[Stoves] Help: What areas can I work on stoves in terms of fuels and combustion?

[Chikere Okorafor]

Good day House,
I am running a Masters programme in Thermofluids and Power Plant
option at Federal University of Technology, Minna, Nigeria.
I am also working on improving and reducing the production cost of a
wood stove (AUTOCAD design attached) but confined to Combustion
analysis and fuels used.

What areas can I work on in terms of fuels and combustion analysis?
Contributions are highly welcome.
Thank you
