摘要： PROBLEM TO BE SOLVED: To stably fix a leveling block on the floor surface by adjusting the block to a desired height by pushing in a jacking bolt from above a jacking bolt hole and rotating the same, thereby adjusting the height of a base part. SOLUTION: Jacking bolt screw holes 27 are worked in four corner parts of a base part 24 of a leveling block 20. Subsequently, four jacking bolts 28 are passed through the jacking bolt screw holes 27, and further lock nuts 29 are passed to be erected in desired installation places of the floor surface B. Then, further jacking bolts 28 are pushed in from above the jacking bolt screw holes 27 and rotated, thereby adjusting the height of the base part 24 to the desired installation places. In adjustment, it is preferable to use a height measuring device 35 and a scale 36 fitted to the upper surface of the leveling block 20. After the height adjusting the lock nut 29 is fastened to the leveling block 20 side to lock the height relationship between the jacking bolt 28 and the leveling block 20.

摘要： PROBLEM TO BE SOLVED: To reduce the thermal stress generated at high/intermediate-pressure sections and reduce the bore stress at the portion of a low-pressure section where high centrifugal force is applied by setting the center holes of the high- temperature high-pressure section or/and intermediate-pressure section of a rotor and the center hole of the low-pressure section applied with the high centrifugal force different in diameter in a high (intermediate)/low-pressure integrated steam turbine rotor. SOLUTION: A center hole ϕd1 slightly larger than the center hole ϕd2, of a low-pressure section 4 is provided on a high-temperature high-pressure section 2 and an intermediate-pressure section 3 in a high (intermediate)/low- pressure integrated turbine rotor. The relatively large center hole ϕd1 is formed on the high-temperature high-pressure section 2 and the intermediate-pressure section 3, the thickness of the rotor at this portion is made small on the contrary, and the thermal stress generated at the time of excessive changes, e.g. at the time of a start and a stop, at this portion is reduced in the combined cycle requiring a quick start, for example. The time to reach the target load is shortened, an excellent operating characteristic is obtained, and the life of a steam turbine can be prolonged.

摘要： PURPOSE:To improve the extent of efficiency in a steam turbine as well as to promote the compactification of a building by setting up a high pressure part or high, medium pressure part of the steam turbine in the first shaft and a low pressure steam turbine in the second shaft downward, respectively. CONSTITUTION:A gas turbine 1, a compressor 2, and a high, medium pressure steam turbine 3 plus a generator 5 are all connected to an A shaft through a rigid coupling. Likewise, those of gas turbine 1, compressor 2, low pressure steam turbine 4 and generator 5 are all connected to a B shaft through the rigid coupling. As for a steam cycle, exhaust steam out of the low pressure turbine 4 is condensed by a condenser 6, and subjected to heat exchanging by each exhaust heat recovery boiler 7 utilizing exhaust heat of the gas turbine 1 of each shaft, it turns to high pressure and high temperature steam. Each steam to be produced out of these two boilers 7 is converged into one and fed to the high-medium pressure turbine 3. Exhaust steam out of a medium pressure part of this high-medium pressure turbine 3 is fed into the low pressure turbine 4 by a cylinder connecting pipe 8. Thus, the extent of efficiency in the steam turbine is improvable.
