Stovers,
I am encouraged by the prospect of using the standard "holey briquette"
plus the use of charcoal as "space filler" that I wrote about just a few
minutes ago. With the right size of TLUD fuel chamber (about 1 or 2
inch diameter larger than the diameter of the fuel briquette inserted
vertically), with some charcoal as space filler and in the central hole,
it might be excellent.
Needs to be tried.

Of course, the preferred choice is to use pellets in stoves, but for
some people, pellets could be a bit expensive. Briquettes look like a
good compromise between uncompressed crop residues and pellets, if
they can be made using low-cost equipment that doesn't require
electricity.
What is the experience of stove researchers with briquettes? Do they
burn cleanly and efficiency in TLUD stoves? Are they a bit bulky for
cookstoves? Do they make biochar, or do they turn to ash as they burn
in from the outside?
The briquetting is Richard's bag and I expect he will reply. To say
that pellets "could be a bit expensive" is an understatement for those
people that the Legacy Foundation teaches how to utilise crop residues
as a cooking fuel. Essentially the process is a bit like making
papiere mache from residues that has started to decompose, the fibres
separate and then mesh together in a simple wet press. Other wastes
like sawdust and charcoal fines can be entrained in the mesh of fibres
to bulk the briquette and often in crease the energy content. They
then dry in the sun.
Yes they do burn TLUD

Have a search on Kobus Ventner and Rok Oblak at this site as they have
a wealth of experience making briquette burning stoves.
