ABSTRACT:
A boiler-heating assembly of a power plant has a fire chamber bounded by four vertical walls each supporting two main burners and two associated ignition burners. Each ignition burner has a cylindrical open-ended chamber with a central pipe terminating in an oil nozzle, a double-walled nozzle tube whose interspace optionally carries a mixture of air with brown-coal dust or oil set in rotation by a tangential feed, and a blower driving air axially through the chamber in an inner and an outer air stream separated by the double-walled nozzle. An annular baffle on the oil nozzle has a solid frustoconical rear surface deflecting the inner air stream radially outward across the air/fuel mixture exiting from the interspace and into contact with the outer air stream, both air streams corotating with that mixture.
