A system includes a gasifier configured to gasify a feed to generate syngas. The gasifier comprises a first axis. The system also includes a first gasification reaction zone disposed in the gasifier. The first gasification reaction zone is defined at least partially by a first wall substantially perpendicular to the first axis. The system also includes a first feed injector coupled to the gasifier. The first feed injector is configured to inject the feed into the first gasification reaction zone beneath the first wall in a first direction relative to the first axis.
