Claims (11)

  1. 제1유동층(11)과 제2유동층(12)이 서로 분리되나, 서로 연락되며, 연료입자가 제1층(11)에서 제2층(12)으로 전달되고, 제1유동층(11) 및, 제1유동층의 옆에 놓인 제2유동층(12)에서 고체연료를 연소하는 방법에 있어서, 두층으로부터의 연도가스를 효율적으로 혼합하고, 제1층의 연도가스로부터의 입자들을 제2층으로 공급하기 위해서, 층들위의 공통 프리보오드에 있는, 준화학양론적으로 작동되는 제1층으로부터의 연도가스가 과량의 공기와 함께 작동하는 제2층으로 향해지며, 화력이 단지 제2층으로부터의 열교환에 의해서 회수됨을 특징으로 하는, 제1유동층과 제2유동층에서 고체연료를 연소시키는 방법.
  2. 제1항에 있어서, 과립물질이 제2유동층의 바닥에서 제1유동층의 바닥으로 전달됨을 특징으로 하는 제1유동층과 제2유동층에서 고체연료를 연소시키는 방법.
  3. 제2항에 있어서, 제1유동층의 냉각이 두층사이에 과립물질의 흐름을 조절함으로써 변화됨을 특징으로 하는 제1유동층과 제2유동층에서 고체연료를 연소시키는 방법.
  4. 제2또는 제3항에 있어서, 과립물질이 제1유동층(11)으로 부터 제2유동층(12)으로 넘처흐를 수 있음을 특징으로 하는 제1유동층과 제2유동층에서 고체연료를 연소시키는 방법.
  5. 제1항에 있어서, 두층으로부터의 연도가스에서 분리된 먼지가 제1층(11)으로 재순환됨을 특징으로 하는, 제1유동층과 제2유동층에서 고체연료를 연소시키는 방법.
  6. 제1항에 있어서, 제1유동층에서의 공기속도가 제2유도층에서의 공기속도보다 훨씬 더 큼을 특징으로 하는 제1유동층과 제2유동층에서 고체연료를 연소시키는 방법.
  7. 제6항에 있어서, 제2유동층(12)의 열회수는, 열교환기(17)에 대해서 제2유동층(12)의 수준을 조정함으로써 조절됨을 특징으로 하는, 제1유동층과 제2유동층에서 고체연료를 연소시키는 방법.
  8. 제1또는 7항에 있어서, 제2유동층(12)에서의 열회수는 층에 온도수준을 조정함으로써 조절됨을 특징으로 하는 제1유동층과 제2유동층에서 고체연료를 연소시키는 방법.
  9. 제1항에 있어서, 연료가 제1층의 상부로부터 제1층(11)에 공급됨을 특징으로 하는 제1유동층과 제2유동층에서 고체연료를 연소시키는 방법.
  10. 제1항에 있어서, 연도가스와 혼합된 공기가 제1유동층(11)에 공급됨을 특징으로 하는 제1유동층과 제2유동층에서 고체연료를 연소시키는 방법.
  11. 제1항에 있어서, 공기가 여러가지 수준에서 제1층(11)에 공급되며, 제1층의 상부에서의 공기흐름이 제1층의 상부에서의 공기흐름이 제1층의 하부에서의 공기흐름보다 더 큼을 특징으로 하는 제1유동층과 제2유동층에서 고체연료를 연소시키는 방법.
