제1도는 석탄애쉬(ashes)에서 측정된 황 억류와 연소된 석탄에서 황에 대한 칼슘의 몰비 사이의 연관성을 보여주는 ASTM애쉬자료의 도면이다. 제2도는 낮은 NOx/SOx버너에서 연소된 아역청탄에 대한 CaO/AL2O3/SiO2의 삼각좌표이다. 제3도는 낮은 NO(SO(버너에서 연소전 및 연소후의 역청탄에 대한 CaO/AL2O3/SiO2의 삼각좌표이다.

Claims (12)

  1. 하기과정에 의한 황함유연료의 연소방법：(a)황 함유연료, 황결합물질 및 황억류 물질의 혼합물을 일차 연소구역에 도입하고；(b)상기의 거의 모든 황이 상기의 황 결합 물질에 의해 고체형태로 포획되고, 그 포획된 황이 황억류물질에 결합하는 온도에서, 화학량론적으로는 연료가 농후되는 조건하에 상기 혼합물을 그일차 연소 구역에서 연소시킴으로써, 연료가 농후한 가스와 고체 황 함유 플라이 애쉬 및 슬랙이 함유된 연소 생성물을 얻으며；(c)황과 그 결합물질과 고체 형태로 그 황을 보유하기 위한 억류물질 사이의 상호 작용을 더욱 유도하기 위하여, 적어도 하나의 다른 부수적인 연료농후 연소 구역에서 황 결합물질에 의한 황 포획이 열역학적으로 불리한 조건 및 그 고체물질의 융해점 이상의 온도하에 상기의 연소 생성물을 연소시킨다.
  2. 제1항에 있어서, 상기 황결합 물질이 칼슘 화합물인 연소방법.

  4. 제2항에 있어서, 황에 대한칼슘의 총몰비가 1.5：1-2.5：1의 범위인 연소방법.
  5. 제1항에 있어서, 황결합물질이 하나이상의 기본성분을 포함하고, 그 혼합물에 있어서 황에 대한기본성분의 몰비가 2：1인 연소방법.
  6. 제1항에 있어서, 상기 황억류 물질이 실리콘 화합물 및 실리콘 화합물과 알루미늄 화합물의 혼합물로부터 선택되는 연소방법.
  7. 제6항에 있어서, 황 포획에 관련된 칼슘에 대한 실리콘의 몰비가 0.6내지 1.2인 연소방법.
  8. 제6항에 있어서, 황 포획에 관련된 칼슘에 대한 실리콤의 몰비가 0.8내지 1.0인 연소방법.
  9. 제1항에 있어서, 나트륨이 상기 혼합물에 존재하고, 상기 나트륨이 또한 상기 일차 및 이차 구역에서 고체 형태로 포획 및 억류되는 연소방법.
  10. 제1항에 있어서, 상기 황 결합물질의 적어도 일부분이 본래부터 상기 석탄에 존재하는 연소방법.
  11. 제1항에 있어서, 상기 황억류 물질의 적어도 일부분이 본래부터 상기 석탄에 존재하는 연소방법.
  12. 제5항에 있어서, 상기 기본성분이 마그네슘 및 칼슘인 연소방법.
