Claims (4)
- 固体燃料を部分燃焼させて可燃ガスとスラグを生成するガス化部と、該ガス化部から落下するスラグを冷却水により冷却するスラグ冷却部と、該スラグ冷却部からスラグが移動するスラグロックホッパと、該スラグロックホッパからのスラグを水と分離して排出するスラグ分離槽とを備え、
前記スラグロックホッパの底部には重力方向に延在してなる配管の上端が接続され、該配管の下端が前記スラグ分離槽に貯留された水の液面より下方で開口され、前記配管に気体を注入する気体注入管が接続されているガス化処理装置。 - 前記気体注入管により注入される気体量を増減して前記スラグロックホッパから前記スラグ分離槽に移動させるスラグの分量を可変制御する手段を有したことを特徴とする請求項1に記載のガス化処理装置。
- 固体燃料の部分燃焼により生成されるスラグをスラグ冷却部内の冷却水により冷却し、該冷却されたスラグをスラグロックホッパに移動し、該スラグロックホッパ内のスラグをスラグ分離槽に移動させるガス化処理方法であって、
前記スラグロックホッパから前記スラグ分離槽へのスラグの移動は、前記スラグロックホッパを大気圧下に開放した状態とし、前記スラグ分離槽に貯留された水の液面に受圧された圧力を前記スラグロックホッパ内に充填された水の部分に伝達させた状態で、前記スラグロックホッパの底部に連結され重力方向に延在した配管内に気体を注入して行われることを特徴とするガス化処理方法。 - 前記スラグロックホッパ内のスラグをスラグ分離槽に移動させる前に、そのスラグロックホッパの底部に連結され重力方向に延在した配管内に気体を注入して貯留させることを特徴とする請求項3に記載のガス化処理方法。
