smolders
Smoldering refers to the process of combustion that occurs without a visible flame. It is a slow, low-temperature burning process where materials are chemically decomposed by heat, releasing smoke but no flame. This type of combustion typically requires a porous material that can trap heat and air, such as wood, peat, or charcoal.
The chemical reaction involved in smoldering is similar to that of flaming combustion, primarily an oxidation
Smoldering fires can be difficult to detect and extinguish because they produce little heat and no visible
