摘要： A combustion control device for a gas turbine is capable of controlling fuel ratios such as a pilot ratio and controlling an aperture of a combustor bypass valve in response to a combustion gas temperature at an inlet of the gas turbine in accordance with the original concept by computing a combustion load command value which is proportional to the combustion gas temperature. The combustion control device is configured to calculate a 700° C. MW value and a 1500° C. MW value based on an inlet guide vane aperture, an intake-air temperature, and an atmospheric pressure ratio, then to calculate the combustion load command value to render the combustion gas temperature at the inlet of the gas turbine dimensionless by direct interpolation based on these values and an actual measurement value of a power generator output, and to control apertures of a pilot fuel flow rate control valve, a top hat fuel flow rate control valve, and a main fuel flow rate control valve based on ratios of fuel gas to be determined based on this combustion load command value, and thereby to control fuel supplies to a pilot nozzle, a top hat nozzle, and a main nozzle.

摘要： An IGV opening command is set based on an IGV opening A set by an exhaust gas temperature control section, an IGV opening B set by a compressor surge protective control section, and an IGV opening C set by an exhaust gas pressure protective control section. The value of the IGV opening A, or the value of the IGV opening B, whichever is higher, is selected, the higher selected value, or the value of the IGV opening C, whichever is lower, is selected, and the lower selected value is set as the IGV opening command (gas turbine back pressure rise avoidance priority mode). Alternatively, the value of the IGV opening A, or the value of the IGV opening C, whichever is lower, is selected, the lower selected value, or the value of the IGV opening B, whichever is higher, is selected, and the higher selected value is set as the IGV opening command (compressor surge avoidance priority mode). Alternatively, a switcher switches between these modes.

摘要： A combustion temperature high speed detection device is provided with a phase lead processing portion, thereby canceling out a detection lag of a temperature detector, and detecting the combustion gas temperature of a combustor at a high speed. The combustion temperature high speed detection device is also provided with a first-order lag filtering portion with a time constant of 0.25 second, a phase lag processing portion with a time constant of 10 seconds, a temperature change filtering portion with a cutoff frequency of 2 to 3 Hz, and a disturbance filtering portion including first-order lag filtering portions with different time constants and a high value selecting portion. Thus, high speed detection of the combustion gas temperature more suitable for a gas turbine system can be performed.

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.
