Modelling Burner Combustion in a Reactor Network - How to integrate a PFR? (in Python)

[T Berry]

Hi everyone,

I am trying to model the combustion of methane in a shell boiler. I have successfully modeled the combustion using the combustor.py example initially (I thought this to be more suitable than the flame examples as I can input fuel and air separately). I have then added a re-circulation from exhaust back into flame to model the recirculation zones in the furnace (10%).

MY QUESTION is how can I add a plug flow reactor (PFR) onto the exhaust reservoir in order to model the post flame zone, where the rest of the CO is oxidised and NOx continues to be formed. 

I have tried using the FlowReactor, however this cannot be used with other reactors and I have tried incorporating the PFR model in surf_pfr.py, however I cannot figure out which bits I need to include as its modeled around a catalyst surface.

Please find code attached.

Please note: I'm very new to cantera and python, and only just getting used to the way the language works.

Many thanks

Tom

Dear Tom,

During my PhD I used extensively Cantera for several purposes, including the simulation of  PFR in homogeneous media.
I adapted the example from surface_pfr.py into a class which you may find in my scripts stored at
https://github.com/waltermateriais/xutils/blob/master/xpython/xchemistry/xcantera/flowreactor.py

Please notice that this script uses some functions of my personal package "xutils" and are not fully documented yet. Please find attached an example application as I used in my thesis (I tried to comment, read the code above or contact me for additional details/suggestions). As soon as I pass my defense I will document the whole package and 'tell the community' about its existence. I checked that the current version under development of Cantera will be issued with a advance_to_steady_state function, which will simplify my routine.

This thread is long time ago. I can't find any code from github. I wonder if Walter can share it again?!

Best,
