Fire Tube Gas and Oil Boiler VS Water Tube Gas and Oil Boiler


Gas and oil boilers fall into two categories: fire tube and water tube. Boilers in which flue gas flows through the tubes and water surrounds the tubes, are called as fire tube boilers; the boilers in which water circulates through the tubes, which combustion gases surround the tubes, are called as water tube boilers.
