Popis: |
The premixed flame flashback phenomenon in tubes has been known and studied for several decades. However, the effect of the CO 2 dilution has not been addressed, which is relevant for assessing the safety of oil-producing facilities. For this reason, specific studies of premixed flame flashback in laminar flows are developed here. The objective of this work is to determine the influence of CO 2 dilution on flame flashback in mixtures of hydrocarbons (CH 4 or propane) with air. This is effected by determining the critical Karlovitz number, using both experimental and numerical data. The original results obtained show that CO 2 dilution increases the Karlovitz number when the percentage of dilution on fuel is larger than 25% and 50%, for methane and propane, respectively. This indicates a smaller flashback propensity. |
