Abstract: A carbon reduction assembly adapted for use with wet and dry coal combustion products (“CCPs”). The assembly includes a direct-fired carbon reduction section having a dry material inlet device that is adapted to receive the dry CCPs and a direct-fired carbon reduction section burner unit that is adapted to reduce carbon content in the dry CCPs. The assembly also includes a direct-fired dryer section that is operatively connected with the direct-fired carbon reduction section and has a wet material inlet device that is adapted to receive the wet CCPs and a direct-fired dryer section drum that is adapted to dry the wet CCPs. The assembly further includes a control unit that is operatively connected with the carbon reduction section and the dryer section. An amount of hot gas generated by the carbon reduction section is conveyed to the dryer section, and the assembly is adapted to produce dry fly ash.

Abstract: An inspection device for inspecting storage silos having mobile body with a tray portion for holding internal components for powering and controlling the inspection device, such as a control circuit and power source. Pairs of spaced apart in-line drive wheels are mounted to the tray portion. An external equipment mounting location (space) is provided between the pairs of drive wheels. A universal wiring harness is located within the tray portion and extends to the external mounting location such that at least two non-identical items of inspection equipment can be interchangeably mounted to the mobile body and connected to the wiring harness. A top portion may be secured over the tray portion to enclose the internal components. Optional fenders may be secured over the wheels and external equipment. Preferably, the external equipment can be swapped without having to remove the top portion from the tray portion.
