It would be useful for someone in Chennai to connect with Duraisamy
Sakthivadivel to see how this group  at Guindy Campus, Anna University might
help move fan stove development and use forward. As background, in 2013
professor P Raman and his group  published an "Evaluation of Domestic
Cookstove Technologies Implemented across the World to Identify Possible
Options for Clean and Efficient Cooking Solutions". http://bit.ly/2l0uDF1

In addition to the paper I previously mentioned they recently (Feb 14, 2017)
published:

Abstract

The drastic hype in fuel consumption and oil price hike in world market,
people around the world intended to move towards the alternative source of
energy like biomass for cooking. Many cook stove programmes were implemented
in the world aiming to reduce the fuel consumption as well as pollutants
through improved biomass cook stoves. Many improved cook stoves have the
maximum efficiency with higher level of fuel consumption due to its higher
burning rate. In this paper an attempt has been made to improve the thermal
efficiency by reducing heat losses mean time in reduced specific fuel
consumption. The pollutants emitted by the improved stove is extremely
reduced by proper supply of air for combustion. Since advanced cook stove is
made to operate at different geographical region, should be harmonious to
the use of different fuels. The newly developed ACS IES-15 stove is tested
with coconut shell and the result is compared with existing (TERI SPT-0610)
stove commercially available in the market at higher thermal efficiency
(37%). Testing procedure is followed as per the world standard testing
protocol WBT 4.2.3 to evaluate the performance of these stoves and analysed
in terms of efficiency and specific fuel consumption.

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_o
f_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.   

Paul

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?
