Superheaters - an overview | ScienceDirect Topics

Superheater tubes have steam on one side and hot combustion gases on the other. Surface temperatures are higher here than the boiler tubes. The passage of heat from the hot flue gases through the tube wall increases the temperature to about 565°C. The construction material of tubes depends on the final steam temperature achieved.
