Electrical Power Generation from Heat Recovered at the Throat of a Downdraft Biomass Gasifier
Nzihou Jean Fidele1, *, Hamidou Salou2 , Imbga Kossi1 , Segda Bila Gerard3 , Ouattara Frederic1 , Tiemtore Hamadou1
: Gasification, a thermochemical process that takes place in gasifiers, is now understood as a process of transforming
the solid components of biomass into combustible gases essentially consisting of carbon monoxide (CO) and dihydrogen (H2).
This technology is relatively old and was widely used during the Second World War to deal with the(...)

Experimental Study of the Evolution of Temperatures in Pavement Structures and Influence of Traffic on the RN1 in Burkina Faso in a Hot and Dry Climate
Paul Ilboudo, Boubacar Soro, Dieudonné Dabilgou, Boureima Kaboré, Jean Marie Compaoré, Sié Kam, Dieudonné Joseph Bathiebo
Asphalt concrete pavements in hot and dry climates deteriorate prematurely some time after their construction. This degradation is accelerated under the effect of heavy vehicle traffic pressure and high temperatures after the bitumen has softened. A study was conducted on the RN1 in Burkina Faso in order to analyze the evolution of temperatu(...)
