METHOD AND APPARATUS FOR CONVEYING AND/OR HEATING COAL PARTICLES IN A DENSE PHASE FLOW

摘要

ABSTRACT OF THE DISCLOSUREAn improvement in a method and apparatus forconveying and/or heating coal particles in a dense phaseflow through transfer lines wherein the velocity of theflow through the lines is controlled by a progressiveenlargement of line size during indirect heating and/ortransfer in the lines thereby minimizing erosion of thetransfer lines by the coal particles.
