Boiler Material - IBLS

This depends on the material used in the boiler shell & firebox. Most small loco boilers are made of copper and for these boilers the best stay material is also copper. This is to avoid wasting away in the water space due to electrolysis. This action takes place when dissimilar metals are in contact and submerged in the boiler water.

Fire-tube boiler - Wikipedia

A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or 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. The fire-tube boiler developed as the third of the four major historical types of boilers: low-pressure tank or "haystack" boilers, flued boilers with one or two large flues, fire-tube boilers with many small tubes

Material for Fire Tube - Boiler and Pressure Vessel

These fire tubes are conected to a burner at one end, which delivers a 2.5m long flame with 750mm in diam, 1.6E6 Kcal/h and which has 2000°C at its hotest point (inside feather). For protecting the fire tubes from the flame there is another inside tube (length= 3m) made of Incoloy or Inconel. I'm wondering why do they use this material??
