Abstract:

A mathematical model is established for the existing problems of the gooseneck and gas collecting main of a coke oven with heat recovery. The flow heat transfer in them is analyzed and studied by the utilization of the CFD numerical simulation software. The result shows that under the conditions of the fixed dimensions and good thermal insulation performance of the branch pipes of gas collecting main, it is as much as possible to increase the branch pipe diameters of the collecting main to balance the suction force of coking chambers to corresponding gooseneck and thus to increase the volumetric flow rate of flue gas from coking chamber at the end of branch pipe of the collecting main.
