Abstract
An electro magnetic controlled platinum infrared filament ignitor has a screw nut, a top pin, an electro magnetic induction coil, a magnetic permeable bolt, a metal wrapped cylinder and a platinum filament. Heat produced by current flowing in the platinum filament actuates the ignitor. The magnetic force set up by the energized coil, and spring force drives the adjustable top pin to the position of the platinum filament. The ignitor is simple in construction with endurable long life and efficient for ignition in most gas turbines, reciprocating engines and gas burners.
