摘要： 建立了二维COREX熔化气化炉物理模型.利用石蜡模拟DRI,玉米粒子模拟焦炭和块煤,通过高速摄像仪对炉内软熔区域变化进行记录,根据实验前后炉内物料颜色的变化,提出一种图像处理方法.利用该方法可以得到炉内软熔区域边界,从而得到其位置及厚度.对本实验条件下软熔区域的变化过程进行了分析,所提方法可在进一步研究中分析操作条件变化对炉内软熔区域的影响.

Abstract: A two-dimensional physical model of COREX melter gasifier was constructed to study experimentally the melting behavior of burden in the furnace. Paraffin was used to simulate DRI, and corn was used to simulate coke and lump coal. High-speed camera was used to record the experimental images. An image processing method was developed to characterize the cohesive zone boundary according to the color change of burden before and after the experiment. The proposed method can give the cohesive zone boundary, and thus the position and thickness can be obtained. The variation of the cohesive zone under various experimental conditions was examined. The effect of operation condition on the cohesive zone can thus be analyzed by the proposed method in the future studies.
