Although the total amount of coal resources in China ranks number one in the world, but very little per capita, and the geographical distribution of coal resources is unbalanced. High-quality coking coal resources are limited, a number of new coking technology has been developed rapidly in order to save this resource. We chosed the 6 meters coke oven in design by comparing all kinds of furnaces.The blending ratio was determined in accordance with design requirements.The calculation was carried out according the equilibrium of material and the equilibrium of heat.The height of the brick lattice was obtained through calculation. We got the height of the chimney through calculating the pressure of different parts of the coke oven. At the same time, the non-process conditions of the oven which was designed were chosen and settled. And some relevant drawings were gotten by using the Auto-CAD program.
