ABSTRACT:
In a system for moving large quantities of pulverulent material from receiving hoppers, such as those of a fly ash precipitator, into a pressurized air conveyor pipeline, separate auger conveyors move material from a first line of receiving hoppers and from a second line of receiving hoppers downstream into gravity material inlets at opposite ends of an effectively airtight pressure conveyor casing. In the casing auger conveyor flights of opposite hand and substantially smaller than the casing means it toward a central outlet through which it drops into the pressurized air conveyor pipeline. Above the outlet the auger conveyor shaft has radial material agitating rods. The system is cycled to alternately feed material into the pressure conveyor casing at receiving hopper pressure, which is about atmospheric pressure, and out of the pressure conveyor casing at pipeline pressure. The pressure conveyor is pressurized through a series of air pressure pipes spaced along the casing substantially tangent to the lowermost part thereof, and casing pressure is relieved through a pipe above the central outlet.
