Dear Anil The very simplest way is to get one of the suction pumps that have a small round filter over the inlet. The unit sucks in 'smoke' at a rate of about 100 cc per stroke. You can then pull in about 20 strokes and then use a comparison chart (or just compare the filters) to see how brown/black they are.
It is very simple. I can't recall who makes them but GTZ in Harare had one which REASWA used in a test of indoor air in Swaziland in....maybe 2004. Because you can do it periodically during the burn, you can get a feeling for how things are going. If you put the stove on a scale you can get a general relationship between mass burned and the blackening of a number of little filters. At the very least you can make a comparison between stoves, or settings on a single stove. What Tami Bond has (rather cleverly) done is to take a smoke detector and run it well beyond its design limit with some added electronics. I believe it costs about $150 to create what is then a simple particle detector with meaningful accuracy. Then you add a fan. Perhaps she has the best solution around for a low cost continuous measurement. I am sure she would share the details. Her students were building them a couple of years ago. They are the size and shape of a home smoke detector because that is what is inside it. Regards Crispin ++++++++ Hello stovers, Is there a simple method of measuring particulates emissions from a kerosene stove or lanterns? Your help will be greatly appreciated. Cheers.
