ABSTRACT:
A fuel combuster such as a torch tip, having means therein for cleaning the orifice of the tip, as well as a method of cleaning such an orifice. The combustion device comprises a metallic elongated tube having a forward section terminating in a front end, a middle section and a rearward section, the middle section communicating at its respective ends with the forward section and the rearward section. The rearward section is adapted, suitably at its rearward end, for connection to a source of combustible gas, and is suitably provided with axially positioned fuel jet means for injecting combustible gas into the tube and with apertures for intake of combustion supporting gas to be mixed with the combustible gas. The fuel jet means includes an orifice having an elongated wire passing therethrough. Movement of the wire loosens any dirt in the orifice.
