In the situation that energy is increasingly grim, how to use high-sulfur fuel effectively and reasonably is a big problem for high-energy consumption cement industry. But high-sulfur fuel will also brought up crusting problem because of higher concentration of circulating and accumulating volatile components. By-pass system can resolve this problem. Rapid-cooling mixer is key equipment for by-pass system. The thermal flow field inside the mixer determines the performance of rapid-cooling mixer directly. CFD method is used to simulate the flow field and temperature field inside mixer. The simulation result help to guide and test the improvement of mixer structure design. After optimization structure design, the mixing of hot gas and cooling air is full and strong inside mixer that leads to excellent cooling effect and good protection for equipment from crusting.
