SHAFT-MELT GASIFIER AND A METHOD FOR THERMAL TREATMENT AND PROCESSING OF WASTE MATERIALS

摘要

The invention relates to a method for thermal treatment and processing of waste materials of various types, consistency and composition, such as pollutant-loaded waste wood, old tyres, industrial/commercial waste, domestic waste and bulk waste and a shaft-melt gasifier for carrying out said method. The above is achieved, whereby the waste material is introduced into the high temperature zone (H), directly after burning in the shaft-melt gasifier. The organic components contained in the waste material react with oxygen here. The reaction products are sucked into the furnace along with the residual waste materials in a co-current flow. The incompletely combusted organic components of the waste materials undergo a pyrolytic decomposition. Pyrolytic coke is formed, which is burned with oxygen in the reducing/cracking zone (Z) and the raw gas sucked off between the zones (11) and (7).
