Fire-tube boiler - Wikipedia

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.
