[Stoves] LPG import in India

Thu Dec 28 17:41:23 CST 2017

The odd thing about the 'Nigerian' source is that the EU requires that not only does it have to be from a sustainable source, it has to be produced using a method that yields 35% of the dry mass input.

As the stoves that I have heard about don't come close to that, it would perhaps be wise to start creating an argument holding that if a certain percentage of the initial energy was used for some useful (fuel displacing) task during the creating of the ‎charcoal, it counts towards the 35% mass yield. I suggest arguing for delivered energy for the task, worked backwards to a % of mass yield based on the efficiency and 29.5 MJ/kg.

In that way the efficiency of the application is encouraged to be high, and the system efficiency, even though displaced by thousands of miles, is assessed fairly.

Thoughts?

I would be interested to know what proportion of charcoal is imported
compared with locally, probably artisan made, but also proportionally for
what purpose charcoal is used in European countries generally.
Pharmaceuticals, food, air and water filters are some uses that come to
mind, but how do such sectors compare with leisure BBQ consumption?

In Britain reconstituted charcoal briquettes seem more popular, probably
because cheaper than 'lumpwood' charcoal which is much nicer.

We enjoy as many BBQs as we can, but I haven't bought any charcoal for
well over a decade, making our own entirely from the residue of TLUD
stoves used for cooking in the garden, rocket stoves and the occasional
outdoor fire in a bowl improvised from an old kettle BBQ with domed lid
that when placed over the fire at or near the end of pyrolysis, and the
vent sealed with some clay soil, liberates when cooled a bucket full of
charcoal for the BBQ.

We use a smallish pot bellied cast iron BBQ, but can't find them on US
ebay.  This link is for UK ebay:

With very fine char such as the TLUDs produce, I re-use the mesh
scavenged from other peoples discarded disposable BBQ trays doubled up
across the grate to retain the fines.  Lit with a couple of sheets of
newspaper, and an old computer fan to augment the draft, we are cooking
in under a minute of striking the match.

I would like to see more clean biomass stoves available at more
affordable prices in the UK such as Dr Nurhuda's Prime stoves or the Fyro
stove when developed, as I am sure there is a much larger potential
market for outdoor wood and charcoal fired kitchens than is currently
exploited, and char making for the BBQ could become an easy option as
part of that.

Hope the above is sufficiently descriptive to be interesting.
