PROBLEM TO BE SOLVED: To provide a coaxial combustion burner device for multiple liquid fuel capable of simultaneously burning two types of liquid fuel in a burner center shaft within a flame holder.;SOLUTION: The coaxial combustion burner device is provided with a cylindrical sleeve 2 arranged around the burner center shaft C provided in a throat 1 on a wall face of a furnace and having the flame holder 2a at an end and with two oil sprayers 3a, 3b provided in positions symmetrical around the center shaft C within the sleeve 2 and having burner chips 31a, 31b positioned at ends and having blowout directions of liquid fuel different from each other at 90°. Thus, due to the both oil sprayers 3a, 3b, different types of fuel with large volume can be simultaneously burned in parallel, so as to reduce the number of burners and contribute to cost reduction, maintenance, stable operation of the furnace and labor-saving. Even various types of fuel having quality commercially unavailable can be used as main fuel together with other fuel. When fuel nozzles 15a, 15b within air passages 4, 5 are not used for combustion, the nozzles 15a, 15b can be retracted, and thus, burnout of the nozzles 15a, 15b caused by combustion flame of oil fuel in the oil sprayers 3a, 3b is prevented.;COPYRIGHT: (C)2010,JPO&INPIT
