摘要： This invention is about a coal feeding system (1) which feeds pulverized coal and oxygen separately and vertically through concentric pipes directly to the upper level of the reactor (R) at entrained flow gasification systems. The system (1) consists a top intake (2), a side intake (3), an air supply chamber (4), an oxygen port (5), an ultrasonic sensor port (6), an inner concentric pipe (7), and an outer concentric pipe (8). The system (1) also operates with a coal bunker (K), a screw feeder (B) for adjusting the coal mass flow rate from the coal bunker (K) through the coal feeding system (1) to the reactor (R), and a reactor (R) where the coal are sprayed from the coal feeding system (1) and gasified at high temperatures.

摘要： A system and method for conveying flowable material through a conduit that creates a strong laminar flow of the material surrounded by a boundary layer flow of the same or a different flowable material, such that long transport distances through dramatic elevation and directional changes can be achieved. Some embodiments of the system include a blower assembly, an inlet conduit, an outlet conduit and a mixing chamber, wherein the mixing chamber includes an outer barrel, an inner barrel and an accelerating chamber. Low pressure air is supplied to the system by the blower assembly and mixed with particulate material. The air/material mixture is transported through the mixing chamber into the accelerating chamber and through the outlet conduit. In other embodiments, the particulate material is mixed with the air in the accelerating chamber. Other embodiments of the system include only the mixing chamber, where a flow of at least one flowable material in the form of high or low pressure gas, liquid, and/or particulates suspended within the gas or liquid enters either laterally or axially, forms boundary layer and laminar flows, and exits through the accelerating chamber.

摘要： A screw powder feeder has a rotary screw (12) disposed at the base of a hopper (10). The screw (12) comprises a twist drill bit. Powder is discharged into a chamber (18) and picked-up by a flow of gas. The pressure in chamber (18) is varied relative to the pressure in hopper (10) to control the feed rate for a given screw speed. Ultra-low feed rates are made possible by feeding gas into the hopper (10) through the screw (12) and controlling the relative gas pressures such that the pressure in the chamber (18) exceeds the pressure in hopper (10).

摘要： A high-pressure conveyor discharges a powdery or granular material from a pressurization tank through a discharge unit into a conveyor pipe. The discharge unit includes a guide cylinder or trough mounted on the tank, a screw feeder extending through the guide cylinder and having an end extending into the tank in overhanging relation to an aerator in the tank and the other end coupled to a variable-speed drive unit such as a motor. The material as it is fluidized on the aerator under a high pressure is supplied into the discharge cylinder, from which the material is fed by the screw feeder out of a discharge port in the guide cylinder into the conveyor pipe. A plurality of discharge units may be connected to the tank at angularly spaced intervals for uniform or adjusted distribution of the material to a plurality of locations.

摘要： 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.

摘要： Light dry material, such as asbestos, fed through a tubular screw pneumatic conveyor forms a sealing plug against blow-back in the free space between separated sections of the feed screw. The seal is consolidated by a restrictive orifice plate, which may be flexible, in the sealing plug zone having a passageway smaller than the tubular housing and larger than the shaft. The length of the sealing plug is varied by adjusting a spacing device connected to one of the screw sections to provide the most effective seal for a particular material. Variable spacing is provided, for example, by removable spacer plates or a movable flange which can be locked into one of many axial positions. The air-borne light material is mixed with water to form a slurry for application to a surface.

摘要： AIR LOCK FOR INTRODUCING MATERIAL INTO AN AIR CONVEYING LINE WHILE PREVENTING BLOWBACK TO A MATERIAL SUPPLY CONTAINER. MATERIAL MOVES INTO A RECEIVER AND IS CARRIED TO A MIXING CHAMBER FOR ENTRAINMENT BY AN AIRSTREAM. A SWINGING GATE, SEALED EXCEPT AT THE BOTTOM, CONTROLS FLOW OF MATERIAL INTO THE MIXING CHAMBER, AND THE ENTRAINING AIR ENTERS THE CHAMBER AND FLOWS ACROSS THE BACK OF THE GATE, URGING THE GATE TOWARD CLOSED POSITION. THE GATE IS MECHANICALLY URGED TOWARD CLOSED POSITION ALSO. THE GATE IS PROVIDED WITH SEALS TO COMPLETELY SHUT OFF SUPPLY OF MATERIAL, AND THE GATE AND ITS SEAT COOPERATE TO CUT THROUGH MATERIAL AT THE GATE TO INSURE COMPLETE CLOSURE. BLOWBACK TO THE MATERIAL SUPPLY IS KPREVENTED BY AN AIR OUTLET OUTSIDE THE MIXING CHAMBER ADJACENT THE GATE, AND BY A SURGE CHAMBER ADJACENT THE RECEIVER. CONVEYING AIR CAN BE BYPASSED TO CLEAN THE AIR LOCK.
