本研究关注燃煤电厂燃烧过程中挥发性有机化合物（VOC）的分布。采用热解吸技术分析气态排放物（捕获在Carbotrap B吸附剂上）和固体样品（煤、粉煤灰和矿渣）中的VOC浓度。采用经验参数(Y)来评价实际燃烧过程中排放的化合物与煤热解吸分析中获得的化合物之间的关系。Y计算不提供任何关于通过固体排放物如飞灰或炉渣排放VOC的信息。为此创建了一种比较方法。用这种方法得到的结果证实，芳烃和脂肪烃的燃烧几乎完全。氯化化合物主要是在燃烧过程中形成的。
This study concerns the distribution of volatile organic compounds (VOC) emitted during combustion processes in coal-fired power stations. Thermal desorption technique was employed to analyse VOC concentrations in gaseous emissions (trapped onto Carbotrap B sorbent) and solid samples (coal, fly ash and slag). An empirical parameter (Y) was employed to evaluate the relationships between the compounds emitted during a real combustion process and those obtained in coal analysis by thermal desorption. The Y calculation does not provide any information about VOC emissions through solid effluents as fly ash or slag. A comparison method was created for this purpose. The results obtained using this method confirm that combustion is almost complete for aromatic and aliphatic hydrocarbons. Chlorinated compounds are mainly formed during the combustion.
