Abstract: A trunnion seal assembly for joining a stationary inlet/outlet box of a ball tube mill to a rotational interior of the ball tube mill includes an outer ring component configured to be mounted to an outer wall of the stationary inlet/outlet box. An inner ring component is joined to the outer ring component substantially concentrically with the outer ring component. A flexible pad seal is configured to be joined to the outer wall of the stationary inlet/outlet box proximate outer ring component. The pad seal includes a first annular sealing surface. A mill head extension ring configured to be joined to a rotational mill head is located proximate to and substantially concentric with the inner ring component. The mill head extension includes a second annular sealing surface sealingly engaged with the first annular sealing surface of the flexible pad seal.

Abstract: Devices and systems for transporting a material suspended in a fluid, e.g., pulverized coal, that can be assembled about a rotary element are disclosed. The devices and systems comprise a first portion or half of a fan wheel assembly, a second portion or half of a fan wheel assembly, and a plurality of splice plates for connecting the first portion of the fan wheel assembly to the second portion of the fan wheel assembly about the rotary element. Methods of manufacturing and assembling the sectionalized devices and systems are also provided.

Abstract: A deflector device for improving particle distribution within a coal piping system includes a base defining an outer circumference. The base is configured to be mounted inside a pipe such that the base extends partially around the inner circumference of the pipe with the circumferences of the pipe and base being substantially aligned concentrically. A deflector extends radially inward from the base. The deflector is configured to direct a concentrated flow of coal particles toward the center of the pipe.

Abstract: A steam generator includes a furnace configured and adapted to generate a stream of furnace exit gases from the combustion of municipal solid waste fuel. At least one superheater is disposed within an upper portion of the furnace or backpass. The superheater is configured and adapted to superheat fluids within the superheater by facilitating heat transfer between fluids within the superheater and furnace exit gases outside the superheater. At least one waterwall furnace platen is disposed within the furnace upstream from the superheater, the waterwall furnace platen is configured and adapted to lower furnace exit gas temperature at the superheater by facilitating heat transfer between fluids within the waterwall furnace platen and furnace exit gases outside the waterwall furnace platen.

Abstract: The invention includes a grate system for a boiler. The grate system includes a grate unit and a side header guard. The grate unit supports fuel during combustion thereof, and has an upper surface, a lower surface, and upturned lateral edges. The side header guard is arranged along a side wall of the boiler and has upwardly and downwardly projecting fin portions. The upwardly projecting fin portion is adapted and configured to extend over and protect the boiler side wall from abrasion by fuel. The downwardly projecting fin portion is adapted and configured to extend over the upturned lateral edge of the grate unit, inhibiting passage of fuel therebetween.

Abstract: The invention provides a crusher block assembly for a particulate size reduction system including a crusher block having an inboard face configured and adapted to cooperate with a swing hammer in a crusher chamber of a particulate size reduction system to crush particulate, and an outboard face for receiving an adjustment mechanism. The crusher block assembly also includes an adjustment mechanism joined to the outboard face on the crusher block. The adjustment mechanism is configured and adapted to adjust the position of the crusher block along a direction between an inboard location and an outboard location within the crusher chamber. The invention also provides a method of adjusting clearance between a swing hammer and a crusher block in a particulate size reduction system.

Abstract: The invention provides a particulate size reduction system including a grinding chamber, a center shaft defining an axis of rotation and configured for rotational motion within the grinding chamber, a wheel assembly mounted on the center shaft and at least one swing hammer mounted on the wheel assembly. The at least one swing hammer preferably includes a base portion having a first end having a mounting portion for attachment to a wheel assembly of a material treatment system, a second end, an inboard portion proximate the mounting and an outboard portion proximate the second end. The swing hammer also preferably includes a wear pad disposed on the base portion that preferably includes an interrupted surface to improve wear resistance of the swing hammer.
