Abstract
PURPOSE: To obtain a char suitable for a raw material of metallurgical coke form a highly volatile non or slightly caking coal, by controlling the temperature and time of an external heating gas in the outer heat transmitting wall of an oven chamber according to the predetermined pattern.
CONSTITUTION: An external heating shaft furnace is used as a preliminary dry distillation apparatus. If the preliminary dry distillation apparatus is a chamber oven, the temperature of a heating gas in the outer heat transmitting wall of the chamber oven in the preheating dry distillation apparatus and time are controlled according to the predetermined pattern. The temperature is controlled suitably from the initial temperature of about 250°C to the final temperature of 450W600°C. The raw material coal near the heat transmitting wall and that in the center of the chamber oven are heated at the same heating rate to permit the slow dry distillation with ready recovery of by-products (volatile contents).
