Backfire detection feature of gas type fire generator

摘要

(57) Abstract Objective Suppressing the damage by the backfire of the gas type fire generatorIt designates that it does as purpose. Constitution Tip/chip 11 of torch 11 of automatic gas preheating deviceThe thermocouple 1 which detects the temperature of b and, the automatic gas which was measured beforehandWhen the preheating device is operated normally, temperature of tip/chip 11bAt the same time it is higher and the damage by the backfire in tip/chip 11b is generatedIs lower than temperature of tip/chip 11b of the ru and the mushroom the base temperature whichWith the base temperature configuration section 3 which is configurated and aforementioned thermocouple 1 inspectionThe detection temperature which is put out was configurated to aforementioned base temperature configuration section 3When becoming larger than base temperature, the abnormal detection signal is outputIt has with ru abnormal sensing station 4. Advantages Generation of the backfire the damage be produced in the gas type fire generatorIt reaches the point where it can detect quickly before the ru.
