摘要： Subject 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. Means for Solving the Subject An additional air nozzle 12 for jetting additional air having a velocity component in the circumferential direction of a fuel nozzle 11 is provided in the fuel nozzle 11, thereby encouraging mixing between the fuel and air in the fuel nozzle 11. Further, the amount of air supplied from the additional air nozzle 12 is adjusted in response to the difference in combustion loads. Under light load, the amount of air supplied from the additional air nozzle 12 is increased so as to increase the oxygen concentration of the circulating flow 19 formed downstream of the outside of the outlet of the fuel nozzle 11, whereby stable combustion is ensured. Under heavy load, by contrast, the amount of air supplied from the additional air nozzle 12 is decreased, and a flame is formed away from the fuel nozzle 11 in such a way that burner structures and furnace wall will be less subjected to radiant heat.

摘要： According to a burner of the present invention, a stable combustion is obtained in a wide range from a high-load operation condition to a low-load operation condition even in the case of low quality solid fuel such as brown coal. The amount of air supplied from additional air holes or additional air nozzles 12 can be adjusted depending on the combustion load of furnace 41. At a low load, the amount of air supplied from additional air holes or additional air nozzles 12 is increased, whereby the oxygen concentration in a recirculation zones 19 formed downstream of the outside of a fuel nozzle 11 exit, permits a stable combustion. At a high load, the amount of air supplied from additional air holes or additional air nozzles 12 is reduced, whereby a flame is formed in a position far from the fuel nozzle 11. This suppresses thermal radiation onto a solid fuel burner 42 structure and a furnace 41 wall. The solid fuel burner 42 is applicable to combustion using low-quality solid fuel such as brown coal and exhaust gas as the carrier gas.
摘要翻译：根据本发明的燃烧器，即使在低质量的固体燃料（例如褐煤）的情况下，也能从高负载运行状态到低负载运行状态的宽范围内获得稳定的燃烧。空气量可以根据炉41的燃烧负荷来调节从附加的空气孔供给的附加的空气喷嘴12或附加的空气喷嘴12.在低负载下，从附加的空气孔或附加的空气喷嘴12供应的空气量增加，形成在燃料喷嘴11外侧的下游的再循环区域19可以稳定地燃烧。在高负载下，从附加空气孔或附加空气喷嘴12供应的空气量减少，从而在远离燃料喷嘴11的位置形成火焰。这抑制了对固体燃料燃烧器42结构的热辐射和炉41墙。固体燃料燃烧器42适用于使用诸如褐煤和废气的低质量固体燃料作为载气的燃烧。

摘要： A pulverized coal burner includes a pulverized coal nozzle for jetting a mixture of pulverized coal and primary air, a secondary air nozzle and a tertiary air nozzle, concentrically arranged around the outer periphery of the pulverized coal nozzle, and a tube expanded portion at the end of a partition wall separating two adjacent air nozzles. A flow shift means such as a guide plate for shifting the secondary air in the secondary air nozzle so as to flow along the tube expanded portion is provided. The secondary air is jetted outwardly by the guide plate, and mixing of the secondary air and the tertiary air with pulverized coals is delayed, whereby an amount of NOx is decreased.
