Annular type gas turbine combustor

摘要

Provided is an annular type gas turbine combustor of high reliability which can regulate air flow distribution without being influenced by high temperature flames and with a desired fuel-air ratio being obtained to reduce generation of NOx etc. A side duct (10) for regulating air flow distribution is disposed slidably in axial direction at a terminal end of a pre-dissuer (1) and as the slide duct (10) is moved, air flow supplied downstream to a swirler (4) is regulated so as to obtain a desired fuel-air ratio. <IMAGE>
