A thermal processing system with improved gas flow and method for injecting a process gas into a thermal processing system. The thermal processing system has an injection section with injection outlets that inject process gas into a processing space and a delivery section that delivers process gas to the injection section. The delivery section may be coupled with the injection section at an inlet disposed between opposite ends of the injection section. A fluid lumen of the injection section may have a larger cross-sectional area than a fluid lumen of the delivery section. The thermal processing system may include an inner tube, which surrounds the processing space, having a slit through which the processing space communicates with an annular pumping space defined between the inner tube and an outer tube of the thermal processing system.
