Massive use of wood biomass is usually associated with its long-term, large-scale storage in power plants and heating plants. Long-term storage of wood biomass (more than 3 months), in large volumes, brings risks from the point of view of human health or property treatment. This work aimed to verify how the long-term storage of wood chips from beech wood in small piles affects their energy properties and whether in this way it is possible to reduce the risk of fire by self-heating in piles and the volume of phytopathogenic spore production. Four experimental piles, each with a base of 4 × 4 m and a height of 2 m, were established. After 6 months, one of the piles was disassembled and samples from 0.5 m, 1.0 m, and 1.5 m height levels were taken for analysis. The results of the experiment confirmed that the energy properties of wood chips stored in small piles significantly deteriorate after more than half a year of storage. It has also been confirmed that the choice of this method of storing in smaller, spatially divided piles can lead to a significant minimization of the risk of spontaneous combustion and fire. The length of the storage period did not have a positive effect on the abundance of phytopathogen content in the stored piles. With the length of storage, only the number of identified harmful species of phytopathogens were changed and, at the same time, their number of colonies increased.

小规模堆放木屑作为消除某些风险的工具

木材生物质的大量使用通常与其在电厂和供热厂中的长期大规模存储有关。从人类健康或财产处理的角度来看，木材生物量的长期储存（超过3个月）会带来风险。这项工作旨在验证将山毛榉木中的木屑长期储存在小堆中会如何影响其能量特性，以及以此方式是否可以通过堆中自热和减少植物病原性孢子的数量来降低着火的风险生产。建立了四个实验桩，每个桩的基底为4×4 m，高度为2 m。6个月后，拆解其中一堆，并从0.5 m，1.0 m和1.5 m高度的样品中取样进行分析。实验结果证实，在存放超过半年后，以小堆存放的木片的能量特性会显着降低。还已经证实，选择在较小的，空间上分开的堆中存储该方法可以导致自燃和着火的风险显着最小化。贮藏期的长短对贮藏堆中的植物病原菌含量没有积极的影响。随着储存时间的延长，仅已确定的植物病原体有害种类的数量发生了变化，同时，其菌落数量也有所增加。按空间划分的桩堆可以极大地降低自燃和着火的风险。贮藏期的长短对贮藏堆中的植物病原菌含量没有积极的影响。随着储存时间的延长，仅已确定的植物病原体有害种类的数量发生了变化，同时，其菌落数量也有所增加。按空间划分的桩堆可以极大地降低自燃和着火的风险。贮藏期的长短对贮藏堆中的植物病原菌含量没有积极的影响。随着储存时间的延长，仅已确定的植物病原体有害种类的数量发生了变化，同时，其菌落数量也有所增加。
