Abstract
1,020,486. Purifying exhaust gases; igniters. ASSOCIATED ENGINEERING Ltd. Nov. 22, 1963 [Aug. 22, 1962], No. 32254/62. Heading F1B. The ignition means in an engine cylinder or in an afterburner device for purifying the exhaust gases comprises an induction coupled plasma torch energized from a radio frequency generator. As applied to an afterburner, Fig. 4, the exhaust gases, with secondary air from inlet 6, are fed towards the plasma torch igniter 2 along one side of a heat transfer device 7 through which they are heated by the hot gases flowing away from the zone of the igniter. The plasma torch 2 comprises a refractory tube 3 e.g. of quartz or ceramic, which is open at its inner end and supplied with gas through a preferably tangential inlet 5, the tube being surrounded by a radio frequency coil 4 which, when energized by an oscillator, e.g. at a frequency of several megacycles, heats the ionised gas in the tube 3 to a very high temperature, producing a flame which issues from the open end of the tube. The operation of the torch may be initiated by a heated filament or glow plug, a graphite rod or refractory wire heated indirectly by the coil 4, or a radio isotope such as strontium 90. A plasma torch may be arranged in each combustion chamber and energized according to the firing cycle by pulses of radio frequency energy.
