Hello,

In your case, you should use DPM(discrete phase model). At the inlet boundary conditions, you can set the coal injections in the air flow.
Normally, coal & air flow is under combustion condition but if you don't want to reaction, you can disable the check of volumetric and surface reaction.

Anyany, the advanced tutorial related coal combutstion could be helpful to you.
I hope your work will be done well.

Ju Yong Ko.
