Product Description
Fire tube boiler is also referred to as smoke tube boiler or fire tube shell boiler, which is a type of boiler in which hot gases from a fire pass through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.

Horizontal fire tube boiler applications
Fire tube boilers can be used in steam or hot water applications, such as food & beverage, paper & pulp, laundry, tanneries, textile, packaging, wood, machinery factory, metallurgical plants, infrastructure & bitumen, plastic & rubber, chemical, pharmaceutical , power plant, district heating and large buildings heating.

Three-pass fire tube boiler designs
Fire tube boilers are typically designed with three sets of tubes (three-pass boilers). Every set of tubes that the flue gas travels through is considered a "pass". A boiler with more passes has a higher heat extraction rate and is more efficient then one with less passes. The three pass fire tube boilers are high combustion efficiency and energy saving.
