BIOMASS ASH MODIFICATION METHOD, SYSTEM FOR CONVERTING BIOMASS ASH INTO CEMENT STARTING MATERIAL, AND MODIFIED BIOMASS ASH

WIPO Patent Application WO/2021/193668

A1

The purpose of the present invention is to surely convert a biomass ash into resources. For this purpose, provided are a biomass ash modification method and a system for converting a biomass ash into a cement starting material. Also provided is a modified biomass ash having good qualities. The biomass ash modification method is characterized by comprising a slurrying step for adding water to a biomass ash to give a slurry, a water washing step for washing the slurry with water, and a dehydration step for dehydrating the water-washed slurry. The system for converting a biomass ash into a cement starting material is characterized by comprising a powder dissolving tank for adding water to a biomass ash accommodated therein to give a slurry and then washing the slurry with water, a solid/liquid separation device for dehydrating the slurry discharged from the powder dissolving tank, and a carrier device for carrying the dehydrated matter separated by the solid/liquid separation device to a cement production facility. The modified biomass ash can be produced by the method or system described above.
