摘　　要：阴燃是一种低温、缓慢、无焰的燃烧现象.阴燃既能引起地球上规模最大、持续时间最长的森林火灾,也有望成为一种清洁、安全且低成本的固废处理新技术.然而,当前学界对维持阴燃的临界供氧极限仍缺乏深入理解.该文章综述了文献中探索阴燃临界供氧极限的实验和数值模拟方法,并从临界供氧浓度和临界供氧速率的角度,探讨了不同燃料和供氧模式下的临界供氧特性及其影响因素,以期为未来系统性研究及认识近极限条件下阴燃的临界供氧特性提供参考.Smoldering is a slow,low-temperature,and flameless combustion phenomenon.Smoldering combustion can not only cause one of the largest and most persistent wildfires on Earth but also potentially serve as a clean,safe,and low-cost technology for solid waste treatment.However,our current understanding of its critical oxygen supply limits remains insufficient.This paper reviews the experimental and numerical simulation methods related to the critical oxygen supply limits of smoldering.It further discusses the characteristics and influencing factors of critical oxygen supply under different fuels and oxygen supply modes,from the perspectives of critical oxygen concentration and critical oxygen supply rate.This review aims to provide a reference for future systematic research and understanding of the critical oxygen supply characteristics of smoldering combustion under near-limit conditions.
