可吸入细颗粒物（dp）的形成是固体燃料燃烧过程的不期望的副作用。这些颗粒会在人体呼吸系统中积聚，从而导致严重的肺损伤。因此，了解这些颗粒的形成对于避免或减少释放到大气中的细颗粒物的量至关重要。为了研究颗粒物的形成，开发了旋流甲烷辅助煤粉燃烧试验台，该试验台允许在燃烧过程中进行侵入式和非侵入式测量。在这项工作的范围内，所开发的试验台进行了说明，并提出了激光多普勒测速仪（LDV）测量的结果。在火焰的不同高度水平进行速度测量，以研究火焰结构。在这项研究中，它表明，实验装置实现了稳定和可重复的燃烧条件，以便在进一步的工作进行详细的调查。
The formation of inhalabe fine particles (dp) is an undesirable side effect of solid fuel combustion processes. These particles can accumulate in the human respiratory system and thus cause severe lung damage. Therefore, an understanding of the formation of these particles is of crucial importance to avoid or reduce the amount of fine particulate matter released into the atmosphere. For the investigation of particulate matter formation, a swirled methane assisted pulverized coal combustion test rig was developed, which allows intrusive and non-intrusive measurements to be performed during the combustion process. Within the scope of this work, the developed test rig is described and results of laser Doppler velocimetry (LDV) measurement are presented. The velocity measurements were performed at different height levels of the flame to investigate the flame structure. Within this study, it is shown that the experimental setup achieves stable and reproducible combustion conditions to allow detailed investigations in further works.
