Chafing fuel, sometimes spelled as “chafing fuel,” is a type of fuel used in chafing dishes or buffet warmers to keep food warm. It typically comes in small, portable cans or containers. Chafing fuel is designed to burn cleanly and safely, without producing smoke or odor. It’s commonly used in catering, buffet-style events, and food service settings where maintaining food at a consistent temperature is essential. The most common types of chafing fuels are gel-based, ethanol-based, or methanol-based. These fuels are often placed in a designated compartment beneath the chafing dish, where they’re ignited to generate heat.
