PURPOSE: A low NOx burner is provided to reduce fuel nitrogen oxide by reducing active oxygen as much as unnecessary air for atomization. CONSTITUTION: A low NOx burner comprises a burner body(11), a fuel nozzle(21), a fuel feeding pipe(31), and an air nozzle hole. The burner body forms a feeding passage(13) for guiding air to a combustion chamber(5). The fuel nozzle forms an oil flowing passage, a gas flowing passage, and a fuel discharging hole. The fuel nozzle is mounted on the fuel feeding pipe. The fuel feeding pipe feeds oil and gas to the oil flowing passage and the gas flowing passage. The air spraying nozzle is arranged along the circumference of the fuel nozzle and sprays the air flowing in the feeding passage to the combustion chamber.
