Ultra-Low NOx Rich-Lean Combustion [PDF]
Volume 3: Coal, Biomass and Alternative Fuels; Combustion and Fuels; Oil and Gas Applications; Cycle Innovations, 1990 An investigation has been carried out of the influence of the geometry and operating parameters of the rich/quench/lean (RQL) combustion concept on the NOx emissions. The RQL combustor is a three stage, variable geometry system in which fuel is burned in a carefully controlled fuel rich and fuel lean environment. The data utilized in this investigation
