[Stoves] Interesting TLUD application

Crispin,

Thank you for that link.   But please note that it is from2010, back when BP
was still funding the Oorja stove efforts.   I have not seen any recent data
about the Oorja stoves.   And the website for      firstenergy.in     is not
responding.

Dear Paul

One of the related referenced open source articles is

https://www.researchgate.net/publication/242588697_Gasifier_stoves_Science_t
echnology_and_field_outreach

Abstract

Development of a new class of single pan high efficiency, low emission
stoves, named gasifier stoves, that promise constant power that can be
controlled using any solid biomass fuel in the form of pellets is reported
here. These stoves use battery-run fan-based air supply for gasification
(primary air) and for combustion (secondary air). Design with the correct
secondary air flow ensures near-stoichiometric combustion that allows
attainment of peak combustion temperatures with accompanying high water
boiling efficiencies (up to 50% for vessels of practical relevance) and very
low emissions (of carbon monoxide, particulate matter and oxides of
nitrogen). The use of high density agro-residue based pellets or coconut
shell pieces ensures operational duration of about an hour or more at power
levels of 3 kWth (~12 g/min). The principles involved and the optimization
aspects of the design are outlined. The dependence of efficiency and
emissions on the design parameters are described. The field imperatives that
drive the choice of the rechargeable battery source and the fan are brought
out. The implications of developments of Oorja-Plus and Oorja-Super stoves
to the domestic cooking scenario of India are briefly discussed. The process
development, testing and internal qualification tasks were undertaken by
Indian Institute of Science. Product development and the fuel pellet
production were dealt with by First Energy Private Ltd. Close interaction at
several times during this period has helped progress the project from the
laboratory to large scale commercial operation. At this time, over four
hundred thousand stoves and 30 kilotonnes fuel have been sold in four states
in India.

Regards

Crispin

I thank David Lello (of South Africa) for finding this 2011 document.
(maybe other had seen it before?)

Nice work from the Balkans.   I wonder if they have continued and what
progress might have been made.   Be sure to seen the "References" which name
other unknown (to me) publications.

REQUEST:   Would someone volunteer to track down the authors to find out
about further work?

Paul
