摘要：
The leaching properties of trace elements in wood ash were examined to evaluate the safety of using woody biomass ash. Boron and selenium were detected in high concentrations not only in ash collected from an electric furnace but also in combustion ash from a small wood stove. As for the leaching of trace elements, the influence of calcium compounds on boron and selenium in wood ash is proposed. The leaching of trace elements is enhanced when calcium carbonate is the calcium compound in ash, although it is inhibited in the case of portlandite. There is little information in the literature that can be used to determine the effective use of wood biomass ash, thus limiting the development of woody biomass for applications such as thermal power generation.
