    • In order to stably maintain a combustion capability in a combustion furnace for coal gassification, it is necessary to exhaust molten slag produced within the furnace without the slag stagnating. The present invention provides, in a combustion furnace for coal gassification, a slag exhausting device which is configured in such a manner that the cooling of molten slag being exhausted from the furnace is minimized to prevent the slag from solidifying and causing other slag to stagnate. The slag exhausting device is disposed at the center of a bottom wall of the combustor, and has a lower cylindrical portion and an upper bank opening upwardly and flared at an angle of 300.degree.-45.degree.. The height H from the bottom wall to the top of the upper bank, a height L and an inner diameter ds of the cylindrical lower portion and a diameter D of the combustor are set to satisfy the relations of ds/D=0.2-0.4, L/ds=0.2-0.6 and H/D=0.05-0.15.
    • 为了稳定地保持用于煤气化的燃烧炉中的燃烧能力,需要排出炉内产生的熔渣而不会使炉渣停滞。 本发明在用于煤气化的燃烧炉中提供一种排渣装置,该炉渣排出装置被构造成使得从炉排出的熔渣的冷却最小化,以防止炉渣固化并导致其它炉渣停滞。 炉渣排出装置设置在燃烧器的底壁的中心,具有下圆筒部和上堤开口向上并以300°-45°的角度张开。 从顶壁到顶部的高度H,圆柱形下部的高度L和内径ds以及燃烧器的直径D设定为满足ds / D = 0.2-0.4的关系, L / ds = 0.2-0.6,H / D = 0.05-0.15。
