FUEL SPRAY COMBUSTION DEVICE

摘要

A domestic or industrial fuel spray combustion device comprises: a cylinder-shaped swirl chamber into which air streams are introduced; a fuel injection atomizer for spraying fuel to the swirl chamber; an ignition plug; a first combustion cylinder connected through a choke to the swirl chamber, the first combustion cylinder being coaxial with the swirl chamber; and being larger than an equal to the swirl chamber in diameter; and a second combustion cylinder conected through a choke to the first combustion cylinder, the second combustion cylinder being coaxial with the first combustion chamber and being equal to or smaller than the first combustion cylinder in diameter. This structure provides a compact combustion device which enables stable combustion even with a small amount of fuel.
