The present problem simulates the combustion process inside a gasifier chamber. The material used for combustion is biomass, which reacts with the oxidizer. It is a biomass substance made from wheat straw that reacts with oxygen to produce synthetic gas as a healthy fuel. Since in this simulation, the combustion reaction between biomass and oxidant occurs and various gas species are involved in the process as reactants or products, the Species Transport model has been used, and by activating the reaction within it, a Non-Premixed type reaction model has been used.

In the present model, fuel containing biomass and air enters the chamber from two separate inlets from the upper area and creates a mass of materials including ash and semi-combustible coal in the lower part of the chamber. Finally, the resulting gas is discharged from the outlet at the bottom of the chamber to the next stage, entering the relevant boiler to create the combustion process. Also, the incoming fuel must enter the chamber as discrete p
