Flare stack height
WebA flare stack or a vent stack used for safe disposal of the vented gases to the atmosphere. The hydracarbons in a flare stack are continuously burned at the tip. While the vent stack simply disposes them into the air at a sufficient height. Flare tip Web7.1.1 Flare Types Flares are generally categorized in two ways: (1) by the height of the flare tip (i.e., ground or elevated), and (2) by the method of enhancing mixing at the flare tip (i.e., steam-assisted, air-assisted, pressure-assisted, or non-assisted). Elevating the flare can prevent potentially
