Patent ID: 8231730

Claim:
A burner for use in combustion deposition depositing a coating on a substrate, comprising: first and second spaced-apart combustion gas manifolds each comprising first and second walls configured to respectively produce first and second flames, the first and second combustion gas manifolds forming a precursor reaction zone therebetween; and an adjustable precursor delivery manifold located between the first and second combustion gas manifolds configured to receive a precursor used in forming the coating, the precursor delivery manifold being positioned so as to substantially directly provide the precursor to a predetermined portion of the precursor reaction zone, wherein the precursor delivery manifold includes first and second cooled side walls arranged to reduce the occurrence of precursor pre-reactions upstream of the precursor reaction zone, and wherein the first and second cooled side walls of the precursor delivery manifold are separate from the walls of the first and second combustion gas manifolds.
