Abstract
A torch assembly for igniting a target fuel includes a torch including an elongate wand having a handle end and an opposing forward end, and a torch head located on the forward end of the wand. The torch head has a central axis. The torch head includes an outer surface, a fuel supply chamber, and a plurality of circumferentially spaced apart jet channels fluidly connecting the fuel supply chamber to the outer surface. Each jet channel is configured such that, when a pressurized flow of a gaseous torch fuel is supplied to the jet channels through the fuel supply chamber and ignited, each jet channel directs a respective flame jet forwardly and radially outwardly from the outer surface at an acute angle to the central axis.
