FUEL INJECTOR AND PREMIXER SYSTEM FOR A BURNER ARRAY

A fuel injector and micromixer system includes: a mixing element tube configured to mix air and fuel prior to injection into a combustor; an injector positioned within the mixing element tube, the injector configured to inject a fluid into the mixing element tube; one or more air inlet slots, the one or more air inlet slots being positioned on one or more sides of the injector; one or more fuel injection holes configured to inject fuel into the mixing element tube; and one or more delta wing vortex generators positioned within an inner wall of the mixing element tube, the one or more delta wing vortex generators configured to generate a vortex pair that accelerates mixing of air and fuel injected into the mixing element tube. Additional air slots may be provided downstream of the delta wing vortex generator to excite a pair of vortices or lift off fuel to prevent flame retention. 一种燃料注入器和微型混合器系统，包括：混合元件管，混合元件管被构造为在将空气和燃料注入到燃烧器中之前混合空气和燃料；注入器，注入器定位在混合元件管内，注入器被构造为将流体注入到混合元件管中；一个或多个空气入口槽，一个或多个空气入口槽定位在注入器的一侧或多侧；一个
