Cascade, Feed Forward and Three-Element Control controlguru. By Allen D. Houtz 1. One common application of cascade control combined with feed forward control is in level control systems for boiler steam drums. The control strategies now used in modern industrial boiler systems had their beginnings on shipboard steam propulsion boilers.

Why chemical system is required for boiler feed water

Answer: Because water is corrosive to steel, especially in an acidic state which can be exacerbated by oxygen and CO2 in the water. Boiler treatment gives the right alkalinity, pH and sludge drop out (to prevent scaling of the internals) to keep the boiler in good condition. Other treatments rem
