摘要: 在氢气和氯气燃烧合成氯化氢的工业过程中,充分利用燃烧热是氯化氢合成炉设计和操作的长期目标。本文通过建立炉内反应及传热模型,采用微元段积分方法对副产蒸汽氯化氢合成炉进行模拟计算,计算结果与实际工况相符。计算结果表明:在整个传热过程中,辐射传热占主导地位,辐射传热量约是对流传热量的9倍;副产蒸汽移走了大部分反应热,能量利用率达到69.58%;蒸汽发生系统的有效能损失较大,副产蒸汽有效能为总有效能的37.71%。

Abstract: Hydrogen chlorine (HCl) is synthesized by hydrogen and chlorine in the industry. Making full use of the reaction heat is our long-term goal in the design and operation process of HCl synthesis furnace. The model of reaction and heat transmission in the furnace is established on the byproduct steam HCl synthesis furnace. The simulation calculation is conducted by the method of infinitesimal section integral and the results are according with actual wo- rking conditions. The results show that: the radiation heat transfer is predominant in the whole heat transfer process and its heat transfer quantity is 9 times higher than convective heat transfer; Most of reaction heat is taken away by by- product steam and the ratio of energy utilization is up to 69.58%; The major loss of effective energy is in the generation system of stream and the effective energy of byproduct steam is only 37.71% of the whole effective energy.
