PROCESS AND PLANT FOR THE THERMAL TREATMENT OF PARTICULATE SOLIDS, IN PARTICULAR FOR PRODUCING METAL OXIDE FROM METAL HYDROXIDE |
摘要 |
This invention relates to a process for producing e.g. anhydrous metal oxide from metal hydroxide, wherein the metal hydroxide is at least partly dehydrated and preheated, before the metal hydroxide is introduced into a fluidized-bed reactor (19), in which the metal hydroxide is heated to a temperature of about 650 to about 1250°C by combustion of fuel, and metal oxide is generated, wherein primary air and/or secondary air enriched with oxygen is supplied to the fluidized-bed reactor (19). To achieve a rather low dust emission and a small amount of grain disintegration, the oxygen or the gas enriched with oxygen is introduced into the fluidized-bed reactor (19) with a low gas velocity. |
