The invention is% the result of investigations and experiments that have stretched over years and have resulted in a certain upper limit for the size of the gas combustion networks that imitate infrared radiation ο This limit makes it impossible, for example to give radiant burner the same size as the bottom of a roasting oven or a grill "van conventional size _s because the networks of the burner ah, where combustion takes place, under the influence of high temperatures to which they are exposed, throw ,: if they are the required size is given "In contrast, when the surface of the burner is substantially lower than that of the oven or grill is generated a hot spot below the burner, resulting in uneven cooking" It has further been found that no faults occur, when the incitement long and narrow. " A burner of this type used with success had, for example, a width of about 8 cm and a length of about 1 _- 8 m. In other words, it was found that a net with the dimensions

For practical purposes and for the invention, however, it can be assumed that under normal conditions a burner network

In the broadest sense, the invention consists in an X-infrared radiation burner from small, distortion-free units and these units over the desired area to distribute according to a desired pattern, so that the heat uniform or non-uniform over the entire area bare only parts of a given area are distributed. Example catfish the burner is designed for use over a round pan Mg. 5 preferred, whereas for use over a square I-see or rectangular bottom of a roasting oven or grill, the burner according to Fig. 2a or Fig. TO is preferred. That the same applies to the arrangements shown in the other figures of the drawing and to further, not shown, but easily conceivable arrangements.

The structure and the mode of operation of the burner as a whole, whether it is used for tree heating purposes, as a grill in an oven or for other purposes, does not form part of the invention and is neither shown nor described It should be noted that the underside of the chamber 14 is closed by a wall 18 which carries a number of hanging burner units 20, each of which is approximately 4 ca (1.5 ^H ) in diameter. As can be seen from Pig ο 2a, the units 20 are round and are distributed over the entire surface of the base 18, but it goes without saying that the pretzel units have other shapes and can be distributed according to the patterns as shown in the other figures, and also , still be arranged in shapes and coughs other than those shown ^

A clamping plate 30, which is preferably provided with a ring 32 to delimit an opening 33, , is placed on the network 28 and, how at the point 34? welded to the bottom 18 to complete the arrangement

Instead of each burner unit individually in individual openings of the bottom 18 to assemble and fasten can be two or made more such vets sets and with a plate be welded, as shown in FIGS. 6 and 8 -..- This Plates can then easily be inserted into correspondingly shaped openings 23 in the base 18 and welded onto them there this way it avoids the work of any burner unit 20 to be welded individually
