The air passing through the combustion chamber passage 501 produces directionality and velocity by the Venturi effect including the Coanda effect by the Coanda surface and Bernoulli's theorem, (601) and discharged to the outside through the flue (602).

Since the air passing through the combustion chamber passage 501 stuck to the shape 502 of the Venturi tube structure of the combustion chamber passage 501 and the Coanda Surface 503, the Bernoulli's theorem The air passing through the combustion chamber passage 501 forms a relatively lower air pressure than the air in the combustion chamber 408 and the air in the combustion chamber 408 is discharged to the combustion chamber passage 501 ) Direction and increases the moving speed.
