Coking. Coking is the heating of coal in the absence of oxygen to a temperature above 600 °C to drive off the volatile components of the raw coal, leaving a hard, strong, porous material of high carbon content called coke. Coke consists almost entirely of hydrocarbons. The porosity gives it a high surface area, which makes it burn faster (as ...

The charged coal is heated through the two side walls, so the coal nearest to the walls is heated rapidly and transformed into coke. During the process, the heat that is supplied from gasburning flues located within the walls of each oven is gradually transmitted from the hot brick walls toward the center of the oven charge (Fig. ).
