Methanol
coal is a fossil fuel that burns without giving water vapour.
An example of a motor that burns fuel without air is a solid fuel rocket motor. These motors contain both fuel and oxidizer within the fuel itself, allowing combustion to occur without the need for external air.

That's the motor, which burns fuel and propels the boat.
An internal combustion engine burns fuel inside.
It burns with oxygen. That's all.
Carbon monoxide and methane
Fire does not burn, its whatever if fueling the fire that burns. For example, wood is a fuel that burns, and fire is the result. The speed at which a fuel burns, depends on the fuel. i.e. Wood burns much slower than gasoline.
Fossil fuel
Char or charcoal is the remaining portion of the wood material that contains unburnable minerals and pure carbon. Charcoal fire emits no smoke as it is the residue of the wood as carbon without the gases
Anything which burns requires O2, so oxygen is required for fuel to burn. Also this is known as a combustion reaction and an exothermic reaction.
When fuel burns without enough oxygen, it produces carbon monoxide (CO) in addition to carbon dioxide (CO2). Carbon monoxide is a colorless, odorless gas that is toxic to humans and animals when inhaled in large amounts. It interferes with the body's ability to carry oxygen in the blood, leading to potential health risks.
