It was found that coal dust occurs when coal is charged into a coke oven chamber and that such coal dust significantly influences the rate of carbon deposition from coal carbonization gas. There-fore, a laboratory experiment was conducted to quantitatively grasp the behavior of coal dust generation. Namely, using four types of
