The coal loading is insufficient, resulting in large space at the top of the furnace and high temperatures in that area; this leads to secondary cracking of the gas, generating a large amount of free carbon. The viscosity of tar increases. The control method is to load the furnace with coal to full capacity and maintain an appropriate temperature in the furnace roof area.
