During CMC mode the demand is applied parallel to BM and TM. The response
of boiler will be slow when compared to turbine. This will create deviation in
boiler loops, such as Fuel flow controller, Air flow controller, Steam
temperature controller, Drum level controller, etc. It is not advisable to
continue load change with a high deviation. The change in load demand will be
blocked until the deviation become less.Load block will be applied for Load
Increase and Load Decrease. Alarm will be initiated to alert the operator.
