Abstract

PURPOSE: To work a combustor on safe side by a control system in which an electromagnetic valve is controlled by providing a square wave generator circuit and a differentiating circuit so as not to send forth output pulse when parts are out of order.
CONSTITUTION: A combustor controller, consisting of a flame detection circuit A, a flame detection control circuit B, a timer circuit E, and an electromagnetic valve control circuit C, is provided with a square wave generator circuit D consisting of a diode 8 and a resistance 9 and to generate square wave synchronizing with AC current and a differentiating circuit F consisting of a diode 30 and a resistance 30. Square wave generated from the square wave generator circuit D is joined with the input of the timer circuit E, and its output is differentiated in the differentiating circuit F to form a pulse wave form which is in turn put in SCR52 of the electromagnetic valve control C. Then, the electromagnetic valve 33 is opened and ignition is made by an ingnitor. When no flame exists, SCR52 becomes OFF because no voltage is generated in the differentiating circuit F and thereby the electromagnetic valve 33 is closed to interrupt the supply of fuel.
