A combustion chamber in which oil is the heat-producing fuel. Fuel oils, having from 18,000 to 20,000 Btu/lb (42–47 megajoules/kg), which is equivalent to 140,000 to 155,000 Btu/gal (39–43 megajoules/liter), are supplied commercially. The lower flash-point grades are used primarily in domestic and other furnaces without preheating. Grades having higher flash points are fired in burners equipped with preheaters. See also Fuel oil.

Domestic oil furnaces with automatic thermostat control usually operate intermittently, being either off or operating at maximum capacity. See also Oil burner.
