Abstract
A port assembly for delivering fluid through a shell of a horizontal rotating reactor, such as a rotary kiln, is disclosed for purging from the port particulate material which enters port piping when no fluid is passing through the port. The port assembly comprises a cylindrical nozzle disposed in a port pipe, or port sleeve. The nozzle defines a nozzle orifice for discharging fluid into the reactor. A base member having a sloping surface is provided adjacent the nozzle with the sloping surface and nozzle cooperating to define a fluid distribution cavity with a thickness constantly varying from its circumference toward its center. The base member is sized as to define a fluid supply passage with facing surfaces of the port sleeve. Rest tabs along the circumference of the base member separate the base member from the nozzle while permitting communication between the fluid supply passage and fluid distribution cavity. A sealing ring is provided between the nozzle and base member and engages the port sleeve in sealing contact. Particulate material within the sleeve accumulates within the fluid supply passage and rests against the sealing ring as the port rotates with the reactor. Flui…
