摘要
An igniter nozzle is positioned for ignition of coal leaving the coal nozzle. A separator separates coal from air. Coal mixed with air is conveyed from one of the pulverisers to the separator. Coal is conveyed from the separator to the ignitor nozzle. A third air stream is heated from a source other than the combustion products. The third air stream is caused to flow to the furnace at the ignitor nozzle. A lighter is positionable near the outlet of the ignitor nozzle for igniting coal issuing from the nozzle.
