CAPTIVE POWER PLANT: The proposed Captive Power Plant (CPP) is configured with 2 Nos CFBC Boilers and 2 Nos. Steam
Turbine generating 30 MW each. The proposed plant shall be configured with two Multifuel Fired CFBC
Boilers each capable to generate 130 TPH steam at 515 ±5 deg. Cent. The proposed 2x30 MW Steam
Turbine shall have three regenerative heaters (HP Heater, LP Heater and De-aerator) to improve the cycle
efficiency of Power Plant. The Proposed Steam Turbines shall have Air Cooled Condenser for condensing
the exhaust steam. Dense Phase pneumatic Ash Handling System shall be used for conveying the Fly Ash
and Bed Ash generated in the boilers to respective Ash silos.
