Development of dry low NO_x combustionsystem for 1.5MW gas turbine cogeneration system

摘要

Development of the dry low NO_x combustor for 1.5MW industrial gas turbine is described.Alean pre-mix and multiple burners design was tested on a bench-scale can combustor using naturla gas for fuel.Effects of key design variables on combustion characteristics were evaluated.The key design variables include the air flow distribution within the combustor ,injector position relative to the swirler,and air/fuel distribution.Emission values obtained by the optimization of these design parameters were NO_x<10 ppm (at 15
