Improvement in the transportation process of coal particles in dense phase flow through a transfer line; and the set of transport of particles of coal in a dense phase

摘要

An improvement in a method and apparatus for conveying and/or heating coal particles in a dense phase flow through transfer lines wherein the velocity of the flow through the lines is controlled by a progressive enlargement of line size during indirect heating and/or transfer in the lines thereby minimizing erosion of the transfer lines by the coal particles.
