Does carbon dioxide support the combustion of fuels such as wood?

Carbon dioxide (CO2) does not support the combustion of fuels such as wood. In fact, CO2 is a product of combustion and its presence can actually inhibit the combustion process.

For combustion to occur, three elements must be present: fuel, oxygen, and heat. Carbon dioxide is not a fuel, and it does not provide oxygen or heat. Therefore, it cannot support the combustion of fuels.

In fact, the presence of CO2 can actually inhibit the combustion process by displacing oxygen from the air. This can make it more difficult for the fuel to react with oxygen and produce heat, which is necessary for combustion to occur.

For these reasons, carbon dioxide is not used as a fuel or as a means to support the combustion of fuels.
