PURPOSE:To improve the partial load efficiency by always holding the combustion temperature at an expected value (allowable max. value) when under a partial load. CONSTITUTION:A signal PS from an atmospheric pressure generator 14 is multiplied by an output (planned air flow rate) WAS of a signal generator 15 with a multiplier 16. Then, the results are multiplied by a signal from an atmospheric temperature detector 17 with a multiplier 19. The results are added to a signal from a signal generator 20 with an adder 21 to determine an air flow rate WA depending on the ambient conditions. The air flow rate is multiplied by a signal TX from an exhaust gas temperature detector 23 with a multiplier 24 to calculate a combustion temperature TF. The signal TF thus obtained is converted into an inlet guide vane signal (set value) with a function generator 25 so as to give the highest combustion temperature at the time and further processed with a subtractor 27 according to the signal (measured value) M1 of the inlet guide vane opening transmitter 26 and an inlet guide vane opening command signal is formed with a proportional integrator 28. |
