| Abstract: | The present investigation was aimed at demonstrating the pertinent use of a flame/detonation arrester for the safety in the process industry. The experimental data provide information on the performance of a static flame arrester. The experiments were conducted in a 3-m long and 28-mm i.d. tube. The arrester, itself consists in 2-mm i.d. tubes arranged in a honeycomb type structure which is located in the middle of the test tube. This is aimed at promoting heat losses during the passage of the flame. The experiments were conducted with fuel-rich mixtures of methane–ethane–ethylene at initial pressures in the range of 0.1–0.6 MPa. These very rich mixtures were more or less diluted in inert, namely, N2, as well as a mixture of CO2 and Ar, in order to match with compositions that are currently used in the process industry. The experimental results show that this device is appropriate for flame quenching but, in most cases, detonations were not successfully arrested. These unsuccessful operations of the device occurred for flames at a high velocity, namely for Re numbers of the order of or greater than 15,000. |
