facturers make boilers that can fire either a combustible gas fuel or a fuel oil. Boilers that can burn two types of fuel are known as dual-fuel boilers. A facility normally considers a dual-fuel boiler if it has a critical end process. In the event that it loses the main source of fuel, it has a backup source of fuel available.
