REACTOR FEED NOZZLES
Improved reactor feed nozzles are disclosed. According to one embodiment, a feed nozzle comprises an inner tubing encased within an outer heat shield tubing, a first circular hole fabricated in the inner tubing, the first circular hole having a first diameter and serving as a discharge hole, a second circular hole fabricated in the outer heat shield tubing, the second circular hole having a second diameter, wherein the second diameter is larger than the first diameter; and a welded tip for extending a flow path at a declining angle, the welded tip having a section extending at a predetermined angle from the inner tubing to the discharge hole.
1 . A feed nozzle, comprising:
an inner tubing encased within an outer heat shield tubing;
a first circular hole fabricated in the inner tubing, the first circular hole having a first diameter and serving as a discharge hole;
a second circular hole fabricated in the outer heat shield tubing, the second circular hole having a second diameter, wherein the second diameter is larger than the first diameter; and
a welded tip for extending a flow path at a declining angle, the welded tip having a section extending at a predetermined angle from the inner tubing to the discharge hole.
2 . The feed nozzle of claim 1 , wherein the feed nozzle is inserted perpendicularly into a tubular reactor.
3 . The feed nozzle of claim 1 , wherein the inner tubing is stainless steel.
4 . The feed nozzle of claim 1 , wherein the outer heat shield tubing is stainless steel.
5 . The feed nozzle of claim 1 , wherein the predetermined angle is 90°.
6 . The feed nozzle of claim 1 , wherein the predetermined angle is 45°.
7 . The feed nozzle of claim 1 , wherein the discharge hole is shaped according to an 8-sided star pattern.
8 . The feed nozzle of claim 1 , wherein the discharge hole is oval.
9 . The feed nozzle of claim 1 , wherein the section is vertical.
10 . The feed nozzle of claim 1 , wherein the section is diagonal.
11 . The feed nozzle of claim 1 , wherein the inner tubing has a liquid feed path and a gas feed path.
