" It is unfortunate that people produce stoves that have chimneys, but are not actually clean-burning." Do we actually have chimney stoves that do not clog up after few months/years? Even the cleanest stoves? Is it a good idea to build chimney stoves at all?
"Your grate price is good! I think we should be jealous! It would be so nice to be able to get good parts in cast iron." Hell yes, I can make 1 dollar iron grates, but I wish we could make 1 dollar cast iron grates in Benin. In fact, cast iron is very rare in Benin (West Africa? Africa?). When Africa will have the industrial production capacities of Asia, things will change! -----Original Message----- Message: 4 Date: Tue, 7 Feb 2012 00:14:57 -0500 From: "Crispin Pemberton-Pigott" <[email protected]> To: "'Discussion of biomass cooking stoves'" <[email protected]> Subject: Re: [Stoves] advice for chimney wood stove for rural Burkina Faso Message-ID: <[email protected]> Content-Type: text/plain; charset="us-ascii" Dear AD Your story is not very unusual. It is unfortunate that people produce stoves that have chimneys, but are not actually clean-burning. My point is that just because one produces a chimney stove is no excuse not to use that additional expense to create the draft needed to completely burn the fuel. Astonishing really. I wonder if there is too much emphasis on 'clean indoor air' without enough emphasis on 'not needing to worry about clean indoor air' in the first place. That level of deposition is depressing. I heard about a stove being produced in the tea country high in Kenya which is used for space heating and cooking, According to the designer the 3 inch chimney would clog after three months. That is ridiculous! What kind of crummy combustion is that? A chimney is as good as a fan - especially 3.5 metres. Fan stoves are supposed to be really clean or you have not done a good job. Shoving bad combustion outside does not solve much. The situation in Ulaanbaatar is exactly like that. No one has a stove without a chimney. The air outside is so polluted that it is contaminating the air drawn into the homes. So the chimney solved nothing - the problem is the stove. Your grate price is good! I think we should be jealous! It would be so nice to be able to get good parts in cast iron.
