摘要： 利用COREX熔化气化炉半周冷态模型，通过跟踪示踪颗粒的运动信息，得到观察面板处风口回旋区域的颗粒速度场. 通过与目测结果的对比，确定超过0.15 m/s的颗粒速度标量场为风口回旋区域. 实验得到的回旋区边界可为回旋区理论或数学模拟提供准确的边界条件.

Abstract: A new method has been developed to determine the raceway boundary in cold model of COREX melter gasifier, so as in blast furnace, granular drying, etc. The particle velocity contour criterion of raceway boundary definition is 0.15 m/s, and the precise raceway boundary can be obtained through this method. It is very important for the theoretical and mathematical modeling of gas and solid flow and chemical reaction in and around the raceway region.

Key words: COREX, melter gasifier, raceway, physical simulation, particle velocity contour
