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

6 Syngas/Producer Gas - Composition Chemical Compounds Rice HuskWoody Biomass CO15-25%20-27% H2H % CH 4 Upto 4%Upto 3% N2N %45-50% CO % O2O %0-0.6% Gas C.V. (kcal/Nm 3 ) Above 1050Above 1100 Syngas generated per kg of biomass 2 Nm32.5 Nm3

7 Syngas Characteristics No Color Some Odor (distinct “burnt” smell) Some Impurities (Not Clean) Poisonous (Health Affecting)

8 Biomass Gasification Technology, Gasifier System Components and Design

9 Biomass Gasifier – Products WBG - Woody Biomass Gasifier FBG - Rice Husk Gasifier COMBO - Combination Biomass Gasifier

10 Bin Hopper Reactor Venturi Scrubber Heat Exchanger Demister Blower Filters Gas Line Gas Flare

11 Gasifier Body 1-Bunker 2- Hopper 3-Reactor 4-Dry Ash Conveyor 5-Rice Husk Elevator

12 Wet / Dry Blower 1- Blower suction adaptor 2- Water injection to wet blower 3- Observation window 4- Blower delivery/outlet 5- Manual gas control valve 6- Separation box gas inlet 7- Separation box 2 3 1

13 Hot and Cool Gas Lines 6 – Reactor Outlet box 7 – Venturi Scrubber 8 – Hot Gas Temperature 9 – Drain box 10 – Drain Tub

14 Safety Filter and Passive Filters

15 Coarse and Fine Filter Lines

16 Wastewater Treatment Plant Cooling Tower ALUM Settling Tank Sand Filter Charcoal Filter

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
