Biomass Gasification
Sustainable Renewable Energy for Cambodian Rice Mills, Brick
& Tile Factories, Ice Making Enterprises and Manufacturing
Plants
What is Biomass Gasification ?Conversion of organic materials into
combustible gas mixture called SYN Gas or Producer Gas.
Involves partial combustion of biomassFour distinct processes occur in the
Gasifier as illustrated below:* Organic materials are living
organisms from plants and animals.
The Gasification Process
1. DryingRemoval of Water with Heat
2. PyrolysisDecomposition with heat
3. CombustionProcess of Burning/oxidation
4. ReductionOxygen lost and Hydrogen added
Biomass From Agro-Forestry Residues

Biomass Gasifiers SystemSize and Capacity
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
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
