Boundary conditions used in the model.
| Inlet | Mass flow inlets for air nozzles and biomass feed |
| Always supposed as normal to boundary | |
| Outlet | Two exits for syngas zero-gauge pressure |
| Back flow temperature was assumed 1000 K | |
| Walls | Stationary walls |
| Turbulence | For assuring fully developed flows for air and biomass feeding, the turbulence is identified by the intensity and hydraulic diameter |
