PROCEDIMIENTO CON SU DISPOSITIVO CORRESPONDIENTE PARA LA DESECACION Y EL PRECALENTAMIENTO DE CARBON DE COQUE EN UN MISMO TUBO DE CORRIENTE VOLANTE

摘要

Method dries and pre-heats coking coal in a single pipe, in which a current of hot gas transports the damp pulverised coal fed in at the bottom upwards. At the top of the pipe the dried and preheated coal is sepd. from the current, the coarser particles being sepd. at a point in the pipe and returned to the part contg. the finer ones. - The gas current is divided into two parts, the larger one being deflected from the original direction and taking the finer particles with it. The smaller one continues initially in the original direction with the coarser particles, after which it is deflected and returned to the first again but in the opposite direction.
