Butane fuel is a type of hydrocarbon gas that is commonly used as a fuel source. It is part of the alkane family and is often found in a gaseous state at room temperature. However, when compressed, it can be stored as a liquid in canisters, making it convenient for various applications. This fuel is widely used in portable stoves, lighters, and camping equipment due to its efficiency and ease of use. Butane burns cleanly, producing minimal smoke and pollutants, which makes it a popular choice for both indoor and outdoor cooking.
