Abstract
A gas pipe ignitor 10 is provided which is operable to ignite a non-premixed air and fuel mixture and includes an air supply conduit 20 which has an axis ASL, a supply end 22, and a flame end 24 axially spaced from the supply end 22. The gas pipe ignitor also includes a fuel supply conduit 26 extending axially interiorly within at least a portion of the air supply conduit 20 and having an entrance end 28 and an exit end 30. The gas pipe ignitor further includes two branch passages 32 each communicated with the fuel supply conduit 26. The gas pipe ignitor also includes a deflector body 38 disposed in the air supply conduit 20 and is configured relative to the air supply conduit 20 such that air flowing in the air supply conduit 20 flows along a pass through passage PTP from upstream of the upstream most surface 40 of the deflector body 38 to downstream of the deflector body 38. The entrance end 28 of the fuel supply conduit 26 is disposed axially upstream of the upstream most surface 40 of the deflector body 38. The exit end 30 of the fuel supply conduit 26 is disposed relative to the deflector body 38 and the air supply conduit 20 at a location FSE downstream of the upstream most s…
