The principle is that gas enters the stove through the intake pipe, is adjusted by the gas valve (adjusted by the user via a knob), and then enters the burner head. At the same time, a portion of air is mixed in (this air is called primary air). These mixed gases are expelled through the flame distributor's orifices and ignited by the ignition device to form flames (the air required for combustion is called secondary air). These flames are used to heat cooking utensils placed on the pot support.

It's crucial to adjust the flame size during cooking. Technically, this requires the fuel to burn fully, and to provide the necessary secondary air promptly for the combustion, thereby rapidly enhancing preheating and improving thermal efficiency.
