Patent number: 10835903Abstract: 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.Type: GrantFiled: September 19, 2016Date of Patent: November 17, 2020Assignee: UCC Dry Sorbent Injection, LLCInventors: Dennis Engelmann, Stephen Bosshart, Eric Fleckten, Harun Bilirgen, Robert LeDain

Patent number: 8181584Abstract: 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.Type: GrantFiled: June 23, 2009Date of Patent: May 22, 2012Inventors: Harun Bilirgen, Edward Kenneth Levy

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.Type: GrantFiled: March 20, 2006Date of Patent: June 23, 2009Inventors: Edward Kenneth Levy, Harun Bilirgen, Aly Elshabasy

Patent number: 7013815Abstract: 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 wake inducing airfoils (60) each positioned upstream of a plurality of flow channels in the riffler (50) for directing coal flow to the outlet pipes. Each wake-inducing airfoil has a cross-section defined by a width W that varies along its length H for creating upstream turbulence, and a particle wake that preferentially diverts the coal flow to one of the outlet pipes at the splitter junction without affecting primary air flow. For example, each wake inducing airfoil may comprise a rounded convex edge leading to straight tapered sides. The surfaces of the sides may be roughened or textured (63) for promoting turbulent boundary layers. In addition, conventional fixed or variable orifices may be used in combination with the wake inducing airfoils for balancing primary air flow rates.Type: GrantFiled: September 8, 2004Date of Patent: March 21, 2006Inventors: Edward Kenneth Levy, Harun Bilirgen, Ferruhyie Yilmaz, legal representative, Aly Yilmaz, deceased

Patent number: 6966508Abstract: 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.Type: GrantFiled: December 23, 2003Date of Patent: November 22, 2005Inventors: Edward Kenneth Levy, Harun Bilirgen, Elshabasi Ali

Patent number: 6789488Abstract: 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.Type: GrantFiled: October 24, 2002Date of Patent: September 14, 2004Inventors: Edward Kenneth Levy, Ali Yilmaz, Harun Bilirgen
