Gas distributor nozzles

摘要

Systems and methods for injecting gas into a fluidized bed of particles are provided. The system can include a gas distribution system. The gas distribution system can include a header having a flow passage and a nozzle body coupled to the header. The nozzle body can have an inlet end in fluid communication with the flow passage and an outlet end positioned outside of the header. The nozzle body can have a longitudinal axis that is substantially perpendicular to a direction of flow through the flow passage. The nozzle body can have an orifice positioned between the inlet end and the outlet end.

1. A gas distribution system, comprising:
a header having a flow passage contained therein; and at least one nozzle body partially disposed within the flow passage, wherein:
the at least one nozzle body has a wall defining an inlet end positioned within the flow passage and in fluid communication with the flow passage and an outlet end positioned outside of the header;the at least one nozzle body has a longitudinal axis that is substantially perpendicular to a direction of flow through the flow passage; andthe at least one nozzle body has an orifice formed radially through the wall and positioned between the inlet end and the outlet end to regulate fluid flow from the flow passage into the at least one nozzle body,wherein the at least one nozzle body has an upstream side facing the direction of flow and a downstream side not facing the direction of flow and wherein the orifice positioned between the inlet end and the outlet end is positioned on the downstream side of the at least one nozzle body.
