The proposed cogen power plant has been thus designed to be implemented by installing a extraction cum condensing 30 MW turbine.
The cane crushing capacity has been estimated to stabilize to 82 TCH at 22 hours / day basis and 160 days of crushing from 2004 onwards, or around 6.2 lakh MT of cane crushing per year.
Bagasse generation, usage for bagaciiio / handling losses and available for boiler as fuel, have been respectively estimated at 29%, 1% and 28% of cane crushed.
Steam consumption for sugar mill has been taken at total 49 % on cane with 3 % on cine for MP steam" and 46 % on cane for LP steam for process requirements, as per the design of the sugar plant equipment and guarantees offered by the equipment supplier.
Moisture content of wet mill bagasse has been estimated at average 50%.
The cogen power plant will work for 160 season days, with 1 x 120 TPH boiler, 86 kg/cm2 and 515 deg. C and 1 x 30 MW TG sets.
Power consumption for sugar process has been estimated at 27 kwh / TCH
