Abstract
An apparatus and process using a pulse combustor to atomize a liquid or slurry is provided. The apparatus includes a pulse combustor for generating a stream of atomization fluid and an oscillating flow field and introduction apparatus for introducing to the influence of the oscillating stream of atomization fluid a liquid or slurry to be atomized.
Claims17
A liquid or slurry atomization apparatus comprising:
- a) a pulse combustor for generating an oscillating flow field of atomization fluid, said pulse combustor including means for introduction of fuel thereto, valve means for introduction of air thereto, a combustion chamber in communication with said valve means, and a resonance tube in communication with said combustion chamber wherein said resonance tube and said combustion chamber communicate with each other at a juncture;
- and
- b) means for introducing a liquid or slurry to be atomized to said pulse combustor, said introduction means being located adjacent said juncture of said combustion chamber and said resonance tube so that said liquid or slurry may be atomized.
A fuel atomizer apparatus comprising:
- a) a pulse combustor capable of producing a pulsating flow of atomization fluid and an acoustic wave at a frequency in a range of from about 20 to about 1500 Hz, said pulse combustor comprising a combustion chamber, means for introducing fuel and air to said combustion chamber, and at least one resonance tube in communication with said combustion chamber;
- and
- b) means for introducing a fuel to be atomized to said pulse combustor adjacent the location where said resonance tube and said combustion chamber communicate so that said fuel to be atomized may come under the influence of said pulsating flow of atomization fluid to produce atomized fuel.
An apparatus for creating and utilizing an atomized fuel comprising:
- a) a pulse combustor for producing an oscillating stream of atomization fluid, said pulse combustor having a combustion chamber, valve means in communication with said combustion chamber for admitting air to said combustion chamber, a first fuel introduction means for admitting fuel to said pulse combustor for the firing of same, and a resonance tube in communication with said combustion chamber;
- b) means for admitting an additional fuel to said pulse combustor at a location near the point where said resonance tube and said combustion chamber communicate so that said fuel may be atomized by said stream of atomization fluid under the influence of said oscillating flow field;
- and
- c) means in communication with said resonance tube for utilizing said atomized fuel produced by said pulse combustor.
A method for atomizing liquids or slurries comprising:
- a) pulse combusting a fuel in a combustion chamber;
- b) generating combustion-induced oscillations to produce a stream of atomization fluid;
- and
- c) introducing a liquid or slurry to be atomized to the influence of said stream of atomization fluid immediately after combusting said fuel so that an atomized liquid or slurry is produced under the influence of said oscillated stream.
A method for atomizing a fuel with a pulse combustor having a combustion chamber, means to introduce air and fuel into said combustion chamber, and at least one resonance tube in abutting relationship with said combustion chamber comprising the steps of:
- abutting relationship with said combustion chamber comprising the steps of:
- a) supplying a fuel to said combustion chamber;
- b) supplying air on demand to said combustion chamber;
- c) pulse combusting said air and fuel mixture supplied to said combustion chamber to produce an oscillating flow field of atomization fluid exiting from said combustion chamber and entering into said resonance tube;
- d) introducing a fuel to be atomized to said field of atomization fluid adjacent a location where said combustion chamber and said resonance tube abut so that said fuel is atomized by said atomization fluid under the influence of said oscillating flow field to produce an atomized fuel;
- and
- e) providing said atomized fuel for further application.
