SMALL–MEDIUM-LARGE SCALE BIOMASS POWER – BASED ON MODULAR CONCEPT
CAPACITY-50Nm3/hr to 8000Nm3/hr – 60000Kcal/HR to 10,000.000Kcal/HR – 5KWE to 2000KWE
GASIFIER'S TYPE: Fluidized Bed -- UPDraft / Down Draft / Twin Fire Fixed Bed Gasifier
WASTE HANDLED |
- | Rice Husk, Wood Chips, Saw Dust Bark, Wood Waste Forest Residue, Rice Straw, Wheat Straw, Cotton Straw, Corn Stalk, Corn Cob, Bagasse, Peat, Cocoa Husk, Coconut Shell, Bamboo Waste, Willow, RDF Pellets, Empty Fruit Bunch, Palam Kernel, Paper Mill, Shell Waste etc |
SALIENT FEATURES |
- | Faster & more precise Temperature Control- Handling of Irregular shaped feed stock - Rapid start up and program change Low Pressure drop allowing producer gas recirculation for max Turn Down Ratio > 50% - Temp. of Gas at Gasifier Outlet 300 to 500 Moisture content(%) <18% - Ash Content <3% - Hot Gas Mode Efficiency >90% - Cold Gas Mode Efficiency >85% Smaller size with easy installation - Simplicity in operation and care of Automation due to absence of log in process control. |
