Abstract
A nozzle and gas injection method using the nozzle wherein the nozzle comprises a section of porous material. Gas passes through one or more passageways running the length of the porous material section and also diffuses through the porous material section exiting across the nozzle face. This gas passing through the face serves to keep deleterious material, such as zone vapors, from contacting and fouling the nozzle.
