PURPOSE:To permit to compact a whole device and improve thermal efficiency by a method wherein a combustion chamber is formed in the inside of an inner cylinder, and a tail pipe unit is formed so as to flow exhaust gas of pulse oscillating condition between an outer cylinder and an inner cylinder. CONSTITUTION:In a pulse combustion device 22, a double pipe 25 is provided with an inner cylinder 23 which one side end of it is closed and other side end is open, and an outer cylinder 24 provided on the outside of the inner cylin der 23. A mixture supplying pipe 29 and an igniter (ignition device) 30 are inserted respectively in the closing end of the inner cylinder 23 and a combustion chamber 34 is formed in the inside of the inner cylinder 23. The tail pipe unit 37 is formed so as to flow the exhaust combustion gas of the pulse oscillating condition by annular space R between the outer cylinder 24 and the inner cylin der 23, and the whole constitution of the pulse combustion devise 22 may be simplified. |
