Moreover, since water is directly sprayed into the metal energy that has become a fake, is the metal energy evaporating due to the evaporation of water? Since about 600"/~ of heat is carried away as I heat, it has the advantage of being able to provide sufficient 'I' conventional cooling, compared to the conventional case of indirect cooling using an air fin cooler etc. There is.

In addition, according to the present invention, a water jet device is installed in the cooling air passage inside the gas turbine and only the water jet is performed. There is also the advantage that cooling can be carried out without increasing pressure loss.

Here, when the gas turbine is started or stopped, the air in the cooling air chamber quickly evaporates the entire amount of water sprayed from the water jet device (2). This water does not evaporate quickly, and the water droplets directly hit the turbine components in the cooling air chamber, rapidly cooling the surrounding parts and causing cracks. Water should not be sprayed unless the temperature is sufficient to quickly evaporate the entire amount.

In addition, when stopping water spraying, if the main valve of the piping system that supplies water to IT is closed, the pressure of the water remaining between the pulp and the water spraying device will drop (7. Water must be prevented from dripping or dripping, as this will cause water to drip down from the spouting device and cause the above-mentioned problems.

In the present invention, water is sprayed using air as the primary source, and the temperature of the air in the cooling air chamber is detected by a detector. especially when stopping the water spray.
Since the supply of pre-trap water is stopped and the supply of nitrogen is stopped after the water after the valve in the piping system has been sprayed, water droplets that have not yet evaporated will not reach the high-temperature turbine parts. Quickly cool down the Jl that has been directly hit or dripped with water.
It has the advantage that cooling can be performed without causing negative effects such as causing cracks.

On the other hand, by cooling the cooling air and lowering its temperature, the entire operating temperature of the gas turbine can be increased without increasing the amount of cooling air.

Here, in the conventional method, by increasing the cooling wall thickness, t'i, the ability to cool the turbine blades increases and the temperature of the gas used can be raised, but as the temperature of the gas used rises, the heat received by the turbine blades increases. As the cooling air increases, the temperature of the cooling air itself also decreases considerably υ, and the temperature k with the turbine blade decreases, so even if the amount of cooling air is increased, the cooling effect cannot be greatly improved. On the other hand, if the temperature of the cooling air is lowered as in the gas turbine of the present invention, the temperature difference between the cooling air and the turbine blade increases, and the cooling effect is greatly improved.

しi・も、冷却効果が同上すれば、冷却空気量を増加す

Also, if the cooling effect is the same as above, there is no need to increase the amount of cooling air.

Furthermore, according to the present invention, since water is sprayed into the cooling air, the volume of the cooling air increases accordingly, which reduces the amount of cooling air output by the compressor and improves the cycle efficiency of the gas turbine. will improve.

Further, according to the present invention, since moisture is added to the cooling air, the specific heat of the cooling air increases, and from this aspect as well, the cooling effect is higher than that of cooling using only the cooling air, and the usage of cooling air is reduced accordingly. Alternatively, the temperature of the upper gas can be increased, improving the cycle efficiency of the cast turbine.

In addition, according to the present invention, since the water is removed in the cooling air passage inside the gas turbine, there is no increase in pressure drop, unlike when the water is first guided outside the gas turbine and cooled with an air fin cooler or the like. Another advantage is that it is possible to achieve a 7° irradiation of the turbine first stage stationary blades, which was not possible with this method.
