Defining equivalence ratio for coal combustion
 

Hi

I am modelling coal combustion in ANSYS Fluent using EDM.

I have a question related to the equivalence ratio/stoicheometric ratio calculation when coal is present.

The formula for the volatile given in the coal calculator is C2.05 H4.50 O1.21 N0.0360 S0.0262. and my coal flowrate is 0.5 kg/s

The stoicheometric ratio I want to use is 1.18 for the air.

Is there a way to find how much flow rate should air be to maintain the Stoicheometric ratio to be 1.18
