[Stoves] New video from Tajikistan and Kyrgyzstan stove pilots

[Crispin Pemberton-Pigott]

Thanks Michael!

At the moment the engineer, Ulan, and team are preparing a producer’s manual and an installation manual. The latter is very interesting because they have worked out how to install these stoves (4 models) into a wide range of home types, in some cases where the existing product being removed is completely different in the way it fits into the building. Often the traditional stove is a structural element in a wall!

The fuels vary widely. In one region it is almost exclusively walnut! OMG. A lot of fruit wood is burned, a lot of dung for cooking and coal for heating (same stove). Cotton stalks are popular in that whole region. It is difficult to burn slowly.

There is a lot of new work going on. CARITAS Switzerland is working in Tajikistan (Jonas Haller) and he is just starting to produce 700 stoves for this season, two models 350 of each. We were collaborating on Skype to get the parts nested better and it is amazing how much better two heads work than one. Jonas is producing them in Muminabad in the deep south, one of the poorest regions of the poorest country in the former Soviet Union.

Dear Friends

The WB has put out a new combined video showing scenes from the two countries and it is available here<http://www.worldbank.org/en/news/video/2017/06/20/clean-individual-heating-solutions-in-the-kyrgyz-republic-and-tajikistan>.

The is a very brief shot of the gas flame at about 1:25. That is the Model 4 crossdraft coal gasifier flame. Note the colour. When the cover is on, it burns with less disturbance but that is hard to show without a glass cover.

There is also a good view towards the end of a TLUD gasifier which has a burn time of about 9 hours. The only fuel provided to schools is a very poor quality 'Aine coal' which is about 50% rock. It looks like black rock to start and white rock after burning. That TLUD is able to burn it properly provided there is sufficient draft, which means a 5m chimney. Achieving that was quite difficult, I admit and was only solve on literally the last day of the trip in November.

There are two videos now but I think the other one has been referenced here before. The new one is combined. A total of 91 homes were involved in the pilot in the two countries. The PM reduction numbers mentioned are modest, the true figures for the Models 4 and 5 coal stove are closer to 99.9%.
