Abstract
Official abstract text for this publication.
According to one aspect of the invention, a riser includes a cylindrical housing defined by a sidewall having an interior surface and an exterior surface. A baffle is defined by a first segment and a second segment, wherein the baffle is designed to be positioned on the interior surface of the riser and wherein the first segment and second segment are releasably interlockable.
First claim
Opening claim text (preview).
We claim: 1. A conduit, comprising: a cylindrical housing defined by a sidewall having an interior surface and an exterior surface; a baffle defined by a first segment and a second segment, wherein the baffle is designed to be retrofitted and positioned on the interior surface of the conduit on top of a refractory layer and wherein the first segment and second segment are releasably interlockable; and wherein the baffle includes a lower surface characterized by an angle in relation to the interior surface of the sidewall, and wherein the baffle is designed to be sealingly flush with the interior surface of the cylindrical housing or to be disposed within a groove disposed in the interior surface of the sidewall. 2. The conduit of claim 1 , wherein the lower surface is characterized by an angle between about 30 to about 50 degrees in relation to the interior surface of the sidewall. 3. The conduit of claim 1 , wherein the baffle includes an upper surface disposed opposite of the lower surface. 4. The conduit of claim 3 , wherein the upper surface is characterized by a second angle between about 10 to about 50 degrees in relation to the interior surface of the sidewall. 5. The conduit of claim 4 , wherein the upper surface is characterized by a radius of curvature. 6. The conduit of claim 1 , wherein the first segment of the baffle includes a groove. 7. The conduit of claim 6 , wherein the groove is disposed at an end thereof. 8. The conduit of claim 7 , wherein the second segment of the baffle includes a ridge. 9. The conduit of claim 8 , wherein the ridge of the second segment is designed to be positioned within the groove of the first segment when the baffle is disposed within the conduit.
