Description

다수층 연소 보일러중의 질소산화물의 환원방법
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제 1 도는 두개의 유동층을 갖는 다수층 연소보일러의 수직단면도.
제 2 도는 세개의 유동층을 갖는 다수층 연소보일러의 수직단면도.

Claims (5)

  1. 연도가스중의 질소산화물의 환원을 위한, 한층이 다른층의 상부에 위치한, 최소한 두개의 유동층을 갖는 보일러에 암모니아가스의 공급방법에 있어서, 암모니아가스가 2차 공기 및/또는 3차 공기와 혼합된후 하부 유동층에서 상부 유동층으로 흘러들어가는 복수의 개별적인 연도가스기류에 공급되어져서 상부층 영역에 균등하게 분포되며, 이 상부층은 연도가스, 2차 공기 및/또는 3차 공기 및 이것들과 혼합된 암모니아 가스로 구성되는 가스기류에 의해 유동화됨을 특징으로 하는 방법.
  2. 제 1 항에 있어서, 2차 공기 및/또는 3차 공기와 암모니아 가스와 혼합물은 공기 흐름에 맞게 조절됨을 특징으로 하는 방법.
  3. 제 1 항에 있어서, 2차 공기 및/또는 3차 공기와 암모니아 가스의 혼합물은 연도가스 온도에 맞게 조절됨을 특징으로 하는 방법.
  4. 제 1 항에 있어서, 혼합된 암모니아가스의 양은 질소 산화물의 함량, 공기흐름 및 연도가스 온도에 맞게 조절됨을 특징으로 하는 방법.
  5. 제 1 항에 있어서, 혼합된 암모니아가스의 양은 배출되는 연도가스에 남아있는 양으로 제한됨을 특징으로 하는 방법.
