MODULAR COAL NOZZLE ASSEMBLY FOR VAPOR GENERATION APPARATUS

摘要

A coal nozzle apparatus (10) which includes a generally cylindrical main body (12) having an inlet and an outlet (14) and a generally cylindrical tip section (20) disposed in generally coaxial relationship with the main body (12). The apparatus (10) also includes apparatus (18) for mounting the tip section (20) in relation to the body section (12) to allow movement of the tip section (20) about an axis that is generally coincident with a diameter of the main body section (12). The apparatus for mounting includes two coaxial pins (18), the pins (18) each have an axial portion cooperating with the main body (12) and another axial portion connected to the tip section (20), each of the pins (18) has a head (18a), each of the heads (18a) is disposed proximate to the geometric center line of the body portion (12). Each of the pins (18) has an axis that is generally coincident with a diameter of the main body (12). In some forms of the invention the head (18a) of each pin (18) is generally cylindrical in shape and the apparatus for mounting includes respective counterbores (14a) dimensioned and configured for cooperation with respective heads (18a) of the pins (18). The apparatus for pivoting may include a generally cylindrical nozzle front (14) that is fixed to the main body (12) and has an inner face. The tip section (20) may be disposed in side abutting relation to the nozzle front (14). The counterbores (14a) may be disposed in the nozzle front (14) and the heads (18a) may be disposed in substantially flush relationship to the inner face of the generally cylindrical nozzle front (14) and the pins (18) may be welded to the nozzle front (14).
