Abstract
Abstract An oil burner having two separate, individually fed oil injection systems, one of which injects one or more narrow, axially directed oil streams, and the other of which injects one or more short, wide-angle oil streams. The apparatus is so arranged that the streams injected by the two systems intersect one another to form a composite stream which combusts to form a composite flame.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
148 words
A variable oil fired burner assembly comprising first liquid fuel injection tip means for forming a long narrow liquid fuel jet along a first axis and second liquid fuel injection tip means for forming a short wide liquid fuel stream that intersects said first axis so as to form a composite liquid fuel jet, a tip head for mounting said tip means in relative fixed spaced apart relation, first fuel supply means for controllably supplying liquid fuel to said first tip means, second fuel supply means for controllably supplying liquid fuel to said second tip means, and means for independently controlling the relative rate at which said first and second fuel supply means supply liquid fuel to respective said tip means so that the shape of the composite liquid fuel jet can be controllably continuously varied between a long narrow fuel jet and a wide short fuel jet.
Claim 2
Dependent Claim
148 words
A variable oil fired burner assembly comprising first liquid fuel injection tip means for forming a long narrow liquid fuel jet along a first axis and second liquid fuel injection tip means for forming a short wide liquid fuel stream that intersects said first axis so as to form a composite liquid fuel jet, a tip head for mounting said tip means in relative fixed spaced apart relation, first fuel supply means for controllably supplying liquid fuel to said first tip means, second fuel supply means for controllably supplying liquid fuel to said second tip means, and means for independently controlling the relative rate at which said first and second fuel supply means supply liquid fuel to respective said tip means so that the shape of the composite liquid fuel jet can be controllably continuously varied between a long narrow fuel jet and a wide short fuel jet.
Claim 3
Dependent Claim
78 words
The invention of claim 1 in combination with third liquid fuel injection tip means for forming a short wide liquid fuel stream, said third tip means being in communication with said second fuel supply means, said third tip means being spaced from said first and second tip means, said third tip means being oriented so that the short wide liquid fuel stream produced thereby intersects with the liquid fuel stream that is formed by said first tip means.
Claim 4
Dependent Claim
105 words
The invention of claim 1 in combination with third and fourth fuel tips in communication with said first fuel supply meaNs, said first, third and fourth fuel tips being adapted to form long narrow convergent fuel streams, fifth and sixth fuel tips in communication with said second fuel supply means, said second, fifth and sixth fuel tips being adapted to form short wide fuel streams, all said fuel tips being arranged in a circular pattern, members of a group consisting of said first, third and fourth tips alternating with members of a group consisting of said second, fifth and sixth tips around said circular pattern.
