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.

Superheaters in boilers have all modes of heat transfer in boiler. They also have a very high length through which the total pick up steam temperature takes places at each unit length. The length of tube and temperature pick-up needed to raise the steam to the required level of super heating calls for using different materials along the total length. These changes in material will have to be

Mar 04, 2018· Corrosion reduces the lifetime of super heater tubes more than any other cause. It can be minimized by the careful selection of those materials that are most resistant to corrosion under operating conditions. Also the selection of material also de

A shell and tube heat exchanger is a class of heat exchanger designs. It is the most common type of heat exchanger in oil refineries and other large chemical processes, and is suited for higher-pressure applications. As its name implies, this type of heat exchanger consists of a shell (a large pressure vessel) with a bundle of tubes inside it
