摘要： An object of the present invention is to provide a gas turbine control device which is capable of performing correction on the basis of a fuel composition of fuel gas to be supplied to a gas turbine, and is capable of changing an amount of correction in response to variation with time of the gas turbine. To attain this, a frequency analyzing unit 25 performs a frequency analysis of combustion oscillation of a combustor and splits a result of the analysis into respective frequency bands. Then, a state grasping unit 22 checks an operating state of the gas turbine on the basis of the result of the analysis of the combustion oscillation and process value of the gas turbine, and corrects the checked operating state on the basis of a fuel composition or a heat capacity of fuel gas measured by a fuel characteristic measuring unit 200. A countermeasure determining unit 23 conducts a countermeasure for controlling an operating action of the gas turbine on the basis of the operating state thus checked.

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 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.

摘要： A gas turbine has a plurality of combustors in a toroidal arrangement to provide combustion gases to turbine blades, thereby rotating the turbine body. Thermocouples, the number of which is the same as or greater than the number of the combustors, are arranged toroidally at the outlets of the turbine blades and measure the temperatures of the combustion gases at the respective outlets. During the operation of the gas turbine, if an abnormality, such as misfire or fuel injection nozzle obstruction, occurs in one or more of the combustors, the resulting change in gas temperature triggers a signal to stop, and thereby protect the gas turbine. Based on the measured values of the blade pass temperatures of the thermocouples and set threshold temperatures, a fuel supply system may be caused to gradually decrease the fuel supplied to the combustors to bring the gas turbine body to an automatic stop, or it may be cut off instantaneously, thus immediately stopping the gas turbine.
摘要翻译：燃气轮机具有环形布置的多个燃烧器，以向涡轮机叶片提供燃烧气体，从而使涡轮机体旋转。其数量等于或大于燃烧器的数量的热电偶在涡轮机叶片的出口处环形地布置，并且测量各个出口处的燃烧气体的温度。在燃气轮机的运转中，如果在一个或多个燃烧器中发生诸如失火或燃料喷射喷嘴堵塞的异常，则由此导致气体温度的变化触发信号停止，从而保护燃气轮机。基于热电偶的叶片通过温度的测量值和设定的阈值温度，可以引起燃料供应系统逐渐减少供应到燃烧器的燃料以使燃气轮机主体自动停止，或者可以切断从而立即停止燃气轮机。
