Abstract
PURPOSE: To eliminate a necessity of a pilot burner, simplify constitution and to exclude insecure safety by a method wherein an exothermic thermo sensitive element is used both as an ignition heater and as a temperature sensor, while preventing it from making a comeback as an ignition heater when going out.
CONSTITUTION: A contact 58 interlocking a gas cock is closed, an exothermic thermo sensitive element 57 consisting of SiC is made into an ignition heater being heated by letting flow high power current to it and a level detection circuit E signalizes the valve opening by a resistance change when reaching about 1200°C above the burning set temperature and ignites on opening a valve 55 by a power transformer 104. After opening the valve and after the time set by a time circuit G, the relay 94 of the relay driving circuit is excited to open the contacts 95, 96 and the element 57 is used as the temperature sensor by minimizing its current and controlling heating at about 950°C above the burning set temperature. When extinguishing a flame and the element 57 is cooled down to under the burning set temperature, the level detection circuit E signalizes the opening of the valve 55 and after the opening of the valve 55, a latch circuit 1 checks the automatic comeback of the element 57 as the ignition heater.
