Hi All,
I am trying to model pure coal combustion in Fluent but I do not know how to calculate Volatile Molecular Weight (Kg/Kmol) using Proximate and Ultimate Analysis. I can calculate mass fraction of C, H, O and N in volatile but I do not know how to use them to get x,y,z and w in CxHyOzNw. Do you have any idea to help me out? Thanks |

Hi,
Molecular Weight of compound can be computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together. |

Thanks, but the problem is that I do not know the chemical formula and I'm looking for a way to find it. Let me clarify my case: I have 35.61 gr of volatile which is composes of C, H, N, O and S. I know the fraction of each substance as 20.22 gr of C, 4.77 gr of H, 1.54 gr of N, 7.78 gr of O and 1.3 gr of S. Now, I want to know the molecular weight of my volatile or in other word the coefficients of CxHyNpOqSr. Any idea?

Old post but who knows right?
Take a look at this topic from this work, very good one. Alganash, Blaid Sasi Abozeid (2015) Numerical investigation of the combustion processes of various combustion regimes. PhD thesis. |
