Abstract: An apparatus for breaking apart a substance is provided. The apparatus includes a body configured to be selectively secured via a fastener between two surfaces of a container and to break apart the substance upon impact. At least a portion of the body is operative to drop towards a bottom surface of the container upon removal of the fastener so as to facilitate removal of the substance from the container.

Abstract: The system and method for preventing air leakage from the process side to the bearing side of a mill. The system includes a labyrinth seal ring comprising a series of knives defining first and second labyrinth paths from an air inlet to the process side and the bearing side of the system, respectively. The differences in the two paths such as provided by the number of knives used in each path creates a differential pressure drop which biases air from the air inlet to the process side. The labyrinth seal thus provides a reliable and superior method for reducing the potential for particulate in the process side of the mill from damaging the bearing system.

Abstract: The system and method comprising at least one idler wheel for use with a drag chain mechanism. The device for use with the idler wheel has a rotatable shaft for receiving the rotational force of the idler wheel, and transmits that force to a rotation indicator which is external to the enclosed space where the idler wheel is located. The rotation indicator thus provides a reliable method for indicating to an external sensor or operator whether an idler wheel is rotating within acceptable operational parameters.

Abstract: An improved pneumatic particulate conveyance system including a particulate diffuser plate is disclosed. The assembly includes a pipeline with one or more particulate inlets for introducing solid particulates to a prime mover, wherein the pipeline has at least one particulate diffuser plate located within the pipeline. The particulate diffuser plate has a length which runs parallel to the prime mover and occludes at least a portion of a particulate inlet so as to increase the surface area exposed to the conveying air, thus resulting in a more efficient momentum transfer to the particulate. The plate used in the assembly further includes an arcuate trailing edge so as to encourage more particulate falling into the middle (i.e., the higher velocity portion of the profile) of the prime mover.

Abstract: A dry bottom ash handling system contemplates a plurality of hoppers disposed beneath a solid fuel-fired steam boiler. Each hopper includes angled walls converging at a generally rectangular opening controlled by a grate door. Air inlets are provided at intersections between adjacent angled walls to (1) facilitate combustion of unburned fuel in the storage hopper, and (2) facilitate flow of ash through the hopper opening. Ash flowing through the hopper opening enters a crusher and is then conveyed via a vacuum line to a point of disposal including a mobile tank truck that receives heavier ash particles and allows bypassing of lighter particles to a silo.

Abstract: A shaft seal for sealing a rotating shaft relative to a panel or wall of a device from which the shaft extends. The shaft seal has a tubular housing including a packing gland for shaft packings which is floatingly mounted to a wall or panel of the device by an annular diaphragm. A bushing in the bore of the tubular housing causes the tubular housing to move bodily as permitted by the floating mounting when shaft run-out occurs. A connection between the panel and the tubular housing limits rotation thereof resulting from torsional forces derived from shaft rotation. A unitary structure fixed to the shaft for rotation therewith and mounted adjacent an outer end of the tubular housing coacts with an annular thrust washer fixed to said end of the tubular housing to absorb the loads applied to the annular diaphragm and tubular housing acting axially of the shaft.

Abstract: A system for handling fluent solid material includes a material collecting hopper having a bottom provided with several discharge openings, ducts for delivering material from all the discharge openings into a transfer hopper that has one or more bottom outlets. An upright feed conduit with a feed valve is connected to each bottom outlet. If there are two or more bottom outlets at least one may connect to a bypass conduit with a bypass feed valve. A moistening chamber receives liquid at a controlled rate, and material from a feed conduit goes directly into the moistening chamber while material from a bypass conduit does not. Each conduit is provided with a material flow transducer that controls the position of the feed valve in response to the sensed volume of material flowing through the conduit so as to closely control the rate at which material flows from the conduit. Each feed valve or bypass feed valve may be closed so as to load a transport vehicle either with dry material or with moistened material.
