BURNER MODULE FOR STEEL-CASTING UNITS Russian patent published in 2014 - IPC F23D17/00 F23D14/22 

FIELD: power industry.

SUBSTANCE: invention relates to the field of power engineering. Burner module (10) for steel-casting units includes mixing zone (18), several fuel feed ducts (32) for feeding of combustible fuel to mixing zone (18), and several air feed ducts (34) for combustion air feeding to mixing zone (18), primary burner (42) with annular feed device (30) containing fuel feed ducts (32) and air feed ducts (34), central duct (44) through annular feed device (30); besides, central duct (44) is coaxial to annular feed device (30), and secondary burner (46) located in central duct (44) of burner module (10); burner module (10) includes auxiliary feed ducts (64, 66) for feeding of combustible fuel and/or combustion air to mixing zone (18); with that, auxiliary feed ducts (64, 66) have a cross-section that is smaller than the cross-section of fuel feed ducts (32) or air feed ducts (34), and fuel feed ducts (32) and air feed ducts (34) of the primary burner (42) are provided in an order alternating in a circumferential direction; with that, annular feed device (30) is formed with an annular duct containing several internal ducts; the internal ducts divide the annular duct into fuel feed ducts alternating in a circumferential direction (32) and air feed ducts (34); the annular duct is connected for transportation of one of the types of combustible fuel or combustion air; the internal ducts are used for transportation of another type of combustible fuel or combustion air.

EFFECT: invention allows creating an improved burner module.
