Regular Wood Stoves
Experts such as Dr TLUD, Thomas Reed and Paul Wever say the distinguishing characteristic of “true gasiﬁers is that the creation of the gases (“smoke”) is separate from where the gases are combusted. Of crucial importance in these (and in any stove) are the ﬂows of primary and secondary air. In the gasiﬁers, the ﬂows are separate. In most regular wood stoves, they are mixed”. Regular wood stoves like those below are much more efficient and safer than cooking on open fires, but they aren’t gasifier stoves.
EcoZoom Stoves by Vuthisa Technologies in South Africa. The Stoves burn cleaner, use less fuel, and are more economical than many other stoves. It’s based on the rocket stove design principle, invented by Dr. Larry Winiarski from Aprovecho Research Center (ARC) USA. The original StoveTec range of stoves was launched in 2008 and Aprovecho won the prestigious Ashden International Energy Champion Award for 2009. They have disseminated over 70,000 stoves to impoverished communities in the last year and have a production capacity of 500,000 per year. The first StoveTec stoves arrived on the market in 2008 and they are all still going strong. The stove can be used with a variety of fuel types in addition to wood including dried corn cobs, grass, roots, dung or any other readily available biomass.
