[Stoves] Re: Combustion characteristics of biomass fuels in a fixed bed micro-gasifier cook stove


Stovers,

With thanks to Tom  Miles.  He sent

This was a prior (2015) paper by the same author as the recent citation from Anna University in Chennai.

https://www.researchgate.net/publication/283092306_Experimental_evaluation_of_a_forced_draft_micro_gasifier_cook_stove_using_juliflora_wood_and_coconut_shell

Key from that publication is the list of 3 stoves tested:   Oorja, TERI SPT-0610, and Eco Chulha (by Abellon).  You can search the internet for each and see photos and info. 

What they all have in common is FA (forced air or fan assisted).   In basic TLUD configuration (or some fan-jet approach?).   Especially the Oorja encourages the “char-mode” after any migratory pyrolytic front (MFP) has finished.  

The “char mode” is KNOWN to burn out the guts of these stoves, but these stoves are still in use and are reserched with respectable budgets and probably awarding  of academic degrees.

I suspect that few such researchers read the Stoves Listserv.   Sort of like reinventing a wheel that is not round.

No further comments at this time.

Tom and Stovers,

Thanks for that reference and abstract.

I am not going to pay about US$40 to read it, but when someone does, please send comments to the Stoves Listserv.   I am particularly interested in the

The two mode operations of combustion processes namely flaming and char mode of the fuels were also studied.

“Char mode”.   Interesting.   Burning char in a TLUD is not good practice for cooking, but maybe the laboratory scientists want to learn about something that is sub-optimal for cooking and shortens the life of the stove.  This is all too common in the “peer reviewed” publications:  Out of touch with the real-world applications of micro-gasifiers.

But maybe it is not a TLUD????   “fixed bed micro-gasifier stove” might be something else?    Or do the researchers choose to ignore body of literature with TLUD mentioned??    The list of references (seen at the provided link) certainly avoid any document with TLUD in its name, but did include the first edition (2011) of Christa Roth’s major book.

This is just the abstract but how do these results compare with tests of similar stoves? How would other, or additional, tests that have been mentioned in the last few months change the results or use of the data?
