Abstract:
1. An oil burner assembly, comprising: a) an oil distribution nozzle; b) a manifold i) constructed of a unitary body of thermally transmissive material and ii) having first and second continuous passageways, wherein each of said first and second passageways terminates at separate inlet and outlet ports, wherein said oil distribution nozzle is coupled to the outlet port of said first passageway; c) a source of oil coupled to the inlet port to said first passageway such that the oil flows through said first passageway and is discharged from said nozzle; d) a source of heated liquid coupled to the inlet and outlet ports of said second passageway to flow through said second passageway such that the heated liquid flow heats the manifold and transfers heat to oil in the first passageway to elevate the temperature of oil flowing in said first passage way as the oil is discharged from the nozzle; and e) an igniter mounted to said manifold and aligned to said nozzle to ignite the heated oil discharges from said nozzle; and wherein the outlet port of the first passageway includes first and second cavities, wherein said second cavity is coaxially aligned upstream of said first cavity, wherein an oil distribution portion of said nozzle mounts in said first cavity, and wherein the manifold includes a third passageway that terminates in said second cavity.
