<p>A baker's oven with heating gas circulation has a number of baking chambers (1) above one another and, in between or above these and below these, radiators (3) which are flowed through by the heating gases and connected to distribution and collection shafts (11, 12) situated on the rear side of the baker's oven. Each radiator (3) is divided, by an intermediate wall (8) which does not quite reach as far as the front wall (6), into forward and backward running flues (9, 10) for the heating gases, which merge with one another at the front wall (6), there being provided in the places of increased heat requirement means for bringing about an intensified heat transmission. In order, with as low a pressure loss as possible in the circulating circuit and with simple construction, to provide effective measures for intensifying the heat emission in regions of increased heat requirement, the forward and backward running flues (9, 10) are formed by a horizontal intermediate wall (8) and arranged above one another. Alternatively or additionally, it is envisaged that on the one hand the height of the forward running flue (9) of the radiator (3) decreases in the direction of flow of the heating gases and that on the other hand, within boundary layers, close to the wall, of the heating gases flowing through the flues (9, 10), in the front part of the radiator (3) and at a distance from its inner wall surfaces, transverse rods (13) are arranged. <IMAGE></p> |
