Claims (3)

  1. 미분석탄로의 연소배기 가스중에 산화질소 및 산화황의 함량을 감소시키는 방법으로서, 로내로 공급되는 연료-공기류를 연료의 농도가 높은 기류와 연료의 농도가 낮은 기류로 분리시키고, 연료의 농도가 높은 기류는 제1부분으로 공급시키며, 제1부분에 불충분한 량의 공기를 공급하여 연료의 농도가 높은 기류의 모든 연료의 완전연소를 촉진시키고, 연료의 농도가 낮은 기류는 제2부분으로 공급하며, 제2부분에 충분한 양의 공기를 공급하여 두 기류의 모든 연료의 완전연소를 촉진시킴으로서 연소가스 중에 산화질소 및 산화황의 생성을 극소화시키는 것을 특징으로 하는 산화 질소 및 산화황 방출 감소법.
  2. 제1항에 있어서, 로내로 공급되는 연료와 함께 석회를 로내에 공급하는 것을 특징으로 하는 산화질소 및 산화황 방출감소법.
  3. 제1항 또는 제2항에 있어서, 제2부분에 공급되는 공기는 로내에서 연료의 완전연소에 필요한것보다 많은 량인 것을 특징으로 하는 산화질소 및 산화황 방출감소법.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
