Abstract
A flare tip for discharging and burning high pressure and low pressure flare gas is provided. A cover is positioned over the upper end of a first pipe through which a high pressure waste gas stream flows. The configuration of the cover allows the high pressure waste gas to burn smokelessly. The upper end of a second pipe that is concentrically positioned around the first pipe is positioned at a lower elevation than the upper end of the first pipe, and the outer edge of the second pipe is tangential to the flat bottom portion of the cover. When the waste gas exiting the upper end of the first pipe does not have sufficient force to raise the cover off the upper end of the first pipe, the flat bottom portion of the cover forms a cap over the upper end of the first pipe while the upper end of the second pipe remains open.
