PROBLEM TO BE SOLVED: To obtain a shaft-type pyrolytic melting furnace in which a support gas fed from a tuyer surely flows without hindrance of refuse up to the lower layer of refuse which forms a melt zone, and spreads all over the lower part (melt zone), so as to prevent uneven melting of the refuse, and cause a stable melting reaction. SOLUTION: An angle protrusion 4 is formed on the furnace bottom, a narrowed opening 5 of a reduced inner diameter is formed above the protrusion. The lower layer of the refuse layer G is received at the reduced opening 5 to form a hollow 6 between the reduced opening and the furnace bottom face. The tuyer 3 is provided to the hollow to face to the protrusion. The support gas supplied from the tuyer ascends along the slant 40 of the protrusion.
