Abstract
Abstract A nozzle for finely dispersing a liquid in a gas stream, usually air or steam, has therein a reverberation chamber for producing acoustic energy in the gas stream. The gas then flows through a plurality of tubular passages which are intersected by tubular passages carrying therethrough a liquid to be nebulized, said liquid usually being oil. The nozzle is particularly useful for nebulizing oil in preparation for combustion thereof.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
195 words
An improvement in an acoustic nozzle for nebulizing oil in preparation for combustion thereof, said acoustic nozzle having a central axis and being supplied with a gas through an inner tube and with oil through an annulus defined by said inner tube and an outer tube surrounding said inner tube, wherein said improvement comprises an axial resonant chamber in said nozzle for introducing acoustic enerGy into said gas, said chamber being continuous with said inner tube and supplied with gas therefrom, a plurality of first tubular passages leading from said inner tube adjacent said resonant chamber to the exterior surface of said nozzle for conducting said gas containing acoustic energy to said exterior surface of said nozzle, and a plurality of second tubular passages, each of said second tubular passages having an inner and an outer end, all of said inner ends making connection with said annulus for receiving flowing oil, and each of said outer ends intersecting one of said first tubular passages at a region proximate the exterior surface of said nozzle, thereby serving to bring together gas and oil streams for nebulizing said oil by said acoustic energy in said gas stream.
Claim 2
Dependent Claim
195 words
An improvement in an acoustic nozzle for nebulizing oil in preparation for combustion thereof, said acoustic nozzle having a central axis and being supplied with a gas through an inner tube and with oil through an annulus defined by said inner tube and an outer tube surrounding said inner tube, wherein said improvement comprises an axial resonant chamber in said nozzle for introducing acoustic enerGy into said gas, said chamber being continuous with said inner tube and supplied with gas therefrom, a plurality of first tubular passages leading from said inner tube adjacent said resonant chamber to the exterior surface of said nozzle for conducting said gas containing acoustic energy to said exterior surface of said nozzle, and a plurality of second tubular passages, each of said second tubular passages having an inner and an outer end, all of said inner ends making connection with said annulus for receiving flowing oil, and each of said outer ends intersecting one of said first tubular passages at a region proximate the exterior surface of said nozzle, thereby serving to bring together gas and oil streams for nebulizing said oil by said acoustic energy in said gas stream.
Claim 3
Dependent Claim
18 words
The improvement as defined in claim 1, wherein the exterior surface of said nozzle is frustoconical in shape.
Claim 4
Dependent Claim
31 words
The improvement as defined in claim 2, wherein the outer ends of said tubular passages lie on a circle the plane of which is perpendicular to the axis of said nozzle.
Claim 5
Dependent Claim
30 words
The apparatus as defined in claim 1, wherein a stem is located axially in said resonant chamber in order to increase the efficiency of acoustic energy transfer to said gas.
Claim 6
Dependent Claim
49 words
The apparatus as defined in claim 4 wherein said stem has a flange at its upstream end, said flange being held between said nozzle and the downstream end of said inner tube, said flange having passages therethrough connecting said inner tube with said nozzle for flow of gas therethrough.
Claim 7
Dependent Claim
21 words
The improvement as defined in claim 1, wherein the number of first tubular passages equals the number of second tubular passages.
Claim 8
Dependent Claim
127 words
An acoustic nozzle having a downstream exit end and an upstream inlet end comprising a central passage extending between said inlet and exit ends for receiving gas supplied at said inlet end, a resonant chamber communicating with said central passage and located adjacent said exit end, a plurality of exit passages extending between said central passage and the exterior of said nozzle to deliver gas outwardly of said nozzle at acoustic energies from said central passage, said exit passages communicating with said central passage upstream of the end of said resonant chamber, and a plurality of fuel passages within said nozzle for receiving fuel to be nebulized, said fuel passages having inlet and outlet ends, said outlet ends communicating with said exit passages intermediate the ends thereof.
Claim 9
Dependent Claim
127 words
An acoustic nozzle having a downstream exit end and an upstream inlet end comprising a central passage extending between said inlet and exit ends for receiving gas supplied at said inlet end, a resonant chamber communicating with said central passage and located adjacent said exit end, a plurality of exit passages extending between said central passage and the exterior of said nozzle to deliver gas outwardly of said nozzle at acoustic energies from said central passage, said exit passages communicating with said central passage upstream of the end of said resonant chamber, and a plurality of fuel passages within said nozzle for receiving fuel to be nebulized, said fuel passages having inlet and outlet ends, said outlet ends communicating with said exit passages intermediate the ends thereof.
Claim 10
Dependent Claim
24 words
An acoustic nozzle as claimed in claim 7 wherein said central passage includes a stem positioned centrally thereof and extending into said resonant chamber.
Claim 11
Dependent Claim
32 words
An acoustic nozzle as claimed in claim 8 wherein said stem carries radially extending flanges at the upstream end thereof for segmenting a portion of said central passage intermediate the ends thereof.
