Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a piping structure of an open-fire furnace in a continuous annealing furnace with which as the piping structure of the open-fire furnace in the continuous annealing furnace, the stickness of foreign matters to a heat-treating material can be restrained and also, a cost of facility investment can be reduced. SOLUTION: As the piping structure of the open-fire furnace 20 in the continuous annealing furnace, filters 2 are set in the fuel gas piping for open-fire heating burner 15, and the up-stream side of the filter 2 is used with a general carbon steel pipe 1 and the down-stream side of the filter 2 is used with SUS (stainless steel) piping 3.
