Incomplete Combustion of Methane
2CH4 + 3O2 → 2CO + 4H2O
概要
When methane burns in insufficient oxygen, carbon monoxide forms instead of carbon dioxide. This incomplete combustion is dangerous because CO is a toxic, odorless gas. Poorly ventilated gas appliances can produce CO, leading to carbon monoxide poisoning.
