Investigation of char structures from CFB-combustion of a bituminous coal; Undersoekningar av ett bituminoest kols charstruktur fraan foerbraenning i cirkulerande fluidbaedd

Abstract

Structural changes from coal to bag filter ash have been studied for a bituminous coal combusted in a 2.5 MW CFB. The behaviour from coal through various recirculating chars has been investigated. This project have been carried out in cooperation with STUDSVIK Energy. Already after a very short residence time at 850 deg C vitritic components had swelled to a porous anisotropic coke. The coke structures were considerably thicker than fusite structures. Coke structures reduced thickness considerably slower than the fusite structures explaining unexpected good burn out properties for inertinite in CFB-combustion.
