研究了不同燃烧条件对原木燃烧排放因子和燃烧特性的影响。用两种不同的原木(云杉和山毛榉)和一种型煤(云杉锯末)研究了不同木材类型排放行为的差异。此外，还利用山毛榉木材考察了不同含水率和操作不当对细颗粒物(PM)排放的影响。因此，使用了三种不同含水率水平的原木。误操作由过载和空气不足两种情况模拟。计算了不同燃烧条件下的毒性当量(TEQ)值。结果发现，PM的质量变化最大只有8倍，而TEQ值的变化可能超过80倍(常规山毛榉燃烧，6μg MJ-1；山毛榉在过载燃烧室中燃烧，500μg MJ-1)。特别是，含水率较高(19%)的木材释放出大量的中间产物。
The impact of combustion conditions on emission factors and characteristics of log wood combustion was investigated. Two different kinds of log woods (spruce and beech) and one kind of briquette (spruce sawdust) were used to study differences in emission behavior depending upon the wood type. Beech wood was used to examine additionally the impact of different moisture contents and maloperation on emissions of fine particulate matter (PM). Therefore, wood logs with three different levels of moisture content were used. Maloperation was simulated by an overload scenario and an air deficiency scenario. Toxicity equivalent (TEQ) values were calculated for the different combustion conditions. It was found that PM mass varies only by a factor of 8 at a maximum, whereas TEQ values can vary more than a factor of 80 (regular beech wood combustion, 6 μg MJ–1; beech wood combustion in an overloaded combustion chamber, 500 μg MJ–1). In particular, wood with a higher moisture content (19%) released high amounts of inte...
