摘　　要：建立了COREX熔化气化炉热态模型;利用石蜡模拟矿石,玉米颗粒模拟焦炭,通过温度传感器对炉内气相温度进行了测定.对测得的模型内温度信息进行处理,可以获得模型内温度梯度.对熔化气化炉在高度方向的温度梯度进行分析,可大致区分炉内填充床、软熔区域、半焦床以及风口回旋区的范围.该研究方法可以比较客观地描述COREX熔化气化炉内部的各区域,以便在进一步研究中分析操作条件变化对炉内各个区域的影响.A physical thermal model of COREX melter gasifier was established.The data of the air temperatures in this model were measured with temperature sensors under different experimental conditions.The temperature gradient could be obtained by processing the data of the air temperatures in this model.The results showed that the packed bed,cohesive zone,drip zone and raceway in the melter gasifier could be roughly distinguished by analyzing temperature gradient along the vertical direction.The zones in the COREX melter gasifier could be described objectively by the method so as to analyze the impact of the operating conditions on the zones in the future studies.
