| 摘要 |
A process and installation for the production of powdered, surface-active, agglomeratable, calcined material, specifically calcined lime, from a material or raw material present in the form of sludge, scum or the like such as the waste materials in the sugar industry. One specific example of the process is production of calcined lime and/or usable CO2 from waste materials existing in the sugar producing industry. The installation in which the process is carried out includes a special calcining or reaction chamber which provides parallel flow paths with a turbulent vortex zone within which the raw materials are subjected for controlled periods to desired reaction temperatures.
