Title: Jorg Schmalfeld: Innovator in Wood Charcoal Production
Introduction
Jorg Schmalfeld is a notable inventor based in Friedrichsdorf, Germany. He has made significant contributions to the field of biomass processing, particularly in the production of wood charcoal. With a total of 3 patents to his name, Schmalfeld's work showcases innovative methods that enhance efficiency and sustainability in charcoal production.
Latest Patents
Schmalfeld's latest patents include a process for producing wood charcoal in a moving bed. In this method, biomass, especially lump wood, is introduced into a shaft reactor where it is preheated to temperatures ranging from 150 to 280 degrees Celsius. The wood undergoes drying through a counterflowing hot gas before being treated in a carbonizing zone. This zone is supplied with hot purging gas at temperatures between 250 and 600 degrees Celsius, allowing for effective carbonization. A gas mixture, which includes both purging gas and gas produced by carbonization, is extracted from the lower part of the carbonizing zone and partially combusted outside the reactor to generate combustion gas, which is reused as hot purging gas.
Another significant patent involves a process for making wood charcoal in a shaft retort. In this process, lump wood is carbonized while being flowed through by hot rinse gas. The wood is charged at the top of the retort, and charcoal is withdrawn from the bottom. The exhaust gas produced during carbonization is directed to a combustion chamber, where it is combusted with air at controlled rates and temperatures. This innovative approach not only improves the efficiency of charcoal production but also enhances the overall sustainability of the process.
