Process for the simultaneous melting of powdery materials and lump slags from refuse incinerating installations.

摘要

The process is for the simultaneous melting of dust and coarse slag from refuse burning plants in a closed electric furnace. The melt is covered by a layer of coke. At least one electrode dips into the melt. Dust is introduced to the melt through a hollow electrode or lance. Slag is fed above the melt through a tube. Melting under reducing conditions is achieved by the addn. of carbon in the dust and slag feed, the proportions being such that the resultant prod. meets the potable water-Trink V specifications. Also claimed is the installation for achieving this.
