I'm planning to replace some of my band heaters (those near the funnel) with an LPG stove. I will use solenoid valve via thermocontroller to control the switching of flame. I will also make a bypass hose (bypassing the solenoid) with control, to have a small flame constantly burning so as to eliminate the need for firing up the stove everytime the solenoid switches on.
My concern is, if in case the small flame is accidentally extinguished, and the stove is turned on, the LPG will leak and might cause flame.
I use to own a gas fired clothes dryer. The technician told me that if in case the piezo failed to light up a flame, or the flame was accidentally extinguished, the LPG supply will automatically be cut-off. Is the principle applicable in my project? What do you call the flame detector or whatever it's called? Or do you have other ideas for such application?
