Description
The present invention relates to a gas turbine test apparatus and a gas turbine test method using the gas turbine test apparatus. More particularly, the present invention relates to a gas turbine test apparatus, And a gas turbine test method using the gas turbine test apparatus.
Gas Turbine means a rotary power engine that extracts energy from the flow of combustion gas. Such a gas turbine is composed of a compressor, a combustion chamber, a turbine, and the like. In the compressor, air is compressed. In the combustion chamber, compressed air is mixed with the fuel and burned. The turbine is driven by the force generated as the fuel is burned in the above combustion chamber. The energy generated by the above process is used to drive an aircraft, a train, a ship, a generator, a tank, and the like.
In recent years, gas turbine-based power generation facilities have been increasing due to pollution problems caused by rapid industrial development and global warming. In order to produce high-efficiency large-capacity gas turbines, various countries have competitively studied and developed new types of gas turbines . As of 2009, the maintenance market for industrial gas turbines is about 40% of the product market and is expected to grow at an annual average of 3.7% through 2018.
Meanwhile, the blade, which is a core component of the gas turbine, is in direct contact with high-temperature and high-pressure gas at the time of starting, and is exposed to a harsh environment such as rotating at high speed, thereby significantly affecting the performance and lifetime of the gas turbine. Therefore, the test of the gas turbine can be said to be the evaluation of various performances of the above-mentioned blades.
For the accuracy of the test, the performance should be tested using an actual turbine installed in a large unit. However, as described above, since the gas turbine is used as a power means for a large apparatus such as an aircraft, a train, and a generator, when the actual turbine is used as it is, the capacity of the compressor must be equal to the capacity actually used. It should be supplied in the same amount as the actual fuel amount. Therefore, when the actual turbine is used as it is, there is a problem that the equipment for constructing the test apparatus and the energy consumed in the test process are enormous.
In order to reduce the energy consumed in the test process, conventionally, the size of the turbine was reduced and the test was performed. However, in the case of the conventional test described above, since the size of the blades installed on the disk is also reduced in proportion to the reduction of the turbine size, the results for the blade of actual size can not be accurately obtained, do.

According to the present invention, the reliability of the test can be improved because the actual turbine blades are used while reducing power consumption and facility installation cost during the test.
In addition, since the cross-sectional area of the flow path through which the gas flows is reduced by the disk portion provided with the diameter smaller than the diameter of the disk, the amount of gas supplied to the flow path is reduced so that the consumption power required for the test and the installation cost are significantly reduced .
In addition, the use of the blades of the threaded shape is used as it is, and the reliability of the test is improved.
Further, the gas turbine test can be continuously carried out by cooling the turbine section by using the second compressed section that supplies the compressed gas to the turbine section.
