Abstract
A precombustor system () including an ignition chamber () having a front wall (), a central axis, a diameter D, and an outlet () configured to discharge a product gas (). The ignition chamber () includes a central ignition oxygen injector () configured to inject a first oxygen stream from the front wall () substantially parallel to the central axis, and a tangential primary fuel injector () configured to inject a primary fuel stream tangential to the central axis at a location an axial distance Xdownstream of the front wall (). The ratio X/Dis from 0.25 to 4.0. The central axis forms an angle a with a vertical line of less than or equal to about 45 degrees. The trajectory of the primary fuel stream forms an angle θ with a plane that is perpendicular to the central axis of less than or equal to about 20 degrees. A method for combustion is also disclosed.
