摘要：PROBLEM TO BE SOLVED: To provide an apparatus for flameproof treatment of an acryl fiber bundle, by which the cost for the flameproof treatment is extremely reduced without using electricity as a heat source, and the temperature distribution in a treating chamber can be reduced. SOLUTION: The apparatus for the flameproof treatment carries out the flameproof treatment of the acryl fiber bundle by an oxidative gas while circulating the heated oxidizing gas. The apparatus has a combustion chamber including a burner as an oxidizing gas heating means, and an exhaust gas chamber communicating with the combustion chamber through a heat-transfer part. The apparatus is also equipped with a heater array constituted of at least two heaters at least carrying out heating at the heat transfer part by the exhaust gas generated by the combustion of a fuel by the burner, and sent from the combustion chamber through the heat-transfer part to the exhaust gas chamber, and at least two of the heaters are arranged so that the directions of the exhaust gas flowing in the heat-transfer part may be opposite to each other between the heaters.
