Tilt nozzle for coal-fired burner

摘要

An improved end housing for nozzle assemblies used to project a stream of particulate coal into a burner housing. The improvement includes the addition of vertically-oriented, spaced parallel aiming plates. A four nozzle burner assembly has two sets of diagonally opposite nozzles in which all nozzles are aimed directly at the fireball center.

主权项

1. A coal-fired burner nozzle housing of the type which can be mounted to direct an emergingly unignited stream of particulate coal in a predetermined direction and comprising an open entry side and an open exit side, and a plurality of horizontal splitter plates mounted in spaced parallel relationship within said housing to divide a stream of particulate coal flowing from the entry side to the exit side wherein the improvement comprises:
a plurality of aiming plates mounted on the splitter plates in parallel spaced relationship to one another and in substantially orthogonal relationship to said splitter plates said aiming plates being oriented so that the flow of particulate coal coming from said nozzle is at an angle to said aiming direction.
