During conventional boiler ignition

the fuel oil will be primarily used to preheat the furnace to reach the operating temperature

then the pulverized coal is delivered to the furnace to be ignited.This consumes a large amount of oil

especially for igniting low-volatile coals.To save the consumption of fuel oil

this paper theoretically focused on the experiment of igniting low-volatile coal in a tiny-oil-burner under oxygen-enriched conditions

and the oxygen-enriched tiny-oil ignition technology was applied in a 300 MW unit boiler successfully.The experimental results indicated that

the ignition of low-volatile coal was achieved in a tiny-oil-burner under oxygen-enriched conditions

and appropriate amounts of pure oxygen feeding into the burner could promote the burn out of fuel oil and pulverized coal

which was beneficial to reducing black smoke from oil and saving fuel oil during ignition process.
