What is Gasification?

Biomas —> (Gasification) —> Producer Gas

Basic Process Chemistry
Conversion of solid fuels into combustible gas mixture called producer gas (CO + H2 + CH4)
Involves partial combustion of biomass

Why Biomass Gasification?

Gasification is a -

• Highly Efficient Process
• Can be applied over a range of output ratings (few to hundreds of kWs)
• Can be used for thermal applications & electricity generation
• Low initial investment and cost of power production

Producer Gas

• allows better process control and convenience
• Cleaner combustion in connected equipment
• Elimination of all pollution related to Biomass use
  

Gasification - Schematic

Gasifier

The Gasifier is essentially a chemical reactor where various complex physical and chemical processes take place. Biomass gets dried, heated, pyrolysed, partially oxidized and reduced in this reactor as it flows through it. Four distinct processes take place in a gasifier:

1. Drying of the fuel.
2. Pyrolysis.
3. Combustion.
4. Reduction.
