A gas turbine is an internal combustion engine that uses combustion gas of a few thousand and several hundred degrees as a working fluid, and is cooled by air in order to increase the reliability of the materials used. Most of the air pressurized at atmospheric pressure by the compressor (1) is introduced into the combustor (2) and used as combustion air for fuel. And
Due to the exothermic reaction of the fuel, combustion gas of a thousand and a hundred degrees is produced. Therefore, the material forming the combustor (2) may be heated to the same temperature as the gas temperature and melted as it is. Therefore, the outer surface of the combustor (2) is cooled by a part of the air compressed by the compressor (1) to lower the temperature of the combustor to prevent melting and to ensure reliability. In FIG. 3, (3) is a gas turbine, and (1
9) is a generator.

なってきている。As the combustion temperature of a gas turbine rises, the proportion of compressor compressed air used for combustion increases, while the combustor, moving / stator vanes, and turbine among the components of the gas turbine. Since the number of disks and other parts that require cooling is increasing, it is indispensable to supply cooling media (for example, water, steam, air, etc.) from the outside, because it is not possible to cover the cooling air simply by extracting air from the compressor. It has become to.

すかが重要な問題になる。By the way, recent gas turbines are often used as a part of components of a combined plant in which a steam cycle is combined, and in such a case, steam can be supplied as a cooling medium from the steam cycle. . In other words, it takes steam from the steam cycle and uses it as steam to cool the combustor, etc., but considering the internal pressure of the combustor and the high temperature of the steam that is heated by itself by cooling the combustor, An important issue is where to return the steam to the steam cycle.

ある。In the present embodiment, the steam generated in the medium pressure drum (12) which constitutes the reheat steam cycle of the combined plant is used as the steam for cooling the gas turbine combustor (2). That is, the internal pressure of the combustor (2) is 1
6 to 17 ata, a pressure level with a moderate pressure difference is required, the pressure is somewhat higher than the high pressure exhaust, and the temperature is conversely quite low.
5ata) is extracted for cooling the combustor (2). The combustor (2) is then heated so that the steam is heated to approximately the reheat steam temperature of the steam cycle.
After being cooled, it is returned to the reheated steam system, mixed with the reheated steam coming from the reheater (6) of the exhaust gas boiler (4), and introduced into the inlet of the intermediate pressure steam turbine (17). It is used as part of the energy to drive the turbine (17) and also the low pressure steam turbine (18). This is because the purpose is to increase the output by recovering the steam in the steam turbine, so that the injection of steam at the inlet of the intermediate pressure turbine (17) can provide a larger output than the injection at the intermediate stage. is there.

る。As described above, in this embodiment, the combustor (2) is used.
Since the steam of the medium-pressure drum (12) is used as a cooling medium for the above, it is possible to supply the steam having a temperature lower than that of the other extraction source satisfying the pressure condition (equal to or higher than the internal pressure of the combustor (2)) as the cooling steam. A high cooling effect can be obtained. If the cooling steam is taken from the outlet exhaust of the high-pressure steam turbine (16), depending on the pressure loss of the cooling steam system, it may be necessary to return it to the intermediate stage instead of the inlet of the intermediate-pressure turbine (17). Due to the temperature difference between and, the temperature of the heated steam after cooling the combustor is restricted to be low. However, in this embodiment, the medium pressure drum (1

A pressure regulating valve (21) is provided in the steam line leading to the outlet medium pressure superheater (9). Therefore, even if the pressure loss of the cooling steam system for cooling the gas turbine combustor (2) is large and it is difficult to obtain a sufficient pressure difference, the pressure adjusting valve (21) is adjusted to adjust the intermediate pressure drum (12).
It is possible to secure the necessary differential pressure by increasing the pressure inside the vessel.

Steam well above the pressure can be bled. In addition, it is possible to obtain a cooling system that minimizes energy loss.

Since it can be ensured, the high temperature of the gas turbine required for high efficiency of the combined cycle plant can be easily achieved. Further, an efficient cooling effect can be obtained with a small amount of cooling steam, and the energy loss can be reduced by adjusting the pressure corresponding to the system pressure loss to reduce the throttling loss.
