Effects of Fuel-Air Unmixedness on Lean Premixed Combustion Characteristics
연료-공기 비혼합도가 희박예혼합 연소 특성에 미치는 영향
Abstract
The lean premixed technique has been proven very efficient in reducing NOx emissions from gas turbine combustors. However combustion instability is susceptible to occur in lean premixed combustor. So laboratory-scale dump combustor was used to understanding the underlying mechanisms causing combustion instabilities. In this study, tests were conducted at atmospheric pressure and inlet air was up to
