Methane burning
Web25 mrt. 2024 · When methane burns in the air it has a blue flame. In sufficient amounts of oxygen, methane burns to give off carbon dioxide (CO2) and water (H2O). When it undergoes combustion it produces a great amount of heat, which makes it very useful as a fuel source. Methane is a very effective greenhouse gas. WebMethane is a potent greenhouse gas — 28 times more potent than CO 2 over 100 years. It can be turned into CO 2 by simply burning it, reducing its global warming potential …
