2. What is Biomass Gasification ? Conversion of organic materials into combustible gas mixture called SYN Gas or Producer Gas. Involves partial combustion of biomass Four distinct processes occur in the Gasifier as illustrated below: * Organic materials are living organisms from plants and animals.

3. The Gasification Process 1. Drying Removal of Water with Heat 2. Pyrolysis Decomposition with heat 3. Combustion Process of Burning/oxidation 4. Reduction Oxygen lost and Hydrogen added

4. Biomass From Agro-Forestry Residues Woody/Bamboo pieces or Chips Rice Husk Nut Shell like Coconut, Peanut Corn Cob Sugarcane Baggasse Cashew Nut Shell Agriculture Waste Wood Corn Cobs Rice Husk

5. Syngas or Producer Gas (Chemical Formula) N 2 Nitrogen CO Carbon Monoxide H 2 Hydrogen CO 2 Carbon Dioxide CH 4 Methane O 2 Oxygen

17. Biomass Gasifiers System Size and Capacity

18. CAPACITY of BIOMASS GASIFIERS 1. Using Rice Husk Fuel = FBG Type Gasifier 2. Using Woody Fuel = WBG Type Gasifier 3. Using Rice Husk and Woody Fuel = COMBO Gasifier ANKUR Model Sizes FBG : 40, 60, 80, 100, 120, 150, 200, 250, 300, 350, 400, 500, 600, 700, 850 The Largest Size “ANKUR” Type Rice Husk Gasifier is FBG 850

19. How to Calculate the Size A Gasifier Running in Dual Fuel Mode. ( 30% Diesel and 70% Syngas) Biomass Capacity Table for ANKUR Gasifiers 1. FBG 100 = 120 kg husk per hour 2. FBG 150 = 180 kg husk per hour 3. FBG 200 = 240 kg husk per hour 4. FBG 300 = 360 kg husk per hour 5. FBG 400 = 480 kg husk per hour 6. FBG 500 = 600 kg husk per hour 7. FBG 600 = 720 kg husk per hour 8. FBG 700 = 840 kg husk per hour 9. FBG 850 = 1,020 kg husk per hour
