The present invention relates to ceramic combustion chambers for use in liquid fuel burning installations and, more particularly, to ceramic combustion chambers comprising a number of prefabricated wall sections.
One object of the invention is to provide a combustion chamber of this type having simple means for joining the sections together without the use of cement or a similar binder.
A further object of the invention is to provide a joint between adjacent prefabricated sections of a ceramic combustion chamber which will hold the walls firmly in'position while the cement floor is poured after the sections have been assembled.
A still further object of the invention is to provide means for securing adjacent prefabricated wall sections together which, after the combustion chamber has been assembled, are completely embedded in ceramic material and thereby protected against the destructive action of the combustion gases.
Another object of the invention is to provide 'a combustion chamber having generally U- shaped front and rear sections which can be joined together directly or which, if desired, can be used for the erection of a combustion chamber of greater horizontal depth by the interposition between the front and rear sections on each side of the chamber of one or more extension sections, each adapted to be connected with a rear edge of the front section and with a front edge of the rear section.
Still another object of the invention is to provide a prefabricated ceramic combustion chamher in which the rear section has a height exceeding that of the front section and means are provided which permit of said sections of diiferent heights being secured firmly together without the use of cement or the like, even in installations in which the side walls of the combustion chamber have to be arranged in direct contact with the inner walls of the furnace.
These and other objects which will appear more clearly as the specification proceeds, are accomplished according to the invention by the arrangement and combination of elements set forth in the following detailed description, defined in the appended claims and illustrativelv exemplified in the accompanying drawing in which Fig. l is a perspective view of a combustion chamber according to the invention, composed of a U-shaped front section and a U-shaped rear section each consisting of two half sections and two extension sections inserted between said front and rear sections.
Fig. 2 is a separate perspective view of an extension section and Fig. 3 is a perspective exploded view of a combustion chamber similar to that shown in Fig. but without extension sections.
Referring to the drawing, ll denotes the generally U-shaped front section of the combustion chamber which consists of two half sections Ha and Mb. The two half sections are provided at their adjoining edges with semi-circular cutouts forming, after assemblage, the central firing aperture I2. They are held together by a U- shaped clip I 3 having its legs inserted into vertical holes Ma. and Mb provided in the top edges of the sections Ha and Nb. The generally U- shaped rear'section l5 comprises two half sections l5a and i512 and has a height exceeding that of the'front section II. Each front section Ha' and llb has at its rear end a flat vertical end'face l6 and a step portion I! (see Fig. 3) of equal width projecting from said end face, said step portion having a fiat vertical end face and extending from the bottom to a horizontal plane which passes approximately through the center of the firing aperture l2. Each rear section I5a and I5!) has a flat vertical end face [8 parallel to the end face of said step portion l1 and a second step portion l9 projecting from the face I8 and extending from said horizontal plane to the top of said rear section. The step portion H! has a cross section corresponding to that of the step portion l1 and is adapted to complement the latter. The step portions I1 and 19 are provided in their corresponding horizontal faces with vertical holes 20 and 2| respectively and metal dowel pins 22 inserted into the holesil! and projecting from these holes for about half of their length are adapted to fit into the holes 2| to effect a firm connection between the front and rear sections.
The two halfs 15a and I5!) of the rear section are joined together in a similar manner along stepped edges 23-24 by means of a dowel pin 25 inserted in registering vertical holes 26-21.
It will be seen that the assembled sections which are connected by the dowel pins 22 and 25 cannot pivot relative to each other, because they abut upon each other on fiat surfaces, and, as a result, a structure is obtained which is capable of resisting the outward pressure exerted upon the walls when the cement fioor is poured into the assembled wall structure. The resistance of the assembled wall elements against shown is that wall sections of diflferent height. which cannot be secured together by" u-shapcd clips inserted in holes provided in: tha top, edges of the sections, as used for instance for securing together the half section ma ma; Hbimay: be firmly connected in a very simple manner by the means provided according to the present inventiom The U-shaped front and; rear sections. of? the ceramic combustion chamber: according? to; the invention may be joined together'directly'asmdicated in Fig; 3;. or it desired, they may beused to erect a combustion. chamber of greater: horizontal depth by inserting between the; front and rear sections on each. side: of: the; chamber; one or more: extension sections: 1 shows: an; ass sembled' combustion chamber in which one: extension section; 2-85 is: provided. om each side: of the chamber. As seen bestv in; 2,, each. extension section; 28 has a stepped vertical front edge. 28 similarto; the front edge of the rear section lbw 012' I51; and. a stepped; vertical rear edge 30: similar to; the stepped vertical rear edge of the: front section. Ila: or Hb'. Verticat holes 3:! and: 32 provided in the. horizontal faces of the stepped. edges; 29 andv 3d receive dowel 33 which connect: the extension. section 28. firmly with the: front sections l. ta: and lztb and the rear sections I50: and (5b; The. top edge 3.4i of. the extension sections; may be. sloped from the height of the. rear: section. I'55 to. that of the; front section"v l L.
I claim:
1. A. ceramic combustion chamber having a prefabricated substantially U-shaped front section provided with a. central firing aperture, said front section having flat vertical end. faces and,
projecting from each: end. face, a step. portion of equal width each having? a flat vertical end face extending from the bottom to a horizontal plane considerably below the top edge of said section, a substantially U-shaped rear section having fiat end faces adapted to abut against the fiat end faces of said step portions and, projecting from each end face of said rear section, a step portion complementary to the adjacent step, portion. on said front section,, and metal dowel pins; insertable: into registering; vertical holes provided in the step portions of said front and rear sections, respectively.
