摘要： PROBLEM TO BE SOLVED: To provide a burner which reduces NOx, and suppresses oscillating combustion during low combustion and low air ratio operation. SOLUTION: A stable ignition area forming means 22 is provided on a downstream side of a main air blast opening 15. In the stable ignition area forming means 22, a flow of combustion air blasted from each main air blast opening 15 is slowed more than a combustion speed, and a stable ignition area to be a stable ignition source for flame is formed. Since the stable ignition area to be a stable ignition source for flame is formed, the whole flame is stabilized, oscillating of an ignition point in the flame is reduced, and oscillating combustion is suppressed. Accordingly, since low combustion and low air ratio operation are carried out, an exhaust gas amount is reduced, heat efficiency is improved, and energy-saving is promoted.

摘要： PROBLEM TO BE SOLVED: To provide a burner and a high-temperature air combustion furnace capable of effectively reducing NOx. SOLUTION: In this burner 1 for the high-temperature combustion furnace, a fuel injection nozzle 12C equipped at the tip of a supply line 12 mixes fuel introduced from an inner tube 12A with steam introduced from an outer tube 12B to be formed into particles and to be injected at high pressure. The fuel steam-atomized is slowly burnt thereby in a combustion chamber, and brought into particles by the high pressure injection to be uniformly sprayed in the combustion chamber. A temperature distribution in the combustion chamber is thereby uniformized, resultingly a high-temperature area is prevented from being formed on an axial line of the burner, and the generation of NOx is also reduced.

摘要： PROBLEM TO BE SOLVED: To provide a burner capable of reducing NOx and suppressing the occurrence of oscillating combustion in low combustion and low air ratio operation. SOLUTION: A reignition means heated by a flame is provided downstream of each main air jet port 15. The reignition means 22 is brought into contact with the flame and heated to an ignition point of fuel or higher. Consequently, when a part of the flame misfires due to blowing away or the like, the reignition means 22 serves as an ignition source, and a mixture (fuel) is instantaneously ignited to stabilize the whole flame. When the whole flame is stabilized, pressure fluctuation in a combustion chamber is reduced to suppress combustion vibration. Low combustion and low air ratio operation can thereby be performed. As a result, the amount of exhaust gas can be reduced, and thermal efficiency is improved to promote energy saving. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a burner and a boiler capable of reducing NOx, CO and dust more effectively. SOLUTION: In the case of a burner 1 of an ω-flow type boiler, air nozzles 13A, 13B are provided with inclination parts 131A, 131B, and combustion air is jetted to be less on the near side to an exhaust port and to be more on the far side therefrom based on the center axis C1. Consequently, a flame is extended out of the center axis C1, to be hardly influenced by a suction force from the exhaust port side, and a part of the flame is prevented from approaching too close to a water pipe or the like near the exhaust port or being in contact therewith, to thereby suppress lowering of a flame temperature and to reduce furthermore generation of CO or dust. Since the flame does not approach the exhaust port side, mixing between high-speed secondary-side combustion air and unburned oil spray particles is accelerated, and simultaneously exhaust gas can be circulated excellently together with the combustion air, and evaporation of the unburned oil spray particles can be accelerated, to thereby realize furthermore reduction of NOx and furthermore reduction of CO and the dust.

摘要： PROBLEM TO BE SOLVED: To provide a burner capable reducing NOx, CO, and soot more effectively.
SOLUTION: Air nozzles 13 (13A and 13B) are provided on an end face 12A of a combustion chamber B side of an outer casing member 12. A shaft line of the air nozzle 13A is slantingly arranged at a predetermined angle θ in relation to an axis of a combustion chamber B toward a tip side. When a total opening area of a main air jet opening 14 of the air nozzles 13 is S2, and a total opening area of small holes 11A of an inner tube member 11 is S1, it is set so that S1/(S1+S2)≤0.3. Combustion air from the air nozzle 13A circulates in a center side of the outer casing member 12, a two staged combustion effect and an exhaust gas recirculation combustion effect are provided, and NOx can be reduced. Since the air nozzle 13A is slanted toward a center side of the outer casing member 12, mixing and vaporization of spray droplets of unburned fuel from a fuel spray nozzle 10A are promoted, and CO and soot can be effectively reduced.

摘要： PROBLEM TO BE SOLVED: To provide a burner capable of positively suppressing generation of NOx, CO, and soot. SOLUTION: An oil feed line 10, and a fuel spray nozzle 10A are arranged in an inner tube member 11. An air nozzle 13 protruding toward a combustion chamber B side is provided on an end face 12A of an outer casing member 12 in a combustion chamber B side. A slant part 131 having a predetermined angle θ with respect to an axis of a combustion chamber B is formed on a tip of the air nozzle 13. Combustion air from the air nozzle 13 is jetted in a direction approaching the axis of the combustion chamber B by the slant part 131, and it is favorably mixed with fuel sprayed from the fuel spray nozzle 10A. Since formation of flame in a fuel spray nozzle 10A outlet vicinity can be prevented by recirculated combustion exhaust gas, vaporization of fuel is promoted, and as a result, generation of NOx, CO, and soot can be positively suppressed.
