摘要： 为了研究COREX-C3000气化炉,开发了COREX工艺静态模型和实验系统.COREX工艺静态模型是建立在物料平衡和热量平衡基础上的,根据生产现场工艺操作参数设定输入参数,计算结果用于物理实验参数的设定.COREX物理实验系统是建立在相似原理基础上的,模型设有插入式热电偶和观察面板,可获得模型内部信息.实验发现,随着排料速度、石蜡颗粒和玉米颗粒体积比、风温和风量等实验参数增大,风口回旋区越容易发生塌料现象,并初步分析风口回旋区内塌料的影响.

Abstract: COREX static model and experimental system were developed to study the COREX-C3000 melter gasifier. The model was established on the basis of the material balance and heat balance, and its input parameters were set according to the operating parameters of production process. The results of static model were used for setting the parameters of physical experiment. COREX physical experimental system was based on the similar principles. The internal information of the physical model was obtained by thermocouples and observation panel. It was found that with the increase of discharge rates, wax/maize volume ratio, air temperature and air flow, the possibility of collapsing is increased. And the influence of collapsing in the raceway is preliminary analyzed.
