<p>PROBLEM TO BE SOLVED: To provide a burner for an oxygen-enriched liquid fuel which can improve the combustion efficiency and reduce the total amount of produced NOx as compared with air combustion at the necessary minimum oxygen cost without requiring the drastic change of the present combustion form nor combustion furnace. SOLUTION: In this burner for the oxygen-enriched liquid fuel provided with an oxygen burner section 11 having an oxygen nozzle 15 for combustion around a liquid fuel nozzle 12 and air nozzles 21 around the burner section 11, a swirler 16 which supplies an oxygen gas containing oxygen of >=80% to the burner section 11 and, at the same time, injects oxygen injected from the oxygen nozzle 15 by swirling the oxygen in a spiral form is provided.</p> |
