摘要： Extremely cold (e.g., −20° C.) air A is heated by a heat exchanger 30, which is supplied with steam S via a control valve 32, and heated air A′ is taken into a gas turbine 10. The valve opening degree of the control valve 32 is feedback-controlled so that the deviation between the measured temperature t1 and the target temperature TO of the heated air A′ is eliminated. Further, when the number of revolutions, N, of the gas turbine 10 increases, or when an IGV opening degree OP increases, the valve opening degree of the control valve 32 is feedforward-controlled in accordance with the increase in the number N of revolutions or the increase in the IGV opening degree OP. By so doing, the temperature of air A′ can be maintained at a temperature enabling stable combustion without delay in control, and intake air can be heated without delay in control, even at the start of the gas turbine or during change in the opening degree of an inlet guide vane.

摘要： A gas turbine control apparatus, etc. are provided by which combustion fluctuation, even if arising in plural frequency bands, can be effectively suppressed. If the combustion fluctuation arises in plural frequency bands, corresponding to a predetermined priority order, adjustment is done so that the combustion fluctuation of the frequency band of a high priority order is suppressed. If the gas turbine state changes after the adjustment, this is reflected on a data base 30. If no sufficient data is stored yet in the data base 30 for any the reason, such as immediately after installation of the gas turbine, correction is made using data of countermeasures based on data of another same type gas turbine contained in a basic data base 31 and data of countermeasures based on experiences of skilled adjusting operators contained in a knowledge data base 32. Also, in a stabilized operation, operation condition may be varied so that an optimal operation condition is automatically searched.

摘要： A building structure including a beam of steel or rod reinforced concrete which is sheathed in a U-shaped cross section steel shell, a concrete column which is encased in a steel tube, diagonal bracings and connecting members thereof. The topside of the U-shaped steel shell is open to allow concrete to be filled therethrough. Steel rods are placed in the shell and a steel panel connecting member secures the opposed sidewalls of the shell. Steel bars extend from a floor slab into the beam shell through the aforesaid open topside, thereby rendering the beam integral with the slab. Frame-like steel members for confining reinforcing bars and/or shear connectors are disposed in the inside of the beam shell. A steel sleeve is also provided in the beam shell for defining a space for disposition of equipment. In addition, an opening is provided in the bottom wall of the beam shell so as to allow steel rods to extend from the wall into the beam shell, thereby rendering the beam integral with the wall. A column is coupled to the beam by means of ring stiffeners or gusset plates. Diagonal bracings are positioned in symmetric relation to the frame member of the beam or column, and the diagonal bracings are fastened to the frame member of the beam or column by means of long bolts extending through the frame member thereof. The tip portions of diagonal bracings are provided with anchor members which are embedded in the concrete contained in the beam shell.
