Abstract
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.
