Abstract: The invention provides apparatus and a method for exothermic treatment of feed material to provide an ash. The apparatus includes a housing extending about a central axis and having first and second ends, and a central mixing zone adjacent the first end. A material intake carries the feed material into the housing and gas enters through a first gas inlet at the first end through guides to create an inner vortex extending axially about said axis and the gas then follows an outer vortex which also extends axially but in the opposite direction from that of the inner vortex. However the inner and outer vortices rotate in the same direction. A gas outlet is positioned to receive spent gas from the housing and an ash outlet is positioned remotely from the mixing zone to receive the ash. If preferred, the position of the ash outlet may be incorporated into the gas outlet. A control system is provided to limit the temperature in the feed material in the housing. As a result, in operation, gases can be fed into the first and second gas inlets carrying sufficient oxygen for exothermic combustion of the feed material and having a flow rate to create said inner and outer vortices. The outer vortex meets the inner vortex in the mixing zone to mix both with the inner vortex and with the feed material which will be subjected to exothermic combustion as the feed material is entrained in the inner and outer vortices. The material will pass through the mixing zone repeatedly until the feed material is converted to the desired ash having escape criteria needed to reach and exit through the ash outlet.

Abstract: The invention provides a process for bringing particulate material into contact with a moving fluid in an annular processing zone to create processed material. The zone has a base and the process includes generating a circumferentially directed flow of gas in the zone to develop a circumferentially circulating turbulent bed of particulate material within the processing zone. Particulate material is supplied to the processing zone so that the particulate material is circulated in the processing zone to provide a predictable particle flow path both circumferential of the processing zone and helically of the zone. The flow path has the following characteristics: (i) the flow of fluid is controlled to develop the circulating bed with a width between about 2% to 20% of the bed outer extremity diameter, an inner bed depth of less than 1% of the bed diameter, and an outer bed depth between about 2% to 5% of the bed diameter; and (ii) the flow of fluid is directed at an angle relative to the base of the processing zone in the range of about 10° to 45°; and discharging particulate material from the processing zone after processing in the processing zone.

Abstract: Apparatus is provided for subjecting matter to fluid flow. The apparatus comprises a chamber (10) having an annular fluid inlet (14) beneath a first annular region (22) in the chamber. A second annular region (24) is contiguous with and disposed outwardly of the region (22) between the region (22) and a circumferential wall (12), which has a slope (18) towards the annular inlet (14). Means shown as an annular array of radially extending slots provided in an annular wall portion (FIG. 3) direct fluid through the inlet (14) with vertical and circumferential flow components. In use matter in the chamber is moved in a band continuously along an annular path in the regions. (22, 24). The matter is moved vertically and circumferentially while in the region (22) by the flow therein, is moved out of this flow into region (24) by circumferential force and is directed back into the region (22) by the slope (18) as indicated by arrows (30). Thus the matter is not continuously subjected to the fluid flow while being moved in its annular path in the chamber (10).

Abstract: For processing matter in a turbulent mass of particulate material, a substantially annular processing region (14; 104; 206) is provided and is preferably in the form of a substantially annular processing chamber having a radially inner wall which includes a waist (38; 122). A flow of fluid and matter to be processed are admitted to the processing region through one or more inlets (28, 46; 108, 124; 214, 220) with the flow of fluid being directed generally circumferentially into the processing region. In the processing region, matter to be processed is embedded in a compact turbulent band of particulate material for processing. Once processing is complete, the processed matter is withdrawn from the processing region, preferably by entrainment in an exhaust flow of the fluid.

Abstract: In a process for processing particulate material with a stream of fluid in an annular processing zone, which includes the steps of supplying the particulate material for processing in the zone, discharging processed material from the zone and generating in the zone a circumferentially directed flow of fluid to develop a circulating turbulent band of particles, an improvement to the processing zone which provides a predictable particle flow path both circumferentially and helically of the zone. The improvement comprises directing the flow of fluid to develop a circulating bed with inner bed depth and outer bed depth, a flow of fluid directed at an angle relative to the processing zone base and controlling fluid velocity so that it is greater than the terminal velocity of larger particles point of impact on the bed base and less than the terminal velocity of smaller particles in the superficial space above the bed upper surface.

Abstract: A bed 26 of particulate material is moved in a band continuously along an annular path by passing fluid media having both circumferential and vertical components through the bed along that path. The fluid media comprises combustion gases which are passed through the bed along a portion of the path for heating the particulate material as it passes therethrough and fluid matter to be heated which passes through the bed along another portion of its path such that the fluid matter is heated as it passes through the particulate material which has been heated by the combustion gases.
