Abstract

PURPOSE:To stabilize control action after starting is all over by judging the starting or its completion of an air feeder with rise and fall of a combustion air flow signal, changing a gain in a computing element before and after the starting completion, and maintaining a response speed of the control action at the time of starting. CONSTITUTION:Detection signals 15, 17, and 19 out of a combustion air flow detector 14, an air pressure detector 16 and an air temperature detector 18 are compensated by a compensator 20 and inputted into a computing element 30. On the other hand, as for detection signal 23 out of a detector 22 and a fuel flow command signal 25 out of a fuel controller 24 for an auxiliary burner, a high value signal 27 is selected by a high value preferential circuit 26, and it is inputted into a flow function generator 28, while a fuel air quantity to the signal 27 is operated, and a fuel air flow command signal 29 is inputted into the computing element 30. Then, this computing element 30 outputs a valve opening regulating signal 31 is accordance with a deviation of the inputted signal and a gain signal 33, regulating a valve 8, and the air quantity is controlled. On the other hand, a gain function generator 32 judges starting or its completion of an air feeder from rise and fall of the signal 15, outputting the gain signal 33 and changing a gain of the computing element 30.
