The last reactions considered in the modeling were reactions R7 and R8. They are both exothermal and therefore
are useful to guarantee the autothermicity of the process, however, they are in some way undesirable as imply a
consumption of useful gas products. As indicated by the respective equations, in both this reaction it is involved
oxygen, which is fed to the two reaction chambers at different flow rate, therefore the right compositions of the
gasifying mediums provided to the two reaction chamber of the gasifier is a parameter with important consequences
on the quality of the produced gas.
