Latest Patents
Johannes Arnhold holds a patent for a process for making wood charcoal. This innovative method involves carbonizing lump wood in a shaft retort, which is flown through by hot rinse gas. The wood is charged to the retort at its top, while wood charcoal is withdrawn from the lower portion of the retort. The exhaust gas produced during carbonization is withdrawn from the top end of the shaft retort and is directly fed to a combustion chamber. In the first section of the combustion chamber, the exhaust gas is combusted with air at a rate that varies from understoichiometric to stoichiometric, at temperatures ranging from 800°C to 1250°C. Part of the combustion gas is then cooled and fed back as rinse gas to the shaft retort. The second section of the combustion chamber ensures complete combustion of the exhaust gas with air supplied at an overstoichiometric rate.
