The feed injector system includes a first injector port assembly including a plurality of annular channels substantially concentric about a longitudinal axis that define corresponding fluid flow paths that direct a flow of fluid substantially axially therethrough from a respective source to a reaction zone and a second injector port assembly including a flow port surrounded by a plurality of auxiliary ports spaced about a circumference of the flow port, the plurality of auxiliary ports communicatively coupled to a toroidal passage configured to receive a flow of fluid and channel the flow of fluid to the auxiliary ports such that the flow of fluid is discharged from the auxiliary ports having an axial flow component, a radially inward flow component, and a circumferential flow component. | 06-28-2012 |
20120186501 | COAL FLOW BALANCING DEVICES - A flow splitter distributes solid particles flowing in a fluid, such as coal particles flowing in air, through a piping system. The flow splitter includes a divider housing having an inlet configured to connect to an upstream pipe and having an outlet configured to connect to a plurality of downstream pipes, e.g., by way of a divider head. A divider body is mounted within the divider housing. A plurality of divider vanes is included, each extending from the divider body to the divider housing. The divider housing, divider body, and divider vanes are configured and adapted to reduce non-uniformity in particle concentration from the inlet and to supply a substantially equal particle flow from the outlet to each of the downstream pipes. | 07-26-2012 |
20080202393 | Apparatus for Controlling or Regulating the Distribution of Particles in Dust or Granule Form in One or a Plurality of Carrier Gas Streams - The invention relates to an apparatus for controlling the distribution of particles in dust or granule form in one or a plurality of carrier gas streams. The invention further relates to the use of an apparatus in a conveying pipe. An advantageous adaptation of the volumetric flow within the individual flow cross sections is achieved with the invention, so that in particular no channeling can occur, which has favorable effects for a specified material flow rate or material flow rate control particularly in coal-fired power plants. The apparatus according to the invention is furthermore very simple in construction and requires few components. | 08-28-2008 |

20140090583 | COMBINATION OF PRESSURE CHARGING AND METERING FOR CONTINUOUSLY SUPPLYING PULVERIZED FUEL INTO AN ENTRAINED-FLOW GASIFYING REACTOR WITH LONG CONVEYING DISTANCES - A system for fluidizing and conveying a powdery product is provided. The system includes plurality of powder-locking and metering vessels, the vessels each having a conveying line for the powdery product and a control mechanism for the mass flow of the powdery product. The conveying lines are brought together to form a common conveying line and are supplied to a remover of the powdery product. The powder-locking and metering vessels are alternatively fed with the powdery product and tensioned with the fluidizing gas under operating pressure. The control mechanisms of the powder-locking and metering vessels are activated in such a manner that the mass flow sum of powdery product in the conveying lines is identical to the desired value for the mass flow of powdery product to the remover of the powdery product. | 04-03-2014 |

20080302280 | EXHAUSTER FAN BEARING ASSEMBLY AND COOLING SYSTEM FOR PULVERIZER - An exhauster fan bearing assembly for a pulverized solid fuel firing system includes a pedestal housing having an opening at a top portion, the pedestal housing defining an interior space with access thereto through the opening; a bearing housing disposed at the top portion of the pedestal housing, the bearing housing having first and second openings disposed at opposite ends of the bearing housing; first and second bearing assemblies disposed at the first and second openings, respectively; a shaft extending through the bearing housing via the first and second openings, the shaft rotatable about a shaft rotational axis via the first and second bearing assemblies; and a sump housing operably coupled to a bottom of the bearing housing. The sump housing extends through the opening and into the interior space of the pedestal housing. The sump housing defines a reservoir for a lubricant in fluid communication with the first and second bearing assemblies. | 12-11-2008 |
20100000450 | On-line coal flow control mechanism for vertical spindle mills - 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. | 01-07-2010 |
