METHOD OF CARBONIZATION USING SCREW TYPE CARBONIZING FURNACE

摘要

PROBLEM TO BE SOLVED: To provide a method of carbonization using a screw type carbonizing furnace capable of keeping up quality of products constant, downsizing apparatus by improving performance of the carbonizing furnace. SOLUTION: This method heats and carbonizes the material to be carbonated while conveying in plural screw conveyers 3, 4, 5, 6 each having a jet exhaust for carbonizing gas installed approximately horizontal in a heating chamber 2, the conveying speed of the screw conveyers are controlled according to the measured temperature of the carbonized material exhausted from at least the final step or its prior step screw conveyer by measuring the temperature of the prescribed carbonized material.
