14/6/2012 · I think the 'key' is Fisher's in statement in the header "to control or reduce steam temperature." Attemporators just knock the temperature down a little bit, and I don't remember them being real fine control, while desuperheaters have to control to a very fine point to avoid going below the sat line and have to control to this point often with the amount of SH upstream of the DSH varying.

Boiler and Diesel Tubes | Powerteksolutions

An attemperator is used for regulating the steam temperature of the boiler. A desuperheater is usually located downstream from the boiler where saturated steam would be useful. While an attemperator is allocated close to the boiler where high temperatures could have an impact on the walls or surfaces which would, in turn, have an impact on the process operation.
