Abstract
A coal nozzle apparatus which includes a generally cylindrical main body and a generally cylindrical tip section disposed in generally coaxial relationship with the main body. The apparatus includes apparatus for mounting the tip section in relation to the body section, including two coaxial pins which, each have an axial portion cooperating with the main body and another axial portion connected to the tip section; each of the pins has a head, each of which is disposed proximate to the geometric center line of the body portion. Each of the pins has an axis that is generally coincident with a diameter of the main body. In some forms, the head of each pin is generally cylindrical in shape and the apparatus for mounting includes respective counterbores dimensioned and configured for cooperation therewith. The apparatus for pivoting may include a generally cylindrical nozzle front that is fixed to the main body and has an inner face, with the tip section disposed in side abutting relation to the nozzle front. The counterbores may be disposed in the nozzle front and the heads may be disposed in substantially flush relationship to the inner face of the nozzle front, and the pins may be welded to the nozzle front.
