Abstract
A gas injection apparatus for injecting a quench gas. The gas injection apparatus provides a means for injecting a quench gas into a hot gas contained in a vessel having an inner liner. The apparatus is designed such that the independent thermal expansions and contractions of the inner liner do not create excess thermal stresses on an expansible supply duct. The expansible supply duct provides the means for transferring the gas from outside the vessel into the gas stream. A plenum assembly, creating an interface between the expansible supply duct and the inner liner is sealably attached to the inner liner allowing perpendicular injection of the quench gas while maintaining the liner's integrity.
Claims11
A gas injection apparatus in combination with a lined vessel wherein said lined vessel includes a vessel wall and an inner liner, said inner liner comprising a series of parallel tubes radially joined together by web members, said inner liner being spaced apart from the vessel wall and having an inner surface and an outer surface, said gas injection apparatus comprising at least one plenum assembly sealably attached to the outer surface of the inner liner;
- the inner liner having openings positioned and arranged to provide communication between the interior of the vessel and the area defined by said plenum assembly and the inner liner for injection of gas into the interior of said vessel perpendicularly to the plane of the inner liner;
- said gas injection apparatus further comprising an expansible supply duct attached to and extending between the vessel wall and said plenum assembly.
A gas injection apparatus in combination with a lined vessel having a vessel wall and an inner liner spaced apart from the vessel wall;
- wherein said inner liner comprises a series of parallel tubes radially joined together by web members to form a cylinder having an outer surface;
- said gas injection apparatus comprising at least one plenum assembly sealably attached to said outer surface;
- said inner liner having openings positioned and arranged to provide communication between the interior of the vessel and the area defined by said plenum assembly and said inner liner such that a gas may be injected into the interior of said vessel perpendicularly to the plane of said inner liner;
- said gas injection apparatus further comprising an expansible supply duct having an outer end passing perpendicularly through said vessel wall, an inner end sealably attached perpendicularly to said plenum assembly, and a spool piece connecting said outer end and said inner end, such that the longitudinal axis of said spool piece is parallel to said inner liner;
- wherein said spool piece comprises at least one bellows section.
