Coal particles at outlet
 

Hi all,
am doing a coal combustion simulation in CFX13 in Burner.My coal is 42% ash and 58% raw combustible.
after convergence i checked the out file for particle summary.It gives some X (100%) mass flow rate at inlet and Y (48%) at outlet.
Now i have a doubt on this.whether this includes ash mass fraction also or the unburned carbon particles alone.Please clarify me.

thanks in advance
