Abstract
A method and apparatus for burning oil or gas mixed with air to produce a long stable flame in which the fuel is atomized in a chamber by a primary atomizing medium introduced tangentially into the chamber to form a confined stream, secondary air moving parallel to the confined streams mixed with the stream which is then expanded and tertiary air supplied to the stream in a helical swirling path about the stream periphery.
Claims5
A method of burning liquid fuel with air so as to produce a long stable flame comprising:
- atomizing said fuel by swirling;
- mixing said fuel with primary air by introduction under pressure the primary air into a flow of said swirling fuel tangential to the direction of said flow and forming a confined cylindrical stream;
- releasing said confined stream;
- introducing secondary air flowing parallel to said released stream into said confined stream;
- expanding said released stream from a first to a second cross-section larger than said first cross-section during introduction of said secondary air;
- and
- supplying tertiary air to said stream in a helical swirling path about the periphery of said second cross-section and within a transition between said second cross-section and a larger cross-section so that said tertiary air is admixed with the burning mixture over an extended distance to produce a stable flame.
A burner for the combustion of a liquid hydrocarbon fuel with air to produce a long stable flame comprising:
- means for whirling and atomizing said fuel including a cylindrical atomizing chamber having a discharge end, means for whirling said fuel into said chamber as a flow and means defining feed passages for introducing primary air into said chamber tangential to the direction of said flow to form an atomized fuel mixture and produce a confined flow of said atomized fuel mixture;
- a first burner tube disposed about said atomizing chamber, extending in the direction of said flow, and terminating in an open mouth;
- means for supplying secondary air to said burner tube so that the supplied air moves in parallel to said flow about the periphery thereof and is mixed therewith as it exits the discharge end of said chamber and exits through said open mouth;
- a second burner tube disposed about said first tube and extending in the direction of said flow past said open mouth;
- and
- means for supplying tertiary air to said second burner tube so that the supplied air moves in parallel to the flow exiting from said mouth and so that the supplied air flows helically about the periphery of the flow from said open mouth and said tertiary air is admixed to the burning mixture over an extended distance to produce a stable flame.
