る。(Prior Art) A conventional coal gasification furnace (one-stage spouted bed type) is shown in FIG. In FIG. 3, a refractory heat insulating material 22 having a thickness of 100 to 150 mm or more is provided inside the pressure vessel 21, a gasification furnace 23 is provided in the upper portion, and a cooler 24 is provided in the lower portion. A supply means 25 for supplying coal, oil, air, or oxygen is provided above the gasification furnace 23.
Is placed in the cooler section 24.

出される。When starting the apparatus, oil and air or oxygen are supplied from the supply means 25 into the gasification furnace 23 and burned to perform warming. The gasification furnace 23 has a predetermined temperature, for example, 14 degrees Celsius.
At 00 degrees, it gradually switches from oil to coal. When switched to coal, the supply of air or oxygen is reduced, and the coal is incompletely burned to produce combustible gases such as CO and H 2 gas. The flammable gas enters the cooler section 24 from the gasification furnace 23,
Here, it is cooled to about 1000 to 1100 degrees Celsius by the radiant cooler 26. The gas cooled to about 1000 to 1100 degrees Celsius exits from the gas outlet 27 and is sent to the heat exchanger. The slag generated in the gasification furnace 23 passes through the cooler section 24 and drops into the ash hopper 28, and is discharged from the discharge port below the ash hopper 28.
このような従来の１段噴流床式石炭ガス化炉において
は灰の溶融流出を確保するため、炉全体を高温に維持す
る必要がある。このため次のような欠点が生ずる。In such a conventional one-stage spouted bed coal gasification furnace, it is necessary to maintain the temperature of the entire furnace at a high temperature in order to secure the melting and outflow of ash. Therefore, the following drawbacks occur.
炉全体として空気または酸素投入量を増加させて温
度を高く保つためガス化効率が悪い。高い発熱量のガス
が得にくいため酸素によるガス化が不可欠となる。Gasification efficiency is poor because the temperature of the entire furnace is increased by increasing the amount of air or oxygen input. Gasification with oxygen is indispensable because it is difficult to obtain a gas with a high calorific value.
圧力容器に熱が伝わらないように厚い耐熱・耐火材
（一般に100〜150mm以上）を使用しているため放熱量が
低く、耐熱・耐火材は炉内と同一温度になるので寿命が
短い。このため炉の温度をあまり高くできないので灰の
融点の高い石炭にはなじまない。即ち炭種適合性におと
る。A thick heat-resistant / refractory material (generally 100 to 150 mm or more) is used to prevent heat from being transferred to the pressure vessel, resulting in low heat dissipation. The heat-resistant / refractory material has the same temperature as in the furnace, so its life is short. For this reason, the temperature of the furnace cannot be raised so high that it is not suitable for coal with a high melting point of ash. That is, it is compatible with coal type.
熱交換器入口のガス温度を灰の軟化温度以下に制御
するためには水クエンチによる冷却あるいはラデイアン
トボイラによる水側への放熱が不可欠であり、その分ガ
ス化効率が悪くなるという欠点を持つ。In order to control the gas temperature at the heat exchanger inlet below the softening temperature of ash, cooling by water quenching or heat radiation to the water side by the radiant boiler is indispensable, and gasification efficiency deteriorates accordingly. .
更に耐圧容器内面に直接耐火断熱材を施工し水冷壁
を有しない場合には耐火材の厚みが大きくなり、起動の
ウオーミングに長時間を要するとともに負荷変動時にお
いても制約が生ずることとなるという欠点を有する。Furthermore, when the refractory insulation is applied directly to the inner surface of the pressure vessel and there is no water-cooling wall, the thickness of the refractory becomes large, and it takes a long time to warm up the start-up, and restrictions occur even when the load changes. Have.
