With the above configuration of the air supply pipe 6 of the auxiliary combustion apparatus, even when air is supplied from the lateral direction to the air flow path in the vertical direction of the air supply pipe 6, the auxiliary combustion apparatus 7 can be used. Combustion can be performed uniformly. When the air is supplied into the air supply pipe 6 of the auxiliary combustion device 7 from sufficiently below, the eccentric opening member 80 described above is unnecessary.

FIG. 7 shows another example of the auxiliary combustion device according to the second preferred embodiment of the present invention by a longitudinal sectional view (a partial sectional view showing a longitudinal section of the dry distillation chamber and the auxiliary combustion device). In FIG. 7, the portion of the fuel supply hole 5 is shown by a side view. In FIG. 7, 90A is a supply hole for the auxiliary combustion device 7 for combustion air, 91a is a supply hole 90A forming member, and 91b is a supply hole 9A.
