- the cooling of the carriage or slide superstructure 9, in particular of the support elements 17, is necessary in order to prevent the tunnel kiln cars or carriages 1, which are still warm from the previous firing cycle, from heating up the lowermost combustibles too quickly. Because can lead to cracking of the fuel.
- the heat storage of the support elements 17 of the invention is very low due to their low mass, which ensures good heat exchange during firing. This also ensures a lower difference in the temperatures of the lower and upper fuels, ie a homogenization of the temperatures and a good quality of combustion.
- insulating material can be introduced, whereby the carriage or carriage base 3 is thermally insulated from the combustion chamber 7 very well.
- the structure is very low and it can, for example, compared to the known constructions. a layer of firing supports 35, 35a more of the tunnel kiln car or carriage 3 are added. The capacity of the tunnel kiln 1 according to the invention is thereby increased.
- the positive securing of the support frame 22 is realized differently on the supports 16, for example by the supports 16 have protruding elements which engage positively in recesses in the support frame 22.
- a support frame 22 may also be mounted only on a single support 16, respectively.
- the support element 17 according to the invention may be mounted on other components than the supports 16, e.g. on the uppermost layer in the case of a layered wagon or sled superstructure. It is only important that the juxtaposed support elements 17 demarcate the tunnel kiln car or - carriage 3 from the combustion chamber 7 and form the carriage or carriage top, are placed directly on the lowest Brenngutaki 35 a.
- a support frame 22 can accommodate a plurality of juxtaposed bottom firing tray 35a.
- cover plates 23 cover the support frame 22 from below.
- a cover from above is preferred.
