Traditionally, in gas combustion turbines, axial or centrifugal air compressors are used, so that the compressed air is continuously discharged, mixed with fuel and continuously stored in the air compressor chamber. It is possible to operate without constantly needing a spark hydrant. However, in axial flow type or centrifugal type air compressors, the air pressure cannot rise rapidly at the start, resulting in poor combustion efficiency. In addition, the rotational speed must always be kept constant, and if the load fluctuates, efficiency will deteriorate.

The pulsating air flows into the combustion chamber 3 through the discharge pipe 6, mixes with fuel from the fuel supply pipe 9, and burns.
Since the ignition plug 19 must be ignited in a well-timed manner in accordance with the pulsation, the structure is complicated and the cost is high.

The combustion chamber 3 is continuously supplied at a constant pressure via the pressure reducing valve 17.
Flashed inside. The combustion of fuel in the combustion chamber 3 is normally performed by the spark plug 19 and is not pulsating. Since the combustion gas becomes a uniform and continuous flowing gas and flows into the expander 1 through the gas pipe 7,
The rotation of the expander 1 is also consistent. In addition, spark plug 1
Reference numeral 9 can also be an ignition burner that is always lit if necessary. Furthermore, the pressure reducing means may be an appropriate throttling mechanism that adjusts the cross-sectional area instead of a pressure reducing valve.

Airfoil type, speed type axial flow type or centrifugal type. These air compressors can only be used within a narrow control range because if the rotational speed changes or the intake air conditions (air volume, inlet air temperature, etc.) change due to usage conditions, they will deviate from their design point and cause surging or choke. ,
Furthermore, there was a drawback that the efficiency decreased significantly when the design point was deviated from, but according to the present invention, since a screw type air compressor is used, the above-mentioned drawback of the prior art is eliminated.
