Provided is a dew condensation prevention device for a discharge chute. A tip end portion of the discharge chute has inverted truncated cone-shaped internal and external chutes, a space is provided between an outer surface of the internal chute and an inner surface of the external chute, and a first air discharge port that communicates with the space is provided between respective lower ends of the two chutes. A cylindrical portion having an air reservoir in the interior thereof is provided to surround an outer peripheral surface of the external chute, and by providing an opening between an inner peripheral edge of a lower surface of the cylindrical portion and the outer peripheral surface of the external chute, a second air discharge port that communicates with the air reservoir is provided. Air input pipes for introduction of dry air are connected to the external chute and the cylindrical portion, respectively.

Biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) is processed to produce useful intermediates and products, such as energy, fuels, foods or materials. For example, systems and methods are described that can be used to treat feedstock materials, such as cellulosic and/or lignocellulosic materials, while cooling equipment and the biomass to prevent overheating and possible distortion and/or degradation. The biomass is conveyed by a conveyor, which conveys the biomass under 10 an electron beam from an electron beam accelerator. The conveyor can be cooled with cooling fluid. The conveyor can also vibrate to facilitate exposure to the electron beam. The conveyor can be configured as a trough that can be optionally cooled.

Illuminating fans for loading docks are disclosed. An example illuminating fan includes a housing defining an airflow chamber and an electrical chamber divided by an internal wall of the housing. The illuminating fan also includes a fan wheel mounted for rotation within the airflow chamber. The fan wheel is driven by a fan motor to generate a current of air passing through the airflow chamber. The illuminating fan further includes a lamp supported by the housing. The lamp is wired to an electrical circuit at least partially contained within the electrical chamber.

The present invention is a new apparatus to efficiently reclaim cement from a horizontal warehouse. This new reclaiming apparatus combines a mechanical cement reclaiming machine, a U Reclaimer Utility Device Apparatus, together with a reduced amount of open air slides, cement is pushed by a rotating chain with rakes on said reclaiming machine, cement is further fluidized through a porous media with low pressure air, cement flow is achieved by sloping said air slides to match the fluidized angle of repose of the powdered material. Further, the present invention introduces a conveying system, composed by a cascade of enclosed air slides and elevator machines, to convey the cement from the reclaiming area to the dispatch hopper. The introduction of these components, together with traditional cement stacking methods and dispatch systems, provides for a highly efficient manner of storing and reclaiming material from a horizontal storage facility.

A method and apparatus for increasing the specific weight of a dry particulate bulk commodity while said commodity is within a transportation vessel, using an array of pokers, these pokers equipped with the means of emitting lateral vibrations into the surrounding commodity and simultaneously creating an air flow through that dry commodity towards the nearest poker of the array.

A simplified submerged chain conveyor system for handling ash produced by large-scale coal fired boilers. The system incorporates an endless chain conveyor system moving a coal/ash aqueous mixture within a conveyor segment having a hydraulically closed duct. The system is adapted for retrofit applications of existing coal-fired boiler installations. In each embodiment the chain conveyor elevates the aqueous ash solution to dewater the ash. In several embodiments the boiler ash hopper is partially flooded with water and the system moves the ash mixture through a water column to the dewatering section. In one embodiment the ash mixture is not submersed but is subjected to water sprays before reaching the dewatering section. Great flexibility is provided in locating and positioning the conveyor system. One unit may be implemented to provide ash handling for multiple boilers. Embodiments are described operable in continuous or batch mode processes.
