The spontaneous combustibility of biomass char was investigated, focusing on the influence of feedstock type and pyrolysis atmosphere. EFB (empty fruit bunch) char exhibited a higher spontaneous combustibility compared with that of acacia and sorghum chars. This difference is attributed to several factors, including the varying proportions of the three main biomass components, the fundamental structure of lignin between woody and herbaceous biomass, and the presence of potassium in the ash. The study revealed that using steam during pyrolysis reduced the spontaneous combustibility at a fuel ratio of 6 or higher, which is believed to be due to the loss of active functional groups via the steam gasification reaction.
