FIELD: combustion control processes; lighting-up stabilizing the flame of burners of thermal power units.
SUBSTANCE: according to first version, proposed igniter includes plasmatron and auxiliary lighting-up injector mounted in such position that its jet of spraying intersects plasma jet of plasmatron. Lighting-up injector may be made in form of pneumohydraulic injector which is connected with autonomous fuel source or may take fuel from jet of main injector. Igniter may be provided with fuel thermal preparation chamber where plasmatron and lighting-up injector are located in one end other is located in zone of spray of main injector. According to other version, igniter is provided with casing having holes; it is made for of semicylinder.
EFFECT: low cost due to reduced power of plasmatron.
