    摘要： The temperature and flow rate of steam introduced to a gas turbine and a combustor is controlled properly through mixing intermediate-pressure steam and high-pressure steam. Thus, two different requirements, i.e., adjustment of steam temperature and securing of a sufficient steam flow rate, can be satisfied simultaneously. As a result, it becomes possible to simultaneously achieve control of the clearance of the blade ring of the gas turbine by means of steam and cooling of the combustor by means of steam.

    摘要： In the gas turbine combined plant, water fed to an entrance of a high-pressure economizer is guided into an air cooler as a cooling medium of high-temperature air that passes through the air cooler. High-temperature water obtained by heat exchanging with high-temperature air is branched to a passage that joins water drawn from an exit of the high-pressure economizer and a passage that joins a condenser. These passages are provided with regulating valves that regulate the flow rate of the water that passes through these passages, respectively.

    摘要： The gas turbine fuel gas filling apparatus includes a main fuel valve, a fuel valve, an inert gas purge valve, and a pressure detector for detecting a pressure in the fuel line. The main fuel valve is gradually opened, and fixed to a valve opening at a time when a predetermined first pressure condition is established. Pressure is measured after lapse of a predetermined time. The main fuel valve is gradually opened until a second pressure condition is established. Pressure is measured upon a completion of gas-filling. With establishment of a third pressure condition, the inert purge relief valve is closed. With establishment of a fourth pressure condition, the main fuel valve is fully opened.
