Abstract
An injector mixer for a gasification reactor system that utilizes reactants includes an injector body that extends between a first face and a second face. The injector body includes a first passage that extends between the first face and the second face and has a first central axis. At least one second, impinging passage extends between the first face and second face and has an associated second central axis that has an angle with the first axis. The angle satisfies mixing efficiency Equation (I) disclosed herein.
