Mv volatiles
 

I try the modeling of combustion with injection. My fuel is coal-mv and i use some information from a tutorial for the reactions in the tab of materials. My problem is that i can't define the composition of mv volatiles(in this tutorial in the tab of reactions in materials it is used 6 reactions which include c<s>, co, co2, h2, o2 and a chemical formula named mv_vol). i dont know which species i use in this chemical formula mv_vol and so the composition of this mv_vol. can anyone help me?

also i try to find in which tab i can define the heating value of my fuel. thank you
