The SOIMAR Group gasificators are of the fixed bed type and guarantee an optimum combination of thermo-chemical performance, syngas cleaning and simplicity of construction and maintenance.
There are four thermo-chemical processes that the combustion of biomass triggers:
- Desiccation (preheating of the biomass and elimination of the moisture it contains);
- Pyrolysis (decomposition of the desiccated biomass in the environment with little oxygen between 170°C and 850°C);
- Combustion (oxidation of the products derived from pyrolysis between 1,000°C and 1,100°C);
- Reduction reaction (by means of a carbon bed at 600°C – 800°C).
