Difference between Attemperator and De-superheater

Attemperator are fitted in order to keep the steam temperature in the final stages of the superheater within certain desired limits . This is done for two main reasons . 1. The most important is the protection of the superheater tube material from the effects of overheating. *Mild steel superheater tubes tubes should not be subjected to steam temperatures in excess of 455℃. 2. The formation of bonded deposits on superheater tubes can be reduced if steam and gas streams within certain temperature ranges are prevented from coming into contact of each other. De-Superheater is used to reduce the temperature of a quantity of superheated steam and make it suitable for used in auxiliary services requires low temperature or saturated steam . *The reason for doing this way rather than by taking the saturated steam direct from steam drum , is to protect the superheater , these must be protected against overheating under all conditions of load by circulating steam through them . *Al...
