AUTO CONTROL LOOP : 

DCS AUTO CONTROL LOOP Coordinated control Total air control Super/reheater temperature control Mill out temperature control Hot well/heater /deaerator level control Drum level control Furnace draft control

INTERLOCK & PROTECTION : 

DCS INTERLOCK & PROTECTION Interlock & protection are used for safe startup /operation /shutdown /trip /of any equipment or auxiliaries, e.g. CW pump, ID Fan , FD fan, BFP, CEP, Mill ,PA FAN Heater Valve & drains

BOILER CONTROLS : 

DCS BOILER CONTROLS Burner management system Secondary air damper control Aux pressure desuper heating system Soot blower control Hp by pass

TURBINE CONTROL SYSTEM : 

DCS TURBINE CONTROL SYSTEM Turbine governing system Turbine protection Automatic turbine run up system Turbine stress controller Lp bypass Sequence controls for turbine driven BFP Generator aux monitoring

PERFORMANCE CALCULATION : 

DCS PERFORMANCE CALCULATION Boiler efficiency Turbine HP/IP/LP turbine Feed heaters Deaerator Condenser Air preheater Unit heat rate
