Abstract
An igniter is provided for slip-on attachment to the free end of a thermal lance. The igniter includes a slip-on cartridge having a frictional support cap. A priming composition (12) and a primer (13) located within the cartridge. The primer (13) is designed as a friction primer and includes a spiral wire friction element within the primer and connected to the cap. Under the pressure of oxygen introduced into the lance, the cap is forced outwardly with the wire friction element activating the primer to create ignition of the priming composition (12), and the operation of the thermal lance.
