Abstract
The present specification generally relates to improvements to combustors such as burners and engines. In one aspect, the specification presents an acoustically enhanced ejector system which can be used as part of an intake system for a combustor. In another aspect, the specification teaches the use of a combustor combustion chamber as an oscillator to magnify a harmonic frequency of a pulsating frequency of the combustor. In still other aspects, the specification presents a combustion chamber having an inlet with a plurality of tangentially spaced apertures, and an in-line intake system connected to the apertures.
Claims13
A combustor comprising:
- a resonator having a fundamental resonance frequency which corresponds to a pulsating frequency of the combustor when operating in a pulse mode, the resonator further having:
- an oscillator for use as a combustion chamber, having a fundamental resonance frequency which is an odd harmonic of the pulsating frequency, and having
- an inlet at an acoustic center thereof, the oscillator defining one end of the resonator;
- an exhaust pipe extending from the oscillator and having an outlet at the opposite end of the resonator;
- and
- an intake system connected to the inlet of the oscillator to feed the combustion chamber with fuel and air.
