METHOD OF DISPOSING OF SALT-CONTAINING DUSTS FROM INCINERATOR PLANTS

摘要

For the disposal of salt-containing dusts of incinerator plants, the salt-containing dusts are intensively mixed with water and other waste materials. The other waste materials include ashes and fly ashes from thermal power plants fired with hard coal or brown coal, waste materials from foundries containing quartz sands and waste materials from calcium carbide production. The mixture contains at least 8% hydrothermally reactive calcium oxide or equivalent amounts of other hydrothermally reactive calcium compounds, and the water addition is such that an optimum compacting is possible. The mixture is thereafter processed by compacting to give stable firm compacts, and the compacts subsequently hardened in an autoclave by saturated steam at a pressure of at least 1 bar.
