Recently, the Ministry of Environmental Protection of China started the development of emission inventories in fifteen Chinese cities. It includes the esmission of PM and PM from stationary sources. However, there is no national standard method in China for stationary source PM and PM sampling. In this study, a two-stage virtual impactor was developed for sampling PM and PM from stationary sources. Its performance was evaluated for four types of sataionary sources, i.e., coal-fired power plant, waste incineration, circulating fluid bed, and converter steelmaking. These four tested emission sources were equipped with high efficiency PM control devices. PM mass concentrations measured in the chimneys of these emission sources were (0.93±0.03), (3.3±0.65), (0.59±0.04), and (0.15±0.04) mg·m, respectively, while the PM mass concentrations were (1.13±0.11), (6.9±0.86), (1.12±0.16), and (0.43±0.15) mg·m, respectively.
最近，中国环境保护部开始在中国15个城市开展排放清单编制工作。其涵盖了固定源的细颗粒物（PM）和可吸入颗粒物（PM）排放。然而，中国尚无针对固定源PM和PM采样的国家标准方法。在本研究中，开发了一种两级虚拟撞击器用于采集固定源的PM和PM。针对四种类型的固定源，即燃煤电厂、垃圾焚烧、循环流化床和转炉炼钢，对其性能进行了评估。这四种受试排放源均配备了高效PM控制装置。这些排放源烟囱中测得的PM质量浓度分别为(0.93±0.03)、(3.3±0.65)、(0.59±0.04)和(0.15±0.04)mg·m，而PM质量浓度分别为(1.13±0.11)、(6.9±0.86)、(1.12±0.16)和(0.43±0.15)mg·m。
