We use CASECAD loop to inhance the capability of the
process.normally we use this loop at BFW(boiler feed water)
tanks and at the BMS(burner managment system)to inhance the
burning ratio of fuel that become more relaiable for our
firing.because we are using here two controller(two
setpoints)these both controller makes process much more
flexible and accurate.

Using cascade control enhance loop stability, as the
controller generatea corrective signal in case of any change
in process load - we don't need to wait till we got a
problem in the measured process variable (pressure,
temperature, ..)
