Industry production practice and CFD (Computational Fluid Dynamics) numerical simulation technology are integrated together in the study of the fan cooling effect on an overseas 10000t/d (ton/day) cement rotary kiln. The spot data of a 10000t/d cement production at home were collected and studied, which provided the vital data for numerical simulation of the fan cooling effect. Then aiming at the working ambient conditions of the overseas 10000t/d cement production line, the fan cooling effect of its rotary kiln was numerically simulated by considering natural convection and radiation heat-loss. Finally, based on the results of the simulation, a conclusion is drawn that the fan cooling effect is good enough to make the overseas rotary kiln safely run at its ambient conditions.
