smeulbranden

Smeulbranden, often translated as smoldering fires, refers to a type of combustion that occurs with little to no visible flame. This slow, low-temperature burning process typically happens in materials that are porous and contain a significant amount of combustible matter. Unlike flaming fires, which are characterized by rapid oxidation and the release of heat and light as flames, smoldering involves a slower reaction primarily driven by heat transfer within the material itself.

Common materials susceptible to smoldering include peat, coal, wood, hay, and various types of synthetic materials like foam and textiles. The conditions for smoldering often arise when oxygen supply is limited, preventing a full combustion reaction. This can occur in confined spaces, piles of material, or when a flaming fire has been partially extinguished but the embers remain hot enough to continue the slow burn.

Smoldering fires can be particularly dangerous because they produce significant amounts of toxic gases, such as carbon monoxide, and can persist for extended periods, sometimes days or even weeks. They may appear to be out, only to reignite when exposed to fresh air or increased oxygen. Detecting smoldering fires can be challenging due to the lack of visible flames, and they often go unnoticed until their effects, such as smoke or structural damage, become apparent. Extinguishing smoldering fires can also be difficult, often requiring thorough dousing with water or complete removal of the burning material.
