摘要： PURPOSE:To improve reliability of a combustion monitoring device by obtaining the exhaust gas temperature allowable width as the function of the fuel flow rate indication signal. CONSTITUTION:A plurality of exhaust gas temperature sensors 6 are installed, and the average value TXM is calculated from a plurality of detection values. The exhaust gas temperature allowable width TD is obtained from the fuel flow rate indication signal F. It is monitored if each of a plurality of detection values is within a range of TXM+TD or not, and when the detection value is larger, an alarm 9 is generated. Therefore, reliability of the combustion monitoring device can be improved.

摘要： PURPOSE:To prevent a surge from occurring by opening a main exhaust duct and closing a blow-off duct instead after compressor discharge pressure becomes more than back pressure at time of stating. CONSTITUTION:A first exhaust damper 3 is installed in a main exhaust damper 5, and a second exhaust damper 8 is installed in a blow-off duct 7 as well. Starting takes place in the state that the first exhaust damper 3 is closed and the second exhaust damper 8 is opened. On and after that point that compressor discharge pressure becomes more than back pressure, the first exhaust damper 3 is opened and the second exhaust damper 8 is closed. With this constitution, a turbine can be started without generating any surge even at time of high back pressure generation.

摘要： PURPOSE:To suppress the load fluctuation when multiple fuels are switched by using the electric power generated by a generator as the feedback signal to be compared with the fuel flow preset signal and setting the variation signal to the new fuel flow preset signal. CONSTITUTION:Normally, the B fuel 8 corresponding to the fuel flow preset signal 2 is fed to a combustor 10 via a flow controller 5 and mixed with the air from a compressor 9 for combustion. The combustion gas is fed to a turbine 11 to drive a generator 6. On the other hand, when the B fuel 8 is switched to the A fuel 7, the signal from a distributor 3 is sent to controllers 5 to increase the A fuel 7 and decrease the B fuel 8. In this case, the electric power signal generated by the generator 6 is used as the feedback signal and compared with the load preset signal 1 by a comparator 12. The variation signal from the comparator 12 is fed to the fuel flow preset signal 2, and the new fuel flow preset signal is fed to the distributor 3.

摘要： PURPOSE:To effectively regulate the load, by performing load regulation through regulation of the flow rate of fuel onto a gas turbine by means of a flow regulating valve and simultaneously regulating the coal charge onto a gasifier oven while detecting the variation of the pressure in the gasifier oven. CONSTITUTION:When a load set 1 is given, it is compared with the currently generated power amt. of a generator 2. To correct any deviation, a signal 12 is conveyed to a fuel flow rate regulating valve 9, thereby regulating the opening of the valve. This increases or decreases the coal gas flow rate into a gas turbine combustor 4, and a load setting is performed. On the other hand, since the initial pressures in a coal gasifier oven and a coal gas purifier 3 vary with time by regulating the coal gas flow rate into the gas turbine combustor 4, the pressure variation rate against time is detected and on the basis of the pressure variation rate, the coal charge amt. into the coal gasifier oven 3 is controlled, thereby regulating the loads in the coal gasifier oven and coal gas purifier 3.
