Morrow, R S; Reschly, D C

A fuel distribution system is described for distributing fuel into a furnace, comprising: (a) at least one oscillating damper, said oscillating damper having an air supply duct, a pivotal valve member mounted in said air supply duct for oscillation about an axis, and control means attached to said valve member for controlling the oscillation of said valve member, thereby controllably adjusting the flow of air through said air supply duct and to effect an adjustable throttling of the air flow there through; (b) at least one air-swept distributor, said air-swept distributor having a fuel inlet duct and a pivotable air chamber, a trajectory plate attached to said air chamber for pivotal movement therewith with respect to said fuel inlet duct for controlling the distribution of fuel into the furnace, means for directing air across said trajectory plate to controllably blow the fuel across the plate and thereby further provide a controllable distribution of fuel into the furnace, said pivotable air chamber having an air inlet opening and at least one air outlet opening for directing air across said trajectory plate; (c) means for communicating air from said oscillating damper to said air-swept distributor; and (d) adjustment means actuable to pivot said air chamber and said trajectory plate in order to change the pivoted orientation thereof and thereby adjustably vary the distribution of fuel into the furnace, said adjustment means being actuable in conjunction with said oscillation of said oscillating damper by said control means.
