从两种现代木材燃烧器具中收集了羰基化合物（CCs）的气相排放样品。对用三种原木（桦木、山毛榉和云杉）操作的砖石加热器和用软木颗粒操作的具有正常燃烧和未优化燃烧（其中二次燃烧空气流速降低）的颗粒锅炉进行多次重复。使用2，4-二硝基苯肼（DNPH）柱从稀释排气中进行CC采样。采用气相色谱-选择性离子监测-质谱（GC-SIM-MS）联用技术对CCs-腙衍生物进行分析。在砖石加热器排放物中量化了12种CC，在颗粒锅炉排放物中量化了8种CC。测定了原木、山毛榉和云杉的总羰基排放因子（EF）分别为：桦木113 ± 18 mg kg-1、山毛榉178 ± 31 mg kg-1、云杉171 ± 19 mg kg-1;软木颗粒在正常燃烧条件下的EF为6 ± 0.9 mg kg-1，软木颗粒在非优化燃烧条件下的EF为6 ± 0.9 mg kg-1。
Gas-phase emission samples of carbonyl compounds (CCs) were collected from two modern wood combustion appliances. Multiple repetitions were conducted on masonry heater operated with three logwood species (birch, beech, and spruce) and for a pellet boiler operated by softwood pellet with normal combustion and unoptimized combustion (in which the secondary combustion air flow rate was decreased). The sampling of CCs was performed from diluted exhaust using 2,4-dinitrophenylhydrazine (DNPH) cartridges. The CCs-hydrazone derivatives were analyzed by a gas chromatography–selective ion monitoring–mass spectrometry (GC-SIM-MS) method. Twelve (12) CCs were quantified in the masonry heater emissions and 8 in the pellet boiler emissions. The total carbonyl emission factors (EFs) for logwood were determined to be as follows: birch, 113 ± 18 mg kg–1; beech, 178 ± 31 mg kg–1; spruce, 171 ± 19 mg kg–1; and, for softwood pellet with normal combustion, 6 ± 0.9 mg kg–1 and for softwood pellet with unoptimized combustion, ...
