Why doesn't the small hole in the real fire fireplace breathe fire?

The temperature type is influenced by the temperature. When the ambient temperature is low, the efficiency becomes worse, and even it can't work normally. Water-cooled engines are affected by circulating water. When the ambient temperature is low, the thermostat valve of the engine cannot open the external circulation, so it cannot provide the hot water needed for gasification. In this way, the gas discharged from the gasifier head is in the form of water mist, which cannot be ignited by electronic ignition, and it seems that there is an open flame that does not burn. It shows that the fuel is too wet and the water vapor content in the fuel gas is too high, which can be eliminated by switching to a drier fuel.
