MOLTEN AND SOLIDIFIED INCINERATOR ASH MELTING AND SOLIDIFYING METHOD AND APPARATUS AND METHOD FOR USING MOLTEN AND SOLIDIFIED ASH

Title:

MOLTEN AND SOLIDIFIED INCINERATOR ASH MELTING AND SOLIDIFYING METHOD AND APPARATUS AND METHOD FOR USING MOLTEN AND SOLIDIFIED ASH

Document Type and Number:

Japanese Patent JP2002346502

Kind Code:

A

Abstract:

To provide a method and an apparatus to melt and solidify ashes capable of decreasing the volume of incinerator ashes by melting and solidification and detoxicating the ashes while saving auxiliary material cost and making the molten and solidified matter advantageously usable especially for an installation material in sea and to provide the molten and solidified matter and its utilization method.

Dried incinerator ashes are mixed with component adjustment materials of shellfish such as scallop, oyster and a reducing agent and melted in an electric furnace to discharge molten slag containing mainly SiO2, Al2O3, CaO, MgO, and the like, and the discharged molten slag is cast in a casting die and gradually cooled and crystallized to make it a rock with a prescribed shape and size. Based on the necessity, the obtained rock may contain mill scale as an iron ion donor.
