Document Type and Number:
WIPO Patent Application WO/2019/142814
Kind Code:
A1
Abstract:
The present invention provides a useful fluidized medium for a fluidized bed, the fluidized medium having excellent fluidity and being suitable for use as a fluidized medium in a fluidized bed furnace that uses biomass material and coal as fuel. The present invention also provides a useful fluidized medium for a fluidized bed, the fluidized medium having excellent durability, not easily forming an aggregate of particles, and not being easily destroyed. Used as the fluidized medium for a fluidized bed in a fluidized bed furnace that is used to combust or gasify fuel comprising biomass material and/or coal is a fluidized medium that comprises artificially produced spherical refractory particles having a chemical composition comprising 40 wt% or more of Al2O3 and 60 wt% or less of SiO2, having an apparent porosity of 5% or less, and having a weight ratio of 20% or less of aggregated particles after a heating treatment test has been repeated three times at 900ºC×2 hours in coexistence with the fuel.
