摘要： An improved apparatus for on-line coal flow control in vertical spindle mills comprising a plurality of independently adjustable flow control elements and positioning rods that adjust the positioning of those flow control elements. Each flow control element is positioned within the discharge turret of the vertical spindle mill along the outer wall of the discharge turret proximate the entrance to its corresponding coal outlet pipe. The adjustable rods are seated on the side of the discharge turret of the coal pulverizer and are connected to the flow control element horizontally. The flow control elements can be independently rotated by +/−90 degrees about the positioning rod axis, and can also be moved back and forth in the horizontal plane. Therefore, each flow control element has two degrees-of-freedom: rotational and linear displacements. The apparatus improves boiler performance by making it possible to operate the boiler with reduced pollutant levels (e.g. NOx, CO) and increased combustion efficiency.

摘要： An improved apparatus for on-line coal flow control in vertical spindle mills comprising a plurality of independently adjustable flow control elements and positioning rods that adjust the positioning of those flow control elements. Each flow control element is positioned within the discharge turret of the vertical spindle mill along the outer wall of the discharge turret proximate the entrance to its corresponding coal outlet pipe. The adjustable rods are seated on the side or top of the discharge turret of the coal pulverizer and are connected to the flow control element horizontally or vertically as the case may be. The flow control elements can be independently rotated by +/−90 degrees about the positioning rod axis, moved back and forth in the horizontal plane, and can also be moved up and down in the vertical plane. Therefore, each flow control element has three degrees-of-freedom: one rotational and two linear displacements. The apparatus improves boiler performance by making it possible to operate the boiler with reduced pollutant levels (e.g. NOx, CO) and increased combustion efficiency. Automated computer control of the control surfaces is contemplated.

摘要： A system for balancing and controlling the distribution of pulverized coal into multiple equal diameter outlet pipes of coal pulverizers for improving boiler performance. The device includes a plurality of flow control elements, one flow control element for each outlet pipe, all positioned a pre-determined distance upstream of the outlet pipes. Each flow control element is mounted on an independent adjustment mechanism and is thereby adjustable in position relative its corresponding outlet pipe to selectively vary the wake of the downstream coal particulate flow relative to primary air flow. The method of the present invention is practiced by monitoring coal particulate flow at the outlet pipes relative to primary air flow or individual flame characteristics, and then compensating for noted imbalances by selectively adjusting the flow control elements, thereby balancing and controlling the distribution of coal and improving combustion efficiency.

摘要： An adjustable device installed at the inlet of conventional junctions/splitters (116) for on-line control of the distribution of coal among the outlet pipes is herein disclosed. The device includes a plurality of flow control elements (60) each positioned upstream of a plurality of flow channels in the riffler (50) for directing coal flow to the outlet pipes. Each flow control element preferably comprises a rounded convex edge leading to straight tapered sides (FIG. 9). The surfaces of the sides may be roughened or textured (63) for promoting turbulent boundary layers (FIG. 9). In addition, conventional fixed or variable orifices may be used in combination with the flow control elements for balancing primary air flow rates. The device allows fine-adjustment control of coal flow rates when used in combination with the slotted riffler, yet it has negligible effect on the distribution of primary air. The combination of the riffler assembly and the coal flow control elements (60) results in closely balanced coal flow. Balanced coal flow is imperative to the optimization of the operation of pulverized coal boiler systems (i.e. reduced pollutant emissions, improved combustion efficiency).
摘要翻译：本文公开了一种可调节装置，其安装在常规接合/分离器（116）的入口处，用于在出口管中煤分配的在线控制。该装置包括多个流量控制元件（60），每个流量控制元件（60）均位于消音器（50）中的多个流动通道的上游，用于将煤流引导至出口管。每个流量控制元件优选地包括通向直锥形侧面的圆形凸缘（图9）。侧面的表面可以被粗糙化或纹理化（63）以促进湍流边界层（图9）。此外，传统的固定或可变孔可以与流量控制元件结合使用，以平衡一次空气流速。该设备允许在与开槽式混合机组合使用时对煤流速进行微调控制，但对一次空气的分配影响微乎其微。烟囱组件和煤流控制元件（60）的组合导致煤流量的平衡。平衡煤流是煤粉锅炉系统运行优化（即降低污染物排放，提高燃烧效率）的必要条件。

摘要： The system and method requiring a diverter plate for an in-line mill. The plate for use with the in-line mill includes an aperture for passage of particulate laden fluid therethrough and a plurality of tabs such that the fluid and the particulate entrained thereon is deflected at a variety of axial angles. The diverter plate thus provides a reliable method such that the milling process and component wear resistance is made more efficient thereby.
