Patent DE-3539956-A1 (DE)
Title: Process and unit for the gasification of combustible material
Inventor: LINNEBORN JOHANNES DIPL ING
IPC: C10J3/12
Filed: 1985-11-11
Abstract: The invention relates to a process for the gasification of solid and combustible material and to a unit for performing this process. Material to be gasified is to be understood as material in small particles, such as ground fossil coal and any organic materials, such as water, straw, husks and shells peel of fruits, to which sewage sludge can be admixed. The novel feature of the invention is that the gasification takes place in a dynamic, i.e. moving, bed which consists of preferably spherical, substantially abrasion-resistant bodies which are inert to the process taking place, the bed being brought to a temperature of about 1000 DEG C and maintained thereat during the process. This dynamic bed achieves rapid gasification of the material, and if sufficient H2O is fed to the process a CO-H2-CO2 gas mixture is obtained. According to the invention, the novel process can be performed in a closed channel (duct) which is agitated by vibration or shaking; the material, and the resulting ash, by virtue of the directional vibration passes through the channel from one end to the other and comes into contact continuously with spherical heat transfer bodies. This achieves rapid gasification of the material as a result of convection and radiation.
