摘　　要：辐射段是乙烯装置裂解炉的关键组成部分,烃类原料的裂解反应在辐射段炉管内发生,如何实现最佳的裂解反应以及获得适宜的裂解产物分布和较高的产品经济价值是研究人员关注的重点.本文介绍了辐射段炉管内裂解反应和辐射段传热的研究进展,综述了热裂解反应动力学模型和辐射段传热及燃烧模型,阐述了热裂解反应和辐射段传热的影响因素,并介绍了其在蒸汽裂解炉上的应用.Radiant section is the key componet of the cracking furnace, and the cracking reaction of hydrocarbons occurs in the coils of radiant section. In the research of radiant section, the focus is how to obtain the proper product distribution and the high economic benefit. This review reports the research progress of cracking reaction in the radiant coils and the heat transfer in radiant section. The kinetic model of thermal cracking reaction, the heat transfer model and the combustion model are introduced. The factors influcing the thermal cracking reacion and the heat transfer are presented, and the application of the above research on the cracking furnace are introduced as well.
