Embodiment Construction

[0031] [31] The following description relates to an embodiment of the invention based on the development of the furnace described in the document EP-A-1 216 129 already mentioned. For more details concerning the characteristics and operation of the furnace, reference is usefully made to said literature. However, it is to be understood that the invention is not intended to be limited to the particular embodiments described.

[0032] [32] in figure 1 The oven shown schematically above comprises a plurality of oven modules 1, 2, 3, 4, the number of which depends on the travel speed of the products to be baked, which is determined by the speed of the production line located upstream and The product is determined by the necessary residence time for baking.

[0033] [33] Modules 1 , 2 , 3 , 4 are connected between them by means of joints that assemble their enclosures, with suitable thermal insulation pads 64 , 65 , 66 interposed.

[0034] [34] Gas burners 5, 6, 7, 8 are connecte...

Abstract

A continuous gas baking furnace comprising means for heating a baking area (29) through which the product which is to be treated passes, formed by at least one module (1, 2, 3, 4) comprising a heat exchanger (13, 14, 15, 16) with a gas burner (5, 6, 7, 8) and means (32, 33, 35, 36, 41, 42) for propelling and directing heated air towards a baking area (29), wherein the gas combustion circuit of the heat exchanger is separate from the circuit of hot air flowing through the baking area, the means for directing the hot air include paths (38,39) for directing hot air on both sides of the baking area (29) and a path (40) for evacuating air via the middle of the baking area. The invention is characterized in that it also comprises means for ensuring pyrolysis of gaseous effluents, said means treating a fraction of the gas circulating in a given section of the furnace, and at least one catalytic bed (76, 76') which is arranged on the hot air circuit.

Description

technical field [0001] [01] The present invention relates to ovens, and in particular to ovens for rubber articles. Background technique [0002] [02] Electric baking furnace is known, and its cost is medium, but the utilization cost is high. [0003] [03] It is also known to have a gas type baking furnace, which has a very large consumed power, and its technical disadvantages are as follows: [0004] [04] - Poor thermal insulation leads to useless consumption, [0005] [05] - Discharge of the fuel gases emitted by the gas burner through the heating flow, which poses a risk of contamination of the products to be baked, [0006] [06]-Using mechanical extraction, simultaneous discharge of baking steam from the product and combustion gas from heating, resulting in excessive energy consumption; this makes it necessary to discharge a large amount of hot air in order to extract the burned gas, even if the product has been no more baking steam, [0007] [07] - Irregular airflow...
