PURPOSE: A two-stage fuel and air split-injecting regenerative burner with improved air-fuel mixing efficiency is provided to maintain the existing property of low-nitrogen oxidation and minimize the production of unburned carbon. CONSTITUTION: A two-stage fuel and air split-injecting regenerative burner comprises a first and a second air nozzle(161,163) and a first and a second fuel nozzle(164,165). First air and first fuel are supplied to a first combustion chamber(162). The second fuel nozzle is arranged in the center of the burner, not in the circumference like the second air nozzle, thereby increasing the mixing efficiency between second fuel and air. |
