The use of fossil and nuclear energy is at the root of global warming and the risks associated with nuclear accidents. This is why many researchers and scientists have started looking for ways and means to significantly reduce the use of these forms of energy. Thus renewable sources including solar, biomass etc ... have reduced the use of fossil sources. But in many cities, the use of wood for fuel and charcoal is behind the advance of the desert and deforestation. One way to significantly reduce the use of wood and the preservation of flora the use of improved stoves. These homes reduce the consumption of wood and charcoal in households. In Togo, the conical hearth is one of the best that saves coal more than 30% [1] compared to the “Malgache” stoves. In this work, we introduced clay into the UB conical focus to further improve its performance. The results of the study are interesting and allow us to conclude that the introduction of clay has saved coal at 28% compared to the original conical focus given the properties of the clay. Thus the extension of this new home in Togo and the sub-region will contribute to the reduction of greenhouse gases, reduce deforestation and reduce the progress of the desert in the world.
