Abstract

예비 혼합동작모드에서 터어빈용 연소기 동작방법은 연소기를 통과한는 비대칭 연료형태를 제공하기 위해서 환상 대칭 배열의 연료 노즐을 통해 연료를 공급하는 단계를 포함한다. 이 비대칭 연려 흐름은 확산동작모드와 예비혼합동작 모드 사이의 변이과정 이전에 확산 동작모드 동안, 변이과정 동안 및 예비 혼합동작모드 동안에 제공된다. 전 동력 근방에, 연료는 예비 혼합 동작모드에서 동작하는 연료노즐 사이에 동일하게 공급된다. 이 비대칭 연료흐름은 연소기를 안정화시키고 높은 소음 진폭 연소 소음을 방지하는 한편 예비혼합 동작모드에서 동작하는 낮은 배기 가스 방출을 달성한다.
