The excess electricity capacity which once characterised South Africa’s energy profile has come to an end! The country now urgently needs to invest in new capacity and new ideas. Africa’s challenge is that it inhabits 12% of the world’s population, but only produces 2% of the world’s electricity!

What is Biomass Gasification?

•Biomass Gasification is a conversion of solid fuel (wood, wood waste, agricultural residues etc.) into a combustible Gas mixture commonly known as Producer Gas.

•Gasification is a Chemical Reaction where various complex physical and chemical processes take place. Biomass gets dried, heated, pyrolysed, partially oxidized and reduced as it flows through the Gasifier.

• Four distinct processes take place:-

1.Drying

2.Pyrolysis

3.Combustion

4.Reduction

Although there is considerable overlap, each Process can be considered to be occupying a separate zone, in which fundamentally different chemical and thermal reactions take place. The fuel must pass through all of these zones to be completely converted to Tar Free Producer Gas.
