Abstract
An igniter for flaring natural gas at the surface of the ground in spaced relation to an oil and/or gas well bore drilling operation wherein excessive gas pressure is encountered during the drilling operation, and comprising a relatively long pipe extending from the well head to a position somewhat remote therefrom for directing excess natural gas away from the well head, a spark plug assembly disposed at the outer end of the pipe and including constantly arcing spark plugs for flaring of the escaping gas and the open end of the pipe, and an annular passageway in the proximity of the spark plugs for providing an adequate supply of oxygen for facilitating the burning of the gas.
