In the previous chapter, the graphic illustration of the experimental apparatus was provided. In this case, the lengths of detonation and protected pipes were 4000 mm and 2000 mm separately. The flame arrester (FA) equipment consisted of flame arrester element (CF-E) and expansion chamber (EC). In the experiment, the CF-E with different porosities and element thicknesses were used. Then, different EC (the conventional, baffle, and extended types) were adopted to connect with the CF-E. There were three types of EC with the same volume and their only difference was in the internal structure, as shown in Fig.  11.2 . In contrast to the conventional EC, the baffle-type EC had an internal annular baffle (inside diameter: 70 mm), which was 30 mm and 240 mm away from the CF-E and the flange end face. Besides, the tube with 155 mm was mounted in the extended EC and the circular hole with 12 mm were evenly distributed along the circumferential direction of tube port (Lin et al. in J Loss Prev Process Ind 87, 2024).

摘要

In the previous chapter, the graphic illustration of the experimental apparatus was provided. In this case, the lengths of detonation and protected pipes were 4000 mm and 2000 mm separately. The flame arrester (FA) equipment consisted of flame arrester element (CF-E) and expansion chamber (EC). In the experiment, the CF-E with different porosities and element thicknesses were used. Then, different EC (the conventional, baffle, and extended types) were adopted to connect with the CF-E. There were three types of EC with the same volume and their only difference was in the internal structure, as shown in Fig.  11.2 . In contrast to the conventional EC, the baffle-type EC had an internal annular baffle (inside diameter: 70 mm), which was 30 mm and 240 mm away from the CF-E and the flange end face. Besides, the tube with 155 mm was mounted in the extended EC and the circular hole with 12 mm were evenly distributed along the circumferential direction of tube port (Lin et al. in J Loss Prev Process Ind 87, 2024).
