[Stoves] Cleanest Stove Ever?

[Leslie Cordes]

Crispin, we have not heard many reports of people having trouble getting visas, as you report below, but our team is available to help if that is the case, as some participants may still be able to get visas on arrival.  Please go to the Forum website www.cleancooking2015.org<http://www.cleancooking2015.org> and click on hotels and visas for more information.  If you or your colleagues are still having trouble, kindly send an email to forum at cleancookstoves.org<mailto:forum at cleancookstoves.org> and we will try and help.

Thanks,

Leslie

Dear Paul

I knew that would get your attention. I will do my best to get one. The project requirements do not include a minimum turn down ratio, though it is recorded. We do not interfere in the market or the social acceptance criteria, just test things.

I don't even know the name of the producer. The power is low, the control modest. More important for everyone is how it works and why it does what it does. I would still be quite happy if it turns out the 'real emissions' are five times what these tests say it it, it will still be comparable with LPG.

Now let's revisit the statement that people need clean cooking solutions because they have traditionally been forced to cook using 'solid fuels'. There is nothing inherent in all solid fuels? that prevents then from being burned cleanly.

The very best lignite burning stoves seen in Mongolia literally strip the PM out of the air by burning ambient particles while producing none themselves. That is another ?example of 'competing with gas'.

It is also worth noting that such stoves cook with less total PM than a power station supplying electricity because of transmission and combustion inefficiencies. That is a repeat of the space heating stove performance which cross that threshold at least five years ago.

I am not sure who will make it to Ghana. There are many reports of people having trouble getting a visa and tickets. I have the former but yet not the latter. ?China may not make it. I know someone who has a ticket but no visa. I am on the road. It is not possible to get a visa when travelling.

I'll see you if I can.

Crispin and all,

That is indeed wonderful news for eventually solving the health problems world-wide concerning Household Air Pollution (HAP)!!!!!!!!!!!!

Accomplishing that with NATURAL DRAFT is doubly exciting!!!

The stove was capable of doing that cooking test.   We await information about its power level(s) and turn-down ratio, both of which are important but truly secondary to the low emissions and high efficiency capabilities.

Looking forward to seeing the stove in Accra.   A biomass stove that is "Tier 4" in all categories by the end of 2015 will do wonders for accomplishing the GACC goal of 100 million CLEAN cookstoves by 2020.

In Accra I and others will have good news (and functioning units) relating to forced air TLUDs with configurations suitable for mass production utilizing industrial capabilities that are already existent in numerous developing countries.   And using a variety of biomass types and shapes.

I will be in Ghana from 1 through 14 November, and looking for contacts with all who are interested.

Dear Friends of Clean Combustion

The second call for technology proposals for the CSI-Indonesia is concluding with an announcement of test results to be made this coming week. I can't mention names but I wanted the TLUD community and stovers in general to be aware that one of the submissions is more than interesting.

It is a TLUD charcoal maker that tested three times with a PM emission for the Central Java combination cooking cycle (the Technical Test) of just 2 mg/MJ delivered. This is about 1/4 of the PM from an LPG stove (as tested in India) and 1/10th of the emissions of a Philips fan stove burning pellets. Being somewhat suspicious because the test results could be accidentally that low three times in a row, it was repeated with great care to see nothing could possibly interfere with the result and the 4th test was substantially the same as the first three, except for a lower CO value <1 g/MJ delivered into the pot.

The system efficiency is in the high 30's. The test method assumes char produced cannot be reused (see the test method online). The energy efficiency is much higher.

This small, inexpensive natural draft product show?s that solid fuels (Albasia pellets with 5.6% moisture in this case) can burn cleaner than LPG and natural gas if the fuel is predictable and standardised.

The cost of standardising sustainable wood pellets is much less than the cost of introducing ?LPG, electricity or other liquid fuels. The result should of course be confirmed in other labs because it is running on the limits of detection and quantification wherever it is tested. If these results can be confirmed it throws down the gauntlet to the producers of other stoves that burn ethanol, DME, methanol and LPG to improve their product performance to match both this wood pellet burner and the very clean lignite burning stoves in Mongolia.

Let's give them a round of applause in Ghana when the product is identified. I will try to obtain one this week to bring to Accra.

Best regards
Crispin
