Steam Temperature Control | Control Notes

Modern boilers raise the steam temperature to around 1000F (538C), which approaches the creep (slow deformation) point of the steel making up the superheater tubing. Steam temperatures above this level, even for brief periods of time, can shorten the usable life of the boiler. CASCADED STEAM TEMPERATURE CONTROL.
