ABSTRACT:
A nozzle for use with a rotary kiln of the type used for reducing ore, such as iron ore, to a lower state of oxidation. The nozzle projects in a generally radial direction through the kiln shell to inject fluid into the interior of the rotary kiln. The nozzle comprises a gas passage for admitting a reductant gaseous fluid such as natural gas (methane) or an oxidizing fluid such as air into the kiln at appropriate times in the cycle of rotation of the kiln. The nozzle also includes a central oil tube slidably adjustably mounted in a sleeve which extends to the nozzle tip. The gas passage through the nozzle forms a hollow chamber around the sleeve in which the oil tube is enclosed, whereby the gas passing through the hollow chamber provides a cooling action on the oil tube and on the nozzle tip. The discharge outlet of the oil tube may be located within its enclosing sleeve in spaced relation to the nozzle tip, and in a cooler zone than the nozzle tip, whereby to minimize clogging of the oil tube discharge outlet by carbon deposits or the like. The central oil tube may be slidably moved within its enclosing sleeve to permit cleaning of carbon deposits from the nozzle tip. A quick disconnect coupling at the inlet end of the central oil tube permits disconnection of the oil supply to the oil tube while the kiln is rotating, permitting insertion of a cleaning rod in the oil passage of the central oil tube to "rod out" the central oil tube, the cleaning rod being extendible into cleaning engagement with the nozzle tip. The central oil tube may also be completely removed and replaced with another oil tube while the kiln is rotating.
