Non-premixed/Coal/2 oxygen inlets
 

Hi everyone!

I have a problem with the modeling of my furnace. I want to use a PDF table to model my coal combustion. So I use the Non-Premixed combustion model. I use the DPM, and my devolalization model is the single rate model.

I have two inlets of oxygen with different compositions and I don't know which inputs I have to choose.
I tried to put a secondary stream, in order to define my both oxidizer stream with right parameters, but the calcul failed when a DPM iteration come.

Could you help me with this problem, please?

Thank you very much

(and please, excuse me for mistakes :))
