摘要： PROBLEM TO BE SOLVED: To provide a carbon fiber production apparatus which can stably perform a flameproof treatment to obtain a carbon fiber having high quality, and to provide a method for producing the carbon fiber.
SOLUTION: The carbon fiber production apparatus includes: a flameproof oven 1 for circulating a hot gas to subject a precursor fiber bundle to a flameproof treatment; a carbonization oven (not shown in the figure) for carbonizing the flameproof fiber subjected to the flameproof treatment in the flameproof oven 1; a heat exchanger (the second heat exchanger 26) for performing heat exchange between an exhausted gas sent from the flameproof oven 1 or the carbonization oven and an outer air; and a heated outer air-supplying route 32 for supplying the heated outer air sent from the heat exchanger to the flameproof oven 1. The apparatus includes a temperature detection means 35 for detecting the temperature of the heated outer air flowing in the heated outer air-supplying route 32, and a temperature adjustment means (outer air bypass route 33 and automatic valve 34) for adjusting the temperature of the heated outer air flowing in the heated outer air-supplying route 32.
