any approved relation along the furnace side walls, and the preferred construction is that illustrated in Figure 1 of the drawings, wherein the liner sections are placed in practically continuous relation along the wall portions and 21 of the side wall constructions of the furnace, facing the combustion chamber 27, the lower edges of said liner sections 0 resting-upon the top surface of A the floor or bottom wall 16 adjacent the side walls.
Another arrangement is that illustrated in Figure 4, where for economical reasons the liners C are spaced slightly apart longiturtithis case the liner may be slag or of some nally of the sidewalls of the furnace.
similar material that will gradually dissolve or det'eriorate'in the molten bath. The melt-- ing or deterioration thereof will naturally take heat from the surrounding zone, and this in effect will protect the conventional furnace wall between the spaces at the side edges of .the replaceable liners.
spacing the detachable liner sections longitudinally of the walls, an economical removable liner arrangement has been. provided,,
which dissipates the heat from the conventional furnace walls in the bare spaces between the removable liner sections.
The replaceable liner section C may be.
removed or placed by means of an ordinary light travel crane or beam trolley. Suc crane of course travels the length of the furnace and to place the liner C the same is carried by the crane to the place in the furnace vwhere it is desired to be placed. The cover is removed from such location, and the liner C is lowered into the furnace through the frame passagewayfidwhich also extends thru the roof 25, as above described, and in this lowered arrangement the plane of the liner section is of course at right angles to the plane of the sidewall of the furnace a ainst which it is placed, but after the same as been lowered into the furnace combustion chamber 27, the sameis swung Thus, by
until the plane thereof isparallel with the wall, and the same is then moved up against the wall surface of the combustion chamber,
and lowered till its lower edge rests upon the bottom 16 adjacent the side wall. The liner is then secured to the side wall in any approved manner and the crane unhooked and the cover replaced. By arrangin the axis of the openings in the roof pre erably at right angles to the longitudinal axis of the furnace, the roof construction 25 is not weakened, and the full or continuous liner may be provided at each of the inside surfaces of the side walls of the reverberatory furnace.
Different means may be provided for holding the liner sections in place'against the inner surfaces of the side walls of the reverberatory furnace, either by a positive securing or merely by wedging 'or friction en-' gagement with the furnace walls. In the preferred instance some positive means is provided for holding the replaceable liner sections, which as is illustrated in Figure 8 of the drawings, consists in providing trans.
verse openings thru the side wall constructions of the furnace, from the exterior of the furnace side walls to the combustion chamber 27. After the liners have been lowered into place b the crane as above described, a special etachable bolt means secures the upper projecting ends 38 to the side Walls and this special bolt means con sists in providing a substantially T-shaped bolt or liner securing member 81, which includes a' cross head 82.engageable across the inside edges of the upstanding shanks or portions 38 of the liner, and the same furthermore includes a stem 83 extending through the opening 80 to the exterior of the same where it detachably receives a vnut- 84 which engages against a detachable plate 85 which covers the opening 80 at the outer side of the wall, and is in positive engagement with the exterior surface of the furnace walls about the margins of the opening 80. The opening 80, after securing-of the liner in place, may be filled with clay or other material, or it may be left blank if found suitable.
In lieu of the positive securing means D for each replaceable liner, the liner may have the bottom edge thereof shaped as illustrated at in Figure 11 of the drawings, to-rest' on the side marginal edge of the bottom 15 of the furnace, and the upper edge 91 of replaceable liner may wedge against the lower surface of the roof 25 adjacent the side wallconstruction; the liner body 92 of course being sufiiciently high to extend from the bottom to the roof in a wedge enga ement with the facing surfaces thereof to frictiona-lly hold the same in place. Various shapes of the bottom edges of the for small 'vention relates.
' liners may be provided, but in any event the bottom edge of the liner body may be sloped to suit the. bottom surface upon which the same may rest. The two most' important means of securing the liner in detachable position within the furnace combustion chamber is by wedging and by bolting.
-From the foregoing description of this invention it is apparent that a reverberatory furnace has been provided, the maintenance of which is more economical than the ordinary reverberatory furnace, in that the replaceable liners are provided for the furnace, which are of a practical nature, considering the fact that reverberatory furnaces are of extreme length, an average length being 125, as will be Well understood by anyone skilled in the art to which this in- I of course understand that different types of liners have been provided firing apparatus, but am not aware that a replaceable liner for reverberatory furnaces has ever been'provided which will meet the requirements incident to heating in a reverberatory type, of furnace.
