Water-tube boiler - Wikipedia

A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes.In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes

4 Different Designs of the Fire Tube Boiler: Which Is Best

The diameter of the furnace plays an important role in the design of the boiler. Because it is the area directly exposed to the flame, it absorbs the most heat and as a result, it is the material with the greatest heat fatigue coefficient. The greater the diameter of the furnace, the lower the heat fatigue coefficient, the less material fatigue, and as a result, the longer the useful life.
