FIELD: energy.
SUBSTANCE: invention relates to power engineering and can be used for arc ignition of a steam-oil atomizer of power plants boilers. Method of arc ignition of a steam-oil atomizer consists in steam-oil mixture supply from the nozzle in the boiler furnace and high-pressure voltage supply on the rod electrodes of the arc igniter ignition lance to produce arc discharge on them, by stretching arc length coaxially to the ignition lance, supplied into space between coaxially installed insulator of the rod electrode and cylindrical tubular of the ignition lance by excess air, and ignition of fuel from the atomizer.
EFFECT: invention provides fast and reliable ignition of the steam-oil atomizer, which requires minimum fuel oil consumption, as well as eliminates early wear and burning contacts of the ignition lance.
