16 LoCAL Plus : Power generation efficiency Hitachi Zosen India has developed standard WtE plant for Indian market: LoCAL Plus Design Point: Waste throughput 600t/d Net calorific value 1650 kcal/kg Power generation 11.5MW Total waste quantity: W kg/h Net Calorific Value: NCV kcal/kg. Energy recovery potential (kwh) = 25,000 kg/h = 600t/d = 1,650 kcal/kg = 1.16 x 10-3 x NCV x W = 1.16 x 10-3 x 1,650 x 25,000 = 47,850 kw Power generation (kw) = 11,500 kw Power generation efficiency (%) = 11,500 / 47,850 x 100 = 24.0 Copyright Hitachi Zosen Corp. 16
