Popis:	An advanced diffusion combustor combinig branced air nozzles and branched fuel nozzles is proposed. This type of combustor is expected to be more effective for improvig fuel/air mixing in the combustion chamber than a single-hole air-nozzle diffusion combustor. In this study, nozzle diameter is kept constant, while the angles of fuel nozzles are varied. Three kinds of combustors having fuel nozzle angles of 30°, 45°and 60°are used. For each combustor, deviation angle between air and fuel nozzles is set to be 0°, 15°and 45°, respectively. The results show that the optimum flamestability is obtained for a fuel/air nozzle deviation angle of 45°and it is unrelated to fuel nozzle angle. Furthermore, flame stability limits are much higher than those of coaxial burners.
