Why Boiler Designers Use Different Materials in

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
