Description
また、二次燃焼部が出滓口より下方にあるときのみならず上方にあっても、灰溶融炉と二次燃焼部とを連通するダクトを大きく上方に立ち上げることなく設置でき、灰溶融炉に排ガス取り出し口を設けずに排ガスを取り出すことができる。したがって、灰溶融炉の炉内耐火材に排ガス取り出し口の穴を設けずに済み、そのため耐火材の耐久性が増す。また、ダクトは水平面を有さないので同ダクトに飛灰が堆積して閉塞するのが防止される。
スラグは1400℃以上の温度で、出滓口20から連続出滓される。ここで図1の出滓口20、出滓樋21付近の拡大図を図2に示す。出滓口20はスラグやメタルを出滓する灰溶融炉3の側壁下部に設けられた開口部である。出滓口20からは出滓樋21が下方に延び、灰溶融炉内のスラグやメタルは出滓口20、出滓樋21を通り冷却水槽7に落ちる。本実施例における灰溶融炉3は、傾動により炉内底部に溜まったメタルを出滓口20から出滓する。傾動は、傾動装置18が灰溶融炉3を傾動軸19を回転中心にして灰溶融炉3を傾けることをいう。
