METHOD OF MANUFACTURING HIGHLY SOLUBLE SILICEOUS FERTILIZER FROM HUSK INCINERATION ASH

摘要

PROBLEM TO BE SOLVED: To effectively utilize husk by converting husk ash produced by the incineration using the husk that is carbon neutral biomass produced in a large quantity as a heat energy source into a highly valuable material as an industrial raw material. SOLUTION: In the method of manufacturing the highly soluble siliceous fertilizer from the husk incineration ash, porous activated siliceous ash which is free from the incorporation of clinker grains produced by local high temperature and keeps fine structure peculiar to the husk is obtained by adjusting the atmospheric temperature to 450-800°C in an incineration furnace and controlling the firing condition such as the quantity of air or the temperature of the ash in the incineration of the husk in the furnace.
