Abstract

An apparatus for the automatic combustion of gas produced from oil and natural gas wells at remote locations is described as including an inner conduit having a first and second end that is disposed within a larger dimension outer conduit, each of which share a parallel longitudinal axis. The inner conduit first end is attached to a source of escaping gas and the second end is disposed within the outer conduit. At least one fin is included in the inner conduit for deflecting a portion of the escaping gas through at least one hole that is provided in the inner conduit. The gas thus deflected passes into the area disposed between the outside of the inner conduit and the inside of the outer conduit where it produces a partial vacuum as it continues to travel in the same general direction out of the outer conduit. The partial vacuum draws ambient air into the outer conduit where at least one slow roll fin is present to agitate the ambient air being drawn therein. The agitated ambient air then encounters and mixes with the gas thus deflected and the remainder of the gas proceeding out of the inner conduit and into the outer conduit to produce a volatile mixture that exits from the outer conduit where it is ignited by an electrode which produces an electrical spark (or arc) intermediate the electrode and the outer conduit. The electrical arc is preferably generated by a solar powered source.

Dependent claims

A flare igniter for igniting and combusting a gas prior to the release of said gas into the ambient atmosphere, comprising:

(a) an inner conduit having an inner conduit first end and an inner conduit second end and an inside dimension and an outside dimension and a longitudinal axis;
(b) means for attaching said inner conduit first end to a supply of said gas to be combusted wherein said gas enters said inner conduit at said inner conduit first end;
(c) an outer conduit having an inside dimension larger than said outside dimension of said inner conduit and having an outer conduit first end and an outer conduit second end wherein said outer conduit first end is disposed over said inner conduit and intermediate said inner conduit first end and said inner conduit second end, and said inner conduit second end is disposed within said outer conduit and intermediate said outer conduit first end and said outer conduit second end, and wherein said outer conduit includes an outer conduit longitudinal axis that is parallel with said longitudinal axis of said inner conduit;
(d) at least one deflecting fin disposed in said inner conduit, said at least one deflecting fin extending into said inner conduit for deflecting a portion of said gas entering said inner conduit through at least one hole provided through said inner conduit into an area that is disposed between said outside dimension of said inner conduit and said inside dimension of said outer conduit;
(e) at least one slow roll fin that is disposed within the area between said outside dimension of said inner conduit and said inside dimension of said outer conduit, said at least one slow roll fin having a curvature thereto;
and
(f) means for producing an electrical arc at said outer conduit second end, wherein said means for producing an electrical arc includes means for periodically producing a surge in voltage capable of producing an electrical arc on an electrical output terminal relative to an electrical ground.
