Abstract
A fuel combustion apparatus 2 according to the present invention includes: a combustion cylinder 4; a fuel feed unit 6 that introduces a swirling flow of an air-fuel mixture into the combustion cylinder; an ignition unit 10 including an igniter 32 located in the combustion cylinder 4; an ion detection unit 12 including a detector 40 located in the combustion cylinder 4; and a control unit 14 that adjusts a mixing ratio of the fuel based on a detection result obtained by the ion detection unit 12. Preferably, the fuel is ammonia. Preferably, the detector 40 is located in the vicinity of the igniter 32.
Claims18
A combustion apparatus that combusts a fuel, the combustion apparatus comprising:
- a combustion cylinder;
- a fuel feed unit that introduces a swirling flow of an air-fuel mixture into the combustion cylinder;
- an ignition unit including an igniter located in the combustion cylinder;
- a plurality of ion detection units each of which includes a detector located in the combustion cylinder;
- and
- a control unit that adjusts a mixing ratio of the air-fuel mixture based on a detection result obtained by the ion detection unit,
- wherein the combustion cylinder includes a tubular barrel and a bottom cover is mounted on a bottom of the tubular barrel, and
- at least first one detector extends from the bottom cover toward an interior of the combustion cylinder, and at least second one detector extends from the tubular barrel toward the interior of the combustion cylinder.
A fuel combustion method comprising:
- a combustion step of combusting a fuel continuously, wherein
- the combustion step includes:
- introducing a swirling flow of an air-fuel mixture into a combustion cylinder;
- igniting the introduced air-fuel mixture;
- detecting ions generated by the combustion of the fuel;
- and
- adjusting a mixing ratio of the air-fuel mixture based on an ion detection result,
- wherein the fuel combustion method further comprises the step of measuring a correlation between a parameter indicative of a combustion state of the air-fuel mixture and the ion detection result and defining a reference range for the ion detection result before the combustion step, and
- wherein a mixing ratio of the air-fuel mixture is adjusted to allow the ion detection result to fall within the reference range.
