摘要： A combustion apparatus including a mixture feeding pipe for injecting a mixture of pulverized coal for combustion air into a furnace, with the mixture being then ignited. A first gas feeding passage is disposed outwardly of the mixture feeding pipe for feeding oxygen-containing gas into the furnace, with a second gas feeding passage being disposed between the gas feeding passage and the mixture feeding pipe, in a radial direction, for feeding the oxygen-containing gas into the furnace. A projection is disposed between the gas feeding passage and the mixture feeding pipe and extends at an exposed end surface thereof into the furnace beyond an exposed end of the mixture feeding pipe, with the projection being hollow for allowing the oxygen-containing gas to flow within the projection.

摘要： A combustion apparatus including a mixture feeding pipe for injecting a mixture of pulverized coal and combustion air into a furnace, with the mixture then being ignited. A radially outwardly flared flame maintaining ring is provided at a tip end of the mixture feeding pipe, with the maintaining ring being exposed to a reduced atmosphere and to high temperatures due to radiant heat from the furnace. A projection extends into the furnace beyond the flame maintaining ring so as to protect the flame maintaining ring from radiation from inside the furnace thereby suppressing an excessive increase in temperature. Combustion air flows along a surface of the projection so as to provide at oxidized atmosphere. A pulverized coal/air separating member extends within the mixture feeding pipe, and a portion or separation of the flow forcibly occurs is locally formed in a conical end portion of the pulverized coal/air separating member, whereby it is possible to effect a complete combustion in a stabilized manner regardless of the unit capacity and load of the combustion apparatus.

摘要： A burner for pulverized coal has a coal duct for pulverized coal and primary combustion air and a secondary combustion air duct such that the coal and primary air and secondary air mix outside the outlet nozzles of the duct in a mixing zone at which combustion occurs. Coal distribution means in the coal duct create, adjacent the outlet nozzle, at least one outer zone of flow spaced from the coal duct axis and at least one inner zone of flow nearer the coal duct axis. These are means for slowing flow in the outer zone relative to the flow in the inner zone, prior to the mixing zone. To achieve good mixing, and promote NO.sub.x reduction, the coal concentration in the outer zone is higher than in the inner zone. The slowing means may be radially inwardly projecting baffles.

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.

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 combustion burner includes a pulverized coal nozzle, and secondary and tertiary air nozzles provided in concentric relation to the pulverized coal nozzle. A flame stabilizing ring is provided at an outlet end of the pulverized coal nozzle. A separation wall is provided within the pulverized coal nozzle to divide a passage in this nozzle into two passages. A pulverized coal/air mixture flows straight through the two passages, so that recirculation flows of the pulverized coal/air mixture are formed in proximity to the outlet end of the pulverized coal nozzle. As a result, the ignitability of the pulverized coal, as well as a combustion rate, is enhanced, thereby reducing the amount of discharge of NOx.
