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： In a heating apparatus for heating the air sucked into a gas turbine by a heat exchanger, the temperature fluctuation of the heated air is suppressed even in the period, for which a steam source to be fed to the heat exchanger is changed. For suppression, a heat exchanger is fed with both a self-can steam, the feed rate of which is controlled by a self-can steam control valve, and the auxiliary-steam, the feed rate of which is controlled by an auxiliary-steam control valve. At starting time, the quantity of the auxiliary-steam is reduced at a constant rate, and that of the self-can steam is increased while a feedback control and a feedforward control are being made. At stopping time, the quantity of the self-can steam is reduced at a constant rate, and that of the auxiliary-steam is increased while the feedback control and the feedforward control are being made.

摘要： In a heating apparatus for heating the air sucked into a gas turbine by a heat exchanger, the temperature fluctuation of the heated air is suppressed even in the period, for which a steam source to be fed to the heat exchanger is changed. For that suppression, a heat exchanger (30) is fed with both a self-can steam (S1), the feed rate of which is controlled by a self-can steam control valve (41), and the auxiliary-steam (S2), the feed rate of which is controlled by an auxiliary-steam control valve (51). At the starting time, the quantity of the auxiliary-steam (S2) is reduced at a constant rate, and the quantity of the self-can steam (S1) is increased while a feedback control and a feedforward control are being made. At the stopping time, the quantity of the self-can steam (S1) is reduced at a constant rate, and the quantity of the auxiliary-steam (S2) is increased while the feedback control and the feedforward control are being made.

摘要： The blast furnace gas burning facility prevents a wet type dust collector from freezing under such conditions that the temperature of blast furnace gas does not exceed the freezing lower-limit temperature of the wet type dust collector. The blast furnace gas burning facility 1 burns blast furnace gas discharged from a blast furnace by supplying the gas to a combustor 2 after removing dust with a wet type dust collector 7 and compressing the gas with a compressor 8. A fuel-gas heating channel 12 is disposed between the outlet side of the compressor and the inlet side of the wet type dust collector. When the temperature of the blast furnace gas flowing into the wet type dust collector is lower than a lower limit temperature, a high-temperature, high-pressure gas compressed by the compressor is diverged and supplied into the inlet side of the wet type dust collector.

摘要： An engine switch for selectively starting and stopping an engine and an LED for irradiating the engine switch are located in a passenger compartment of a vehicle. When a vehicular lighting device, such as a headlight, is switched from an on state to an off state, the LED is lighted up. Therefore, even if the passenger compartment is dark, the position of the engine switch is easily found.

摘要： A gate-type shift lever device having a stopper which is disposed so as to prevent the movement of a shift lever positioned in one of the P shift range and N shift range and which, in this case, prevents the movement of the shift lever positioned in the P shift range to other shift ranges than the P shift range, and the movement of the shift lever positioned in the N shift range to the R shift range. This makes it possible to reliably set a shift lever in a shift lock state under a specific condition without effecting a pushing operation of a shift lever knob and by a simple structure.

摘要： A gas turbine is driven by a combustion gas produced when BFG compressed by a gas compressor and air compressed by a compressor are burned in a combustor. Steam is generated from a waste heat boiler by utilization of heat of an exhaust gas from the gas turbine, and a steam turbine is driven by this steam. An electric generator generates electricity upon driving of the turbines. A condensing heat exchanger is disposed in an air intake duct, and part of steam from the waste heat boiler flows through the heat exchanger to heat intake air. The amount of steam that flows through the heat exchanger is adjusted by adjusting the degree of opening of a steam control valve by a control device. By so doing, the ignition performance of the gas turbine in a BFG-fired gas turbine combined cycle plant is enhanced even in an extremely cold district.
