The heavy firing fuel nozzle has a fuel gas injection port having an extremely large area in order to stably burn a flame-retardant fuel gas having a low calorific value on the gas injection side. In a multi-can type having such a fuel nozzle, that is, in an oil-fired operation of a gas turbine having a plurality of combustion tubes, an imbalance of combustion is likely to occur between the combustors even under a low load condition. In the worst case, a high-temperature gas circulation flow occurs from the high-pressure combustor to the low-pressure combustor through the large-area fuel gas injection port and the fuel supply piping. Has a tendency to burn out the fuel nozzle and the pipe communicating with the nozzle.

In the figure, 1 is a compressor for obtaining air for combustion and cooling, and high-pressure air 2 compressed to 10 to 15 atm by the compressor 1 guides its flow into a combustor 3 as shown by an arrow. Get burned. A fuel nozzle 4 is attached to the head of the combustion can 3 (on the left side in the drawing). The fuel nozzle 4 includes oil fuel 5a used from ignition of the gas turbine, that is, starting up to about 25% load, and 25 to 100
The low-calorie gas 5b used up to the% load is supplied.
Further, the atomizing air 5 for further atomizing the oil fuel 5a
c is also supplied.

A starting nozzle 11, that is, a flow passage 6 through which the oil fuel 5a flows and a nozzle injection port 6a are formed in the central portion of the axis, and the air 5 for spraying the oil fuel is formed around the flow passage 6.
An air passage 7 through which c flows is formed.

This flow passage is located at different positions in the radial direction and the circumference, as is clear from FIG. The two nozzles 8a and 8b are alternately arranged in the direction.

いる。The flow passage 8 through which the low-calorie gas flows is provided with a purge gas injection device 10 for injecting purge gas into the flow passage. The purge gas ejection device includes a through hole 10a penetrating the wall surface of the flow passage 8, a purge gas flow rate control device 10b, and a purge gas tank 10c.

パージガスとしては空気または窒素が用いられる。The purge gas injection device 10 operates when the combustor is in an oil-fired state, and prevents burnout of the nozzles and pipes. That is, the purge gas 5b is generated due to the internal pressure difference between the combustors due to the manufacturing tolerance of the combustor,
Fuel gas passage 8, Fuel gas branch pipe 20 to each fuel nozzle
(Refer to FIG. 2), it functions to prevent back flow of high temperature gas in the combustor to the fuel gas passage of the fuel nozzle of the other combustor, which is communicated via the fuel gas supply manifold, and burnout of the fuel gas system.
Air or nitrogen is used as the purge gas.
【００１３】尚前述したパージガス噴出孔となる貫通孔
１０ａを次のように形成するとさらに有効である。Further, it is more effective to form the through hole 10a serving as the above-mentioned purge gas ejection hole as follows.

It is provided so as to be inclined in the fuel gas flow direction.

防止することができるのである。With this material, the effect is exhibited particularly with a small amount of purge gas, and the oil-fired combustion flame is not adversely affected. That is, depending on the model, a large differential pressure between the combustors occurs. In that case, the purge gas should be increased. However, the increase in the purge gas blows off the combustion flame and causes misfire. However, in this case, the purge gas acts in the direction of sucking out the gas in the pipe due to the ejector effect, that is, it acts so as to face the inflow direction of the high temperature gas, so even with a small amount of purge gas, a large differential pressure between the combustors can be obtained. Even if there is, it is possible to sufficiently prevent the backflow of high-temperature gas.

In this case, three purge gas ejection holes are arranged side by side so as to form an air curtain with respect to the fuel gas flow passage 8a. Of course, the number is not limited to three, and it is advantageous that a large number of curtains are formed because a dense curtain is formed.
【００１７】このように形成するとこのエアーカーテン

By doing so, the ejector effect described above is improved, and even if there is a large differential pressure, the intrusion of high temperature gas can be prevented. In this case, it may be effective to provide the throttle portion slightly upstream of the purge gas ejection portion.

Even if an internal pressure difference occurs, this purge gas prevents hot gas from entering the nozzle,
Therefore, it is possible to obtain this kind of combustion device in which the nozzle and the pipe are not burned by the high temperature gas.
