Thermal behavior of biomass under thermochemical treatment at different air fluxes in an updraft reactor

Thermochemical treatment was investigated experimentally at different air fluxes in an updraft reactor. The test rig equipped with a special attached door that will open specific time step. This unique feature allows investigators to obtain information on the packed bed color variation along heights of reactor evolves points time. analysis focused temperature dynamics obtained from installed thermocouples each investigation conducted for three supply mass fluxes, which were 670, 480, and 190 kg/m2h. general thermal behavior is addressed first part paper because it similar all input fluxes. Next, distinctive operation parameters among are discussed; these included hot spot zone, fuel conversion characteristic, distribution, heat transfer, kinetic activities height
