するものに関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas turbine used in, for example, a thermal power plant, and more particularly to a gas turbine for suppressing a decrease in gas turbine output due to a rise in atmospheric temperature.

転数が一定であることから常に同一体積であるが、その
質量は、大気温度が低く空気密度が高いときは大きく、
大気温度が高く空気密度の低いときは小さくなる。As is well known, combustion air supplied to a gas turbine is generated from an air compressor directly connected to the combustion air. In this case, the volume of the combustion air is always the same because the rotation speed of the air compressor is constant, but its mass is large when the atmospheric temperature is low and the air density is high,
It decreases when the atmospheric temperature is high and the air density is low.

量と燃焼ガス温度とに比例するが、通常、ガスタービン
は、燃焼ガス温度を一定とするように運転されることか
ら、大気温度が高くなると燃焼ガス量が減少し、ガスタ
ービン出力が減少することになる。On the other hand, the output of the gas turbine is proportional to the amount of combustion gas and the combustion gas temperature. Normally, however, the gas turbine is operated so that the combustion gas temperature is constant, so that the atmospheric temperature is high. If this happens, the amount of combustion gas will decrease and the gas turbine output will decrease.

燃焼用空気の温度を下げることにより、ガスタービン出
力が減少することを抑制するようにしている。Therefore, for a gas turbine used in a high temperature and low humidity area, for example, by installing a dedicated large-scale cooler, the temperature of the combustion air supplied to the gas turbine is lowered to reduce the gas turbine output. It is trying to suppress the decrease of.

空気の温度を下げるために専用の大型クーラーを設置す
ることは、年間を通じて高温な地域では有用であるが、
寒暖の差がある地域では、高温になるわずかな期間にし
かクーラーが使用されないため、設備費に対する利益率
が悪く経済的に不利になるという問題が生じる。By the way, installing a dedicated large-scale cooler for lowering the temperature of the combustion air supplied to the gas turbine is useful in hot regions throughout the year.
In an area where there is a difference in temperature, the cooler is used only for a short period of time when the temperature is high, which causes a problem that the profit ratio against the facility cost is poor and it is economically disadvantageous.

向きであるという問題を有している。As described above, according to the conventional means of installing a large-scale cooler for exclusive use in order to suppress the decrease in gas turbine output due to the rise in atmospheric temperature, the equipment becomes large-scale, so it is cold and warm. There is a problem that it is unsuitable for areas with differences.

Thus, it is an object of the present invention to provide an extremely good air cooling device for gas turbine combustion, which can suppress a decrease in gas turbine output due to an increase in atmospheric temperature.
