Fire Tube Gas Boiler VS Water Tube Gas Boiler
Gas fired boiler is a very popular boiler type in many industry applications for its high efficiency and clean combustion, such as food & beverage, hotel, hospital, central heating, dairy industry, etc. While we see the boiler usually falls into two types: fire tube boiler and water tube boiler, so we also have two types of gas fired boilers to choose.
Fire tube gas fired boiler
In a fire tube boiler, the flue gas travels through the tubes, which are surrounded by hot water. Fire tube gas boilers are typically designed with either three or four sets of tubes (three- or four-pass boilers). Every set of tubes that the flue gas travels through is considered a “pass”. Boilers designed for three-passes have the stack at the rear, and boilers designed for four-passes have the stack at the front.

Our WNS series gas fire tube boiler is three-pass wet-back design, large combustion chamber, corrugated furnace design to increase the heat transfer area and strengthen heat transfer effect. What’s more, the WNS fire tube boiler is cooperated with Germany technology company, reaching a high industry level with great performance.
Water tube gas fired boiler
In a watertube boiler, water travels through tubes which are surrounded by the by-products of combustion, or flue gas. The water tube gas fired boiler is designed with two-drum D type layout. In the rear of the SZS series boiler, the flue gas condensate recovery device is equipped, effectively controlling the flue gas temperature and maximizing its thermal efficiency.
Fire tube VS water tube gas boiler
Compared to firetube designed boiler, the watertube gas boilers are safer by design, and it can operate many years longer than firetube boilers. Unlike the firetube gas boiler, a gas fired watertube boilers are available in larger capacities and recover faster than. In addition, watertube boilers can also handle higher pressures, and have the ability to reach very high temperatures with the use of superheaters, however, the firetube boilers cannot.
