Carbon dioxide and water vapor come from a flame.
No, the presence of a continuous flame on oil drilling rigs depends on the specific equipment and processes being used. Some rigs may use a flare system to burn off excess gas or emissions, while others may not have a visible flame at all times.
To do the burning splint test, you light a wooden splint and then blow it out to create an ember. You then place the splint near a gas sample without touching it. If the gas is flammable, it will ignite and produce a flame when the ember from the splint comes into contact with it.
A gas furnace pilot flame stays burning by receiving a constant flow of gas from the pilot light assembly. The pilot light assembly contains a thermocouple that detects the presence of the pilot flame. If the flame goes out, the thermocouple signals the gas valve to shut off, preventing any gas leaks.
The flame goes out because you turned it off.
Gas is invisible because of the substances it has comined with. Not all gases are invisible. Some are poisionis and some are harmless. Gas can be of just water vaper. If the gas molecules combine into a larger size they may fall and it would not be called a gas substance any more.

After a natural gas well is drilled there will be a flame that comes out of the well for a while. This is so the pressure and flow of the gas can be tested. It is called gas flaring. It also burns off excess gas that might not be captured when they are collecting the gas.
The flame of a candle requires oxygen to continue burning. When you cut off the air supply, the flame is deprived of oxygen which is essential for the combustion process. Without oxygen, the flame cannot sustain itself and eventually dies out.
A thermocouple is a device used to sense the flame of a pilot light. IF the pilot light is not burning, the thermocouple does not permit the main flow of gas to the gas logs. Thermocouples DO wear out, are relatively cheap, and are made to be replaced.
It is supposed to quit burning.
If you blow out the flame without turning off the gas, gas continues to flow. Exposure to too much gas can kill you.
If a flame is present with the gas valve off, it indicates a potential issue with the gas control valve or a gas leak. In this situation, it is important to immediately shut off the gas supply, ventilate the area, and contact a qualified technician to inspect and repair the gas appliance.
