Claims (4)

  1. 연소기(11)에 도시 고형폐기물을 장입하는 단계와고형폐기물을 연소시켜서 비산회를 함유하는 배기가스를 발생시키는 단계를 포함하는 도시 고형폐기물의 연소시에 생성된 독성화합무의 파괴방법에 있어서, 상기 폐기물은 충분히 높은 온도에서 연소되어 배기가스중의 독성화합물을 파괴시키고, 상기 비산회는 배기가스중에서 파괴되지 않거나 재구성된 독성 화합물을 상기 비산회에 의해 흡착 및 화학적 흡착이 일어날 수 있는 온도로 냉각시키고, 독성화합물이 흡착된 상기 비산회를 회수하고, 독성 화합물이 흡착된 상기 비산회중 적어도 일부를연소기(11)로 재순환시켜서 독성화합물을 파괴시키는것을 특징으로 하는 방법.
  2. 제1항에 있어서, 연소기(11)의 온도가 적어도 980℃인 것을 특징으로 하는 방법.
  3. 제1항에 있어서, 배기물 및 비산회가 연소기(11)내에 생성된 후, 배기물중의독성가스가 흡착 및 화학적 흡수되도록 비산회를 400℃ 또는 그 이하의 온도에서 수집하는 것을 특징으로 하는 방법.
  4. 제1항에 있어서, 비산회에 의한 독성화합물의 흡착이 억제됨과 동시에 비산회상의 독서화합물이 파괴되도록 온도가 980℃ 이상인 부위로부터 비산회를 제거하는 것을 특징으로 하는 방법.
    ※ 참고사항 : 최초 출원 내용에 의하여 공개하는 것임.
