Why do gas stoves smoke your eyes?

When the valve of the gas stove is not properly adjusted and the oxygen is insufficient, the smoke containing a large number of carbon molecules will be formed, which will not only make the bottom of the pot black, but also make the eyes uncomfortable. Therefore, it is necessary to adjust the valve to make the flame return to normal and become a neutral flame, so that black smoke will not be emitted. Gas stoves are on and don't burn, which generally won't make people cry. Gases are dangerous if they are not burned. If it is gas, it will be poisoned. Gas itself is tasteless. Liquefied petroleum gas and natural gas are generally non-toxic and tasteless, but they are both dangerous and combustible. When it does not burn, it generally does not make people cry, but this combustible gas is often mixed with other components with special odor as a warning reminder of gas leakage. In order to ensure the safety of gas use, all three gas sources are odorized to remind users in time when accidents such as gas leakage occur. The increase in the concentration of odor additives may cause irritating eye reactions to users, but this additive is harmless to people. If gas poisoning is found, users should be moved to a place with sufficient ventilation and oxygen. Users with mild gas poisoning should breathe fresh air. If there is an oxygen machine at home, they can take oxygen locally. Users with severe gas poisoning should go to the nearest hospital for treatment. Precautions for natural gas use: users need to regularly check the joints, switches, hoses and other parts of natural gas equipment with soapy water to see if there is any air leakage, and do not use matches to detect air leakage. If bubbles or natural smells are found, all switches should be turned off, kindling (including light switches) is strictly prohibited, windows should be opened for ventilation, and the local natural gas maintenance station should be reported immediately.
