Coal Most industrial coal-fired boilers run on crushed coal, which burns more efficiently than large coal clumps. Gas and Oil Gas-fired boilers operate using natural gas, most often a mix of methane, ethane, butane, pentane, or propane. Boilers that run gasoline, diesel, and other petroleum-based fuels are typically classified as oil-fired boilers.
