Abstract
A nozzle reactor includes a passage having one or more regions with a converging-diverging shape. The nozzle reactor accelerates a reacting fluid to supersonic velocities and mixes it with a feed material. The reacting fluid and the feed material may be pre-heated. The high speed collision between the reacting fluid and the feed material at elevated temperatures causes the materials to react.
Claims18
A nozzle reactor comprising:
- a main passage including a first region followed by a second region, the first region and the second region each including a convergent section, a throat, and a divergent section;
- and
- a feed passage in fluid communication with the main passage;
- wherein the feed passage meets the main passage between the throat in the first region and the throat in the second region and wherein the main passage expands between the location where the feed passage meets the main passage and the throat in the second region thereby defining an expansion area;
- and
- a distributor positioned in the feed passage, the distributor being configured to annularly distribute flow from the feed passage to the main passage.

A nozzle reactor comprising:
- a main passage including a convergent section, a throat, and a divergent section;
- a feed passage in fluid communication with the main passage at a location downstream of the throat;
- a distributor positioned in the feed passage, the distributor being configured to annularly distribute flow from the feed passage to the main passage;
- and
- a wear ring through which the main passage passes, the wear ring being positioned immediately adjacent to and downstream of the location where the feed passage meets the main passage;
- wherein the wear ring is a physically separate component, whereby the wear ring is capable of being removed from the nozzle reactor and replaced;
- wherein the main passage expands downstream of the location where the feed passage is in fluid communication with the main passage thereby forming an expansion chamber.
4 more elements
A nozzle reactor comprising:
- a main passage including a convergent section, a throat, and a divergent section;
- a feed passage in fluid communication with the main passage downstream of the throat;
- a reacting fluid flowing through the main passage;
- a feed material flowing through the feed passage to the main passage;
- a distributor that receives the feed material and distributes it annularly and approximately uniformly into contact with the reacting fluid in the main passage;
- and
- an expansion chamber to provide mixing of the feed material and the reacting fluid.
