Description of key information
The granulometry was measured for Fly Ash and Bottom Ash separately because it is collected in different ways due to character of particles.
The sieving method was used for the particle size distribution of the test substance, Fluidized Bed Combustion (FBC) Bottom Ash.
The laser diffraction method was used for the determination of the particle size distribution of the test substance, Fluidized Bed Combustion (FBC) Fly Ash.
Additional information
Size of individual particles of (FBC) Ashes is quite different – structure of (FBC) Fly Ash is rather fine whereas structure of (FBC) Bottom Ash is coarse. In (FBC) Fly Ash more than 90% particles are smaller than 0.074 mm and in (FBC) Bottom Ash more than 94% particles are smaller than 1.00 mm and only 2,4% of its particles are smaller than 0.08 mm.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
