Title:
COAXIAL COMBUSTION BURNER DEVICE FOR MULTIPLE FUEL AND METHOD OF OPERATING THE SAME
Document Type and Number:
Japanese Patent JP2010071575
Kind Code:
A
Abstract:

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.

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 with a folding-fan shape provided 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 tips 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 a boiler and labor-saving. Since even various types of fuel having quality commercially unavailable can be used as main fuel together with other fuel, industrial availability can be improved.
