| Resumen |
Cutting an opening in a low-pressure gas pipeline with an oxy-acetylene torch can produce an open flame up to 2.5m long. If the escaping gas is directed into a funnel-shaped collector attached to a vertical stack, it can be flared outside the trench where cutting and welding operations normally take place, thus improving working conditions in the trench. To ensure that the flare itself does not endanger surrounding buildings, trees, equipment, etc., it must be kept at a safe distance from surrounding objects. Experiments with a full-scale model of a 300-dekaPascal pipeline and flare showed that the maximum flame length attained at any wind speed is 4.5m. At 6m from the flare, temperatures of only 50°C were measured at maximum flame length; thus 6m represents a safe distance, even for workers if no toxic combustion products are present. |
