建立了气化炉下降管传热传质过程的数学模型 ,并进行了数值计算 ,据此分析了下降管内合成气的温度分布与进口流速等参数的关系 .研究表明 ,渭河化肥厂气化炉下降管内的气体温度可以从 16 73K降低到 570K ,且降低气化温度或气化室的出口流速和增加下降管的长度 ,均对激冷室内气体的降温有利
The mathematical model of the heat and mass transfer process of gasifier descending pipe was established and the numerical calculation was carried out.The relationship between the temperature distribution and the flow rate of the syngas in the descending pipe was analyzed.The results showed that the Weihe Fertilizer Plant gasifier Down the pipe gas temperature can be reduced from 16 73K to 570K, and reduce the gasification temperature or the exit of the gasification chamber flow rate and increase the length of the down tube, are beneficial to the chilling room gas cooling is beneficial
