Abstract
Plural first exhaust pipes are disposed as exhaust paths at an upper portion of a heat treatment apparatus. Exhaust gases are discharged from the inside of the heat treatment apparatus to the respective exhaust pipes. Inlets of catalyst units are connected to outlets of the first exhaust pipes, and second exhaust pipes are connected to outlets of the catalyst units. Exhaust gases are discharged from exhaust ports of the second exhaust pipes to the outside (e.g., the atmosphere) of the heat treatment apparatus.
