Do you know anything about the principles of gas nozzles and air valves in gas stoves?
Thread Content
The air intake nozzle and the damper of the gas stove are combined; gas and air enter the stove at the same time. It’s unclear why the gas doesn’t leak out through the damper, but rather it is drawn in due to the negative pressure created at the gas nozzle. Do you know what principle this is based on?
It operates on a principle similar to jetting and venturi effect. Aerodynamics is explained clearly; in chemical engineering, it’s sufficient to just know the phenomena that occur
Based on the conditions for burning gas in air, the adjustment of the damper is related to the flow velocity of the gas stream at the nozzle. The greater the flow rate, the more air will be drawn in through the damper. For some large industrial gas nozzles, the \"air\" required also needs to have a certain pressure applied to it in order to achieve a sufficient flow rate for combustion. Additionally, the “burner” is composed of the auxiliary combustion gas provided by the damper and the combustion gas provided by the nozzle. The internal flow channels that make up this burner also have some special requirements. For reference.
