摘要： A pulverized coal burner includes a venturi for contracting a flow of a mixture of pulverized coal and primary air toward a central axis of a fuel nozzle 2. A spindle having a cone is provided coaxially with the central axis and gradually expands from an upstream side to a downstream side to cause the mixture to impinge thereon and diffuse. A column extends from the cone and is parallel to the central axis of the fuel nozzle, and a cone extends from the column and gradually narrows from an upstream side to a downstream side. A flow path divider, having a cone gradually narrowing coaxially with the central axis on the downstream side of the spindle, and a cylinder extending from the cone and being coaxial and parallel with the central axis of the fuel nozzle 2, coaxially divides the flow path.

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： The catalytic exhaust gas decomposition apparatus spirals an exhaust gas containing therein a substance to be decomposed and a reactant gas, rectifies the spiral flow, and lets the substance to be decomposed contained in the exhaust gas react with the reactant gas after the spiral flow has been rectified. This arrangement rectifies the spiral flow of the exhaust gas and the reactant gas with a plate-like baffle wall having therein a through hole at a portion near the center thereof. The spiral flow is allowed to pass through the through hole so as to be centralized temporarily. The spiral flow then passes through an enlarged section of a flow path downstream of the through hole before being introduced into the catalyst bed.

摘要： In a catalytic exhaust gas decomposition apparatus according to the preferred embodiment of the present invention, it is possible to suppress variations in velocity distribution of the gases introduced to the catalyst bed. The catalytic exhaust gas decomposition apparatus spirals an exhaust gas containing therein a substance to be decomposed and a reactant gas, rectifies the spiral flow, and lets the substance to be decomposed contained in the exhaust gas react with the reactant gas after the spiral flow has been rectified. This arrangement uses, as a means for rectifying the spiral flow of the exhaust gas and the reactant gas, a plate-like baffle wall having therein a through hole at a portion near the center thereof. The spiral flow is allowed to pass through the through hole so as to be centralized temporarily. The spiral flow then passes through an enlarged section of a flow path downstream of the through hole before being introduced into the catalyst bed. The arrangement helps minimize variations in gas velocity of the exhaust gas flowing into the catalyst bed, thereby allowing a desired decomposition rate to be obtained substantially consistently.
