ABSTRACT:
It is an object of the invention to provide for a coal in oil mixture a combustor or burner system in which the ash resulting from burning the mixture is of submicron particle size.
The burner system comprises, as shown in FIGS. 1 and 2, a burner section (11), a flame exit nozzle (12), a fuel nozzle section (13) and an air tube (14) by which preheated air is directed into burner section (11). Regulated air pressure is delivered to a fuel nozzle (34) in nozzle section (13) through a line (9). Means (8),(16), and (17),(29),(6),(30) and (31) are provided for directing a mixture of coal particles and oil from a drum (15) to a nozzle (34) of FIG. 2 at a desired rate and pressure while a means (19) returns excess fuel to the fuel drum (15). Means (25) is provided for keeping the coal particles uniformly distributed in the coal in oil mixture in fuel drum (15). Means (29), (30), and (31) provide for stable fuel pressure supply from fuel pump (8) to fuel nozzle (34).
A chamber is provided in the nozzle body (35), as shown in FIG. 3, and nozzle (34) is threaded into the nozzle body (35) inwardly of an end wall (36). Fuel flows from chamber (37) through axial passageways (45) and then radially inwardly through fuel passageways (44). The fuel enters passageway (43) and is atomized by regulated air pressure passing therethrough and exiting at the nozzle orifice.
