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.
Claims15
A nozzle comprising a front section having a length and a face, a back section joining with a source of a gas from the group consisting of fuel, oxidant, nitrogen, argon and carbon dioxide, at least one passageway suitable for the passage of a first portion of said gas through the length at a velocity greater than 100 feet per second, and said front section comprising porous material which enables a second portion of said gas to pass through the porous material and out from the nozzle across the face.
A method for injecting gas into a receiving zone comprising:
- (A) providing a nozzle comprising a section having a length and a face, a passageway through the length, and said section comprising porous material,
- (B) passing a portion of a gas from the group consisting of fuel, oxidant, nitrogen, argon and carbon dioxide through the passageway and into the receiving zone at a velocity greater than 100 feet per second;
- and
- (C) passing another portion of said gas through said porous material and into the receiving zone at the face.
A nozzle comprising a front section having a length and a face, a back section joining with a source of a gas from the group consisting of fuel, oxidant, nitrogen, argon and carbon dioxide, a single passageway suitable for the passage of a first portion of said gas through the length at a velocity greater than 100 feet per second, and said front section comprising porous material which enables a second portion of said gas to pass through the porous material and out from the nozzle across the face.
