The Gasification Process

1. Drying. Drying takes place in the uppermost portion of the Gasifier through heat transferred
from the high-temperature combustion zone
below. Moisture in the feedstock is released
in the form of water vapour.

2. Pyrolysis. Heating in the absence of oxygen at temperatures above 200 ̊c results in the chemical decomposition of organic materials. During pyrolysis, volatiles are released in the form of gas and char is produced.

3. Combustion. Controlled oxygen is added to the fuel and oxidation/ burning occurs, releasing heat and energy.

4. Reduction. Combustion products,
Gas comprising mainly carbon dioxide and water vapour, are reduced in the presence of high-temperature carbon to produce carbon monoxide and hydrogen.

What is Gasification?

Gasification is the process of transforming waste materials, known as feedstock, into clean, green, sustainable energy.

A gasifier is essentially a chemical reactor in which the feedstock is dried, heated, pyrolyzed, partially oxidised and reduced as it flows through the system.

The resulting combustible gas mixture, known as ‘syngas’ is filtered and can be used to produce electricity, heat, gas or liquid fuel for such thermal applications as hot air generators, dryers, boilers, thermic fluid heaters, ovens, furnaces and kilns.
