Hi there:

I tried multi injection. However, when I defined the combusting particles as coal-mv for the first injection (injection-0), there is only coal-mv is show on the list for next injections with combusting particles.

Since I also want to inject other biofuels besides coal from different places, what should I do now?

Thank you so much for your time and answer!!!

You can have more than one type of combusting particle. Add a second type from the materials database or create your own. You probably need to work through some tutorials or check in the manual or do a bit of trial and error.
