I am using of9, ReactingFoam, to simulate coal powder combustion. As I am simulating rich fuel combustion, I need it to generate CO instead of CO2. Therefore, I have modified the SurfaceReactionModel. Originally, I wanted to modify it to three reactions: C+0.5O2=CO, C+CO2=2CO, and C+H2O=CO+H2, but there was an error. Therefore, I only modified it to C+0.5O2=CO, which is not a problem, but the temperature field is incorrect. I limited the temperature to 1550k, and the temperature of the entire burner is 1550k. What is the reason? I have placed my modified files and temperature maps below. The inlet of the burner is on the left side.
And even if I don't change the SurfaceReactionModel, my flame position is too far back and cannot burn near the air inlet. I tried using toposet to create ignitionCells, but it didn't work.
Do you know what the reason is?
Thank you for any help.

My predecessors used fluent, and the results of using the Euler Lagrangian method were similar to the position where I burned, but the Euler method was able to ignite at the air inlet. Is this the key point? Can Openfoam use the Euler Euler method to simulate coal powder combustion?

Hi, does anyone know about this problem?
