Abstract
An igniter for a flare stack includes a pair of probes. A hot probe has a tip end free to move in a substantially planar surface. A grounded probe has a tip end extending in at least one direction of the substantially planar surface. The hot probe also has a tip end extending in the substantially planar surface but in a different direction. Movement of the tip end of the hot probe in local wind conditions results in a constant gap being maintained between the tip ends. The pulse generator for the igniter is conventional. A system is shown for stack 90' and shorter and for stacks higher than 90'.
Claims4
An igniter comprising:
- a first probe having a first tip end forming a first linear arcing surface that may move in normal wind conditions in a substantially planar surface;
- a second probe having a second tip end forming a second linear arcing surface at an angle to the first tip end;
- the first tip end being disposed adjacent the second tip end;
- whereby upon movement of the first tip end, a substantially constant gap is formed between the first tip end and the second tip end.
