Abstract: With the analysis of the industrial metabolism, this paper analyzes the energy metabolism of the coke production process in a coking plant, traces and analyzes the energy’s fluxion, clarifies the inputs and outputs of these energy flows for the enterprise to indentify the main energy loss units. It indicates that the efficiency of the coal-coke transformation is low, the cookery exhausts too much heat, the recycling rate of energy is low, and the wasting of all kinds of afterheat is comparatively serious. For instance, the coke cooling process uses wet-coke-cooling method; the afterheat of the red coke doesn’t get efficient recycling. The crude gas is cooled down by ammonia water spray, which leads to the great wastage of the crude gas’s afterheat. On the basis of the analysis, the paper gives advice about the optimization of energy system, reduces the energy consumption of per ton coke obviously, and gives the direction of energy-saving in coking industry.
