Air is supplied from the supply groove 21 and combustion occurs.
本考案は叙上の如く固定ロストルの外周縁上に
環状の回転ロストルを載承したので、回転ロスト
ルの回転により固定ロストル外周部に達した燃料
から灰層を除去することができる。 As described above, in the present invention, the annular rotating roistle is mounted on the outer periphery of the fixed roistle, so that the ash layer can be removed from the fuel that has reached the outer periphery of the fixed roistle by rotation of the rotary rooster.

炎の中芯部、すなわち燃料供給口の直上に揮発室
（乾留室）を形成し得る。 In addition, since an air supply groove is provided in the fixed rooster between the fuel supply port and the outer periphery of the rooster, the outer periphery of the fuel supply port can be used as a combustion surface, and the solid fuel can be burned on the upper surface to create a combustion flame. A volatilization chamber (carbonization chamber) can be formed at the center of the flame, that is, directly above the fuel supply port.
従つて、上記灰層の除去と揮発室の形成によつ

らに助成することができる。 In addition, since the air supply groove is made radial, the supply air rises uniformly over the entire circumference of the rooster, minimizing the fluctuation of the combustion flame, and furthermore, there is no space between the inner end of the air supply groove and the fuel supply port. Since the gap is left, combustion does not proceed to the inside of the fuel supply port, and the volatilization chamber can be stabilized and reliably formed, thus further promoting complete combustion of the solid fuel and improvement of combustion efficiency. Can be done.
