摘要： A combustion process for burning fuel in a combustion chamber is provided. The process includes supplying fuel and air to a burner, the amount of air supplied being at least as much as required for stoichiometric combustion of the fuel and subsequent dilution of the combustion process. The process also includes injecting the fuel and all the air from the burner directly into the combustion chamber in a substantially unmixed state as a fuel stream within an air stream. Fuel is injected from a nozzle, which is nested within an air nozzle. The fuel nozzle ejects a fuel stream of such thickness that the fuel burns in the combustion chamber as a diffusion flame with a high surface-to-volume ratio at or close to the stoichiometric fuel/air ratio. The flow of air through the air nozzle is subject to the venturi effect.

摘要： A description is given of a burner for introducing solid, liquid or gaseous fuel to a burning zone of a kiln, such as a rotary kiln for manufacturing cement clinker or the like, said burner comprising a number of substantially concentric ducts (1, 2, 3), being parallel to the main axis B3 of the burner, for conveying fuel and primary air to nozzle openings, as well as a number of additional ducts (4, 6, 7, 8) for conveying solid, fluid or gaseous fuel to separate nozzle openings, said additional ducts being located in the central part (10) of the burner. The burner is characterized in that it comprises means (4a, 5) for changing the flow direction of the fuel which is introduced via at least one of the additional ducts in the central part (10) of the burner, relative to the main axis B3 of the burner, at least in an ascending direction. This will allow the individual fuel particles to travel in a curved, approximately ballistic path, thereby extending the time they can be maintained in the flame. Another advantage of this configuration of the burner is that the large particles will attain the highest, and hence the longest, path, since the path of the smaller particles will to a greater extent than is the case for the large ones be deflected by the primary air which is injected via the outer annular primary air nozzle which is parallel to the main axis of the burner. Hence it will be possible to achieve a more uniform combustion of all particles, regardless of their size. It will be possible to change the path of the particles by altering the velocity or direction of injection.
摘要翻译：说明了将固体，液体或气态燃料引入窑的燃烧区域的燃烧器，例如用于制造水泥熟料等的回转窑，所述燃烧器包括多个基本上同心的管道（1,2， 3），平行于燃烧器的主轴线B3，用于将燃料和一次空气输送到喷嘴开口，以及用于将固体，流体或气体燃料输送到多个附加管道（4,6,7,8）单独的喷嘴开口，所述另外的管道位于燃烧器的中心部分（10）中。燃烧器的特征在于，其包括用于改变燃料的流动方向的装置（4a，5），其通过燃烧器的中心部分（10）中的至少一个附加管道相对于主轴线B3引入至少沿上升方向。这将允许单个燃料颗粒在弯曲的大致弹道中行进，从而延长它们可以保持在火焰中的时间。燃烧器的这种配置的另一个优点是，大的颗粒将达到最高的，并且因此是最长的路径，因为较小的颗粒的路径会比大的颗粒的路径偏移大的程度通过外部环形一次空气喷嘴喷射空气，其平行于燃烧器的主轴线。因此，无论其尺寸如何，都可以实现所有颗粒的更均匀的燃烧。通过改变注射速度或方向可以改变粒子的路径。

摘要： The invention relates to a flame burner having a nozzle (10) disposed in a head, wherein in addition to annularly disposed gas supply channels (11) the nozzle has a central gas supply opening (12), which has a laval nozzle-like region and a stabilizing region having a consistent diameter connected thereto in the flow direction. In order to flame burn a metallic surface the oxygen gas guided through a central nozzle of a flame burner is incited to oscillate in such a manner, such that a pulsating oxygen flow exiting the nozzle mouth is formed at the speed of sound, or at supersonic speed.

摘要： A baffle for a regenerative burner has a primary reactant port, secondary reactant ports, and internal flow paths. The primary port is centered on an axis. The secondary ports are arranged in an array that is asymmetrical relative to a plane containing the axis. The internal air flow paths convey secondary air streams from the regenerative bed to the secondary ports. A reactant delivery structure for use with the baffle includes a pilot burner, a main fuel conduit, and a primary air conduit. The pilot burner projects a pilot flame toward the primary port. The main fuel conduit has an annular outlet that directs a main fuel stream over the pilot flame and outward from the primary port. The primary air conduit has an annular outlet that directs a primary air stream outward from the primary port over the main fuel stream.

摘要： A process for producing metallic ultra-fine powder, which can use a raw material which is spread over a wide range, and control freely the grain size of the metallic powder to be produced, at low cost and high safety. The process for producing the metallic ultra fine powder consists of using a burner and a furnace which can generate a high temperature reductive atmosphere, and an apparatus for separating gas which is generated in the furnace from powder to recover the powder. The burner has a function of blowing a powdery metallic compound as a raw material into a high temperature reductive flame. The raw material powder is efficiently heated in airflow of a high temperature reductive flame, thereby being reduced rapidly into metallic ultra-fine powder. At this time, the grain size of the metallic ultra-fine powder is controlled by adjusting the oxygen ratio (i.e. the ratio of amount of the burning-assist gas supplied to the burner to the amount of the burning-assist gas required for completely burning the fuel).
