Abstract
A pilot burner () for a gas turbine engine delivers an inner non-swirling fuel-oxidant mixture surrounded by an outer swirling fuel-oxidant mixture, thereby providing enhanced mixing with no recirculation zone. At least one fluid-restricting inlet port () provides an oxidant to an inner mixing passage (). The inner mixing passage () includes a plurality of fuel outlets (). An outer annular mixing passage () receives oxidant from an upstream port () surrounding the inner mixing passage and includes at least one swirler element () and fuel outlets ().
