Abstract (en)
[origin: EP0314820A1] A device for under-wagon cooling of furnace wagons (8) in tunnel furnaces (2) comprises a number of closed cooling air ducts (28, 30, 32) which fill the under-wagon channel as far as possible and are only at a small distance from the furnace wagon undersides. The cooling air ducts, which are flowed through by cooling air, ensure sufficient cooling of the furnace wagons, an exchange of cooling air from the under-wagon channel and of heating air from the combustion channel (26) being simply avoided at the same time so that no additional sealing measures have to be taken. <IMAGE>
