The carbon adhered to the coke oven wall can be classified into "primary" and "secondary" ones, the former being laminar parallel to the wall, and the latter granuler with less content of ash.<BR>By employing a test oven with 8kg coal charge, the factors that influence rate of carbon growth were studied.<BR>Rate of growth is influenced by the temperature of adhesion surface, coal volatile matter and moisture, and expressed by following formula.<BR>D (mm/day) =64.5<I>e</I>-7.95×10<SUP>3</SUP>/T (°K) ·VM (%) [1-0.0476W (%)]<BR>Where D, T, VM and W denote rate of growth, temperature of adhesion surface, volatile matter and moisture respectively.<BR>By using this formula, at the space temperature of 800°C for a charge with 30% volatile matter and 10% moisture, the rate of growth was found to be 0.6mm per day, which is nearly much of result by notych and value observed usually at coke oven.
