摘要： In a burner of construction having a primary nozzle, a secondary nozzle and a tertiary nozzle, a partition wall partitioning the secondary nozzle and the tertiary nozzle and having a flow path change member provided thereon, the partition wall is formed so as to be movable in parallel to the burner axis to control jetting speeds and flow rates of secondary air and tertiary air, whereby it is possible to cool the burner constituent members while reducing NOx. The partition wall is composed of a fixed wall and a movable wall. The burner comprises a bypass passage through which tertiary air in the tertiary nozzle bypasses the tertiary nozzle to flow into the secondary nozzle or the primary nozzle.

摘要： A solid fuel burner and its combustion method suited for encouraging fuel ignition and avoiding slugging caused by combustion ash, wherein a gas of low oxygen concentration (exhaust combustion gas) is used as a carrier gas of such a low grade solid fuel as brown coal. An additional air nozzle for jetting additional air having a velocity component in the circumferential direction of a fuel nozzle is provided in the fuel nozzle, thereby encouraging mixing between the fuel and air in the fuel nozzle. Further, the amount of air supplied from the additional air nozzle is adjusted in response to the difference in combustion loads. Under light load, the amount of air supplied from the additional air nozzle is increased so as to increase the oxygen concentration of the circulating flow formed downstream of the outside of the outlet of the fuel nozzle, whereby stable combustion is ensured. Under heavy load, by contrast, the amount of air supplied from the additional air nozzle is decreased, and a flame is formed away from the fuel nozzle in such a way that burner structures and furnace wall will be less subjected to radiant heat.
摘要翻译：一种固体燃料燃烧器及其燃烧方法，其适用于鼓励燃油点火，避免由燃烧灰引起的堵塞，其中使用低氧浓度（废气燃烧气体）的气体作为褐煤等低等级固体燃料的载气。在燃料喷嘴中设置有用于喷射在燃料喷嘴的圆周方向上具有速度分量的附加空气的附加空气喷嘴，从而促进燃料喷嘴中的燃料和空气之间的混合。此外，响应于燃烧负荷的差异，调节从附加空气喷嘴供给的空气量。在轻负载下，增加从附加空气喷嘴供给的空气量，从而增加在燃料喷嘴出口外侧下游形成的循环流的氧浓度，从而确保燃烧稳定。相比之下，在重负荷下，从附加空气喷嘴供应的空气量减少，并且燃烧器结构和炉壁的辐射热不太可能形成远离燃料喷嘴的火焰。

摘要： A solid fuel burner using a low oxygen concentration gas as a transporting gas of a low grade solid fuel such as brown coal or the like and a combustion method using the solid fuel burner are provided. The solid fuel burner comprises a means for accelerating ignition of the fuel and a means for preventing slugging caused by combustion ash from occurring. Mixing of fuel and air inside a fuel nozzle 11 is accelerated by that an additional air nozzle 12 and a separator 35 for separating a flow passage are arranged in the fuel nozzle 11, and the exit of the additional air nozzle 12 is set at a position so as to overlap with the separator 35 when seeing from a direction perpendicular to a burner axis, and additional air is ejected in a direction nearly perpendicular to a flow direction of a fuel jet flowing through the fuel nozzle 11. An amount of air from the additional air nozzle 12 is varied corresponding to a combustion load. By increasing the amount of air from the additional air nozzle 12 at a low load operation, an oxygen concentration of a circulation flow 19 formed in a downstream portion outside the exit of the fuel nozzle 11 is increased to stably burn the fuel. By decreasing the amount of air from the additional air nozzle 12 at a high load operation, a flame is formed at a position distant from the fuel nozzle 11 to suppress radiant heat received by structures of the solid fuel burner and walls of the furnace.
