Gas electroburner with electric power supply and assisted ignition

摘要

A gas burner comprises an annular air delivery duct axis, connected to an air supply for delivering a rotating air stream to a combustion chamber. A device injects fuel gas into said combustion chamber along the axis of said annular delivery duct. An arc is formed in the combustion chamber between an upstream electrode along the axis of the annular delivery duct and a counter electrode placed downstream of the upstream electrode. The upstream electrode and counter electrode are connected to an electrical current source. A deflector plate is placed in the path of the air stream at a location close to the upstream electrode. An arc ignition voltage across said upstream electrode and said deflector may be applied.
