PATENT oFFics DANIEL n. sULLivAN, or EvANsToN, rLLINors, AssIGNoR-To THE PURE oIL con; 1 PANY, or cHrcAGo, ILLINOIS, A CORPORATION or oHIo "REPLACEABLE WALL STRUCTURE FOR FURNACES Y Application' filed February 16,-1928. Serial No. 254,834. v
rllhis invention relates .to improvements in the construction of furnace walls, and has particular application tothe walls of furnaces or heaters of thertype employed vby petroleum refiners in various oil distillations and cracking processes, although the invention is not limited in its broader aspects to furnaces for this particular industry but may be employed in any capacity where highly heated walls or surfaces, such as furnace settings, are utilized. Y Y
In ordinary furnace constructions, particularly oil heaters or stills, the Walls consist of .a fire brick wall' on the inside of the setting which is exposed to the heat of the -hot gases land ,the flames generated within the furnace In addition to this thereA is usuyally provided an outer brick wall'of similar construction but of a lower grade of brick on theoutside of the setting, there being an air space usually left between the fire brick wall and the outer brick wall. rTheV purpose of the outer brick wall has been to present a weather proof surface and at the same time to provide in a measure some insulation against heat losses for the furnace. With this ordinary type of furnace construction, however, Whenever the fire brick on the inside of the furnace has to be repaired in vcertain places, it has been necessary for brick-layers to tear into and remove the brick work from the outside with the result that these repair tasks require considerable time to execute and are expensive. To reduce the cost somewhat it has also been proposed to eliminate the use of the outer brick wall and to employ in lieu thereof walls or layers of insulation or weather proof material in the nature ,ofasbestos or mineral wool, which isapplied directly to the outer surfaces' of the fire brick wall. This latter 'method Ieliminates the use of the outer brick wall and reduces furnace cost by eliminating the labornecessary to erect it, but vhas not simplified the probleu'i of making repair-sito the lire brick wall for the reason that when the outer layers yorstrips of insulation andweatherproof .material are torn from the wall, in order to reach the inner brick, the insulation which has been removed isnot salvageable orreusable, but must be entirely replaced `over'acomparatively large area, thereby still making repair costs to furnace settings comparatively high.
. e To overcome these conditions it is an outr mutilating or destroying the same, so thatl after the Vnecessary repairs have been made to the lire brick wall, the said panels or. blocks may be restored to their proper operating po- LLI sitions and will afford the isame degree `of protection to the furnace setting as when they were first applied.
It is another obj-ect of the present invention toprovide means lfor securely holding the` blocks, sheets or panels of weatherproof and insulation material in their applied positions upon the 4outer wall of the. furnace, and
yet to permit oftheir convenient removal and replacement in a quicki'and rapidmanner without,permitting tearing, breaking or destruction thereof during the `operation and in a simple labor saving way. i
will appear as the description proceeds, the inventmn consists in the novel features of construction, combinations of elements and arrangements of parts hereinafterto be more fully `described andpointed out theappended claims. c
In the `accompanying drawing: Figure l is a perspective view showing the wallstructure of a furnace setting formed in accordance with the present invention, the various parts of thewall structure being separated .in orderto develop Vmore fully their individual construction,
Figure 2 is a horizontal sectional view taken through the wall'structure when in its loperative or completed. form.
Figure 3 is anenlarged sectional view showing in detail the Wall covering fastening element, disclosed'in Figure 2.
Vith these and other objects in view, as
Pil
Referring more particularly to the drawing, the numeral l designates the setting or wall structure comprising the present invention which may be used in connection with furnaces, kilns or other heat containing units. In the present instance, however, the wall structure comprises a vertical wall of high grade fire brick, which is indicated by the numeral 2 and which is bounded on its outer side by a course of lower grade fire brick 3. The wall structure may be braced at its ends by means of a structural metal 1 beam forming the buckstay, as indicated at 4. The buckstay has its base ange positioned upon a vertically extending end plate 5 which engages substantially the full width or thickness of the wall structure l, as shown in Figure 2. Cooperative wi-th the plate is a vertically eX- tending angle member 6 which serves to produce a reinforced corner structure for the protection of the corners of the wall.
Applied to the outer surfaces of the brick course 3 are panels or boards 7 formed from a heat insulating` material, such for example as a composition material containing mineral wool or asbestos, cork or cementitious material. These panels are held in place by means of a plurality of plates 8, or relatively thin sheets formed from a weatherproof material, which are applied to the outer surfaces of the panels 7 and completely cover and portect the panels 7 which are formed from a more perishable material. The joints formed between the adjacent sections of the panels 7 and the sheets 8 are covered by means of metallic strips 9, which are provided with openings for the reception of threaded studs 10 which are carried by and project outwardly from inner metallic strips ll, the latter being held in place in this instance by means of the angle member 6. To hold the strips 9 in position use is made of a plurality of channel clips l2, which are also formed with openings for the reception of the studs l0, the extreme outer ends of said studs heilig provided with removable nuts 13 which, when tightened` serve to draw the strips 9 and the channel clips l2 into holding engagement with the removable panels to securely retain them in their operative positions of application. In Figure 3 the strip l1 is positioned adjacent to the rear surfaces of the panels 7 and the ends of the strip 1l are securely connected to the wall structure independently of the panels 7. The strips ll carry the studs 10, which project horizontally and outwardly to receive the outer fastening members.
In view of the above it will be seen that by loosening and removing the nuts 13, the strips 11 and the channel clips 12 may be removed from the studs 10, in order that the panel sections 7 may be completely removed from their working positions within the wall structure. This enables the brick courses 2 and 3 to be readily reached for purposes of repair or access to the interior of the furnace. This means the destruction of but a minimum amount of material, which is confined to the inner brick wall of the furnace, and enables repairs to be made at the lowest cost. The insulation is not in any way damaged or injured by this operation, since after the repairs have been made the panel may be again applied to the outer surfaces of the brick wall in a simple, convenient and labor saving manner.
What is claimed is:
l. A wall structure for furnaces and the like having an inner wall formed from a heat resisting refractory material, removable and sectional pre-formed panels of heat insulating material applied directly to the outer surface of said inner refractory wall, a plurality of weather-proof sheets applied to the outer surface of said panels, a plurality of metallic strips arranged to cover the meeting edges between said panels and sheets, and removable threaded devices connecting the said strips for drawing said strips into clamping engagement with said sheets and panels.
2. A wall structure for furnaces comprising an inner wall of fire brick, removable panels of heat insulating material applied directly to and in physical contact with the outer surfaces of said brick wall, a plurality of weather-proof sheets applied directly to the outer surfaces of said panels, a plurality of metallic strips arranged to cover the meeting edges between said panels and sheets, and removable threaded devices engaging the lsaid strips for drawing the latter into clamping engagement with said sheets and panels.
A wall structure for furnaces comprising a main wall formed from a heat resisting refractory material, removable and sectional pre-formed panels of heat insulating material applied directly to the outer surfaces of said main refractory wall and in close physical engagement therewith, a plurality of weather-proof sheets applied directly to the outer surfaces of said panels, a plurality of joining strips arranged to cover the meeting edges between said panels and sheets, and removable fastening devices engaging the said strips for drawing the latter into clamping engagement with said sheets and panels to maintain the latter in close engagement with said main refractory wall. t. A wall structure for furnaces comprising an inner main wall formed from fire brick, removable and sectional pre-formed panels of heat insulating material applied directly to and in physical contact with the outer surfaces of said main wall, and fastening members positioned in registration with the meeting edges of said panels for maintaining the latter in direct physical contact with said main Wall, said fastening means' permitting of the removal of `any one of said panels, independently of the remaining panels, to afford direct access from the exterior of the Wall structure to any desired localized area of the main inner brick Wall.
In testimony whereof I affix my signature.
