Abstract:
A liquid fuel combustion device utilizes waste and contaminated oils without the need for pre-processing or filtering the fuel stock. And a waste oil fuel burner comprises: a plenum; a pre-combustion chamber located within the plenum; a disc located within the pre-combustion chamber, where the disc has a first surface, an opposing second surface, an edge, and a center; a drive shaft extending into the plenum upon which the pre-combustion chamber and the disc are mounted, allowing the pre-combustion chamber and the disc to rotate within the plenum; a fuel supply tube located such that the fuel supply tube is capable of applying liquid fuel to the first surface of the disc near the center of the disc; and an igniter. The burner may further comprise a combustion blower attached to the plenum via a tangential flow air supply port and an ash collector and dump valve, where the ash collector is attached to the plenum.
Abstract:
An incombustible withdrawing system (302a) withdraws an incombustible from a fluidized-bed furnace (305) having a fluidized bed (312) formed therein by a fluidized medium (310). The incombustible withdrawing system (302a) has a mixture delivery path (316) to deliver a mixture (310b) of the fluidized medium and the incombustible from a bottom (311) of the fluidized-bed furnace (305). The incombustible withdrawing system (302a) also has a fluidized-bed separating chamber (390) disposed downstream of the mixture delivery path (316) to fluidize the mixture (310b) by a fluidizing gas (331) and to separate the mixture into a first separated mixture (310g) and a second separated mixture (310f). The incombustible withdrawing system (302a) includes a return passage (391, 394) to return the first separated mixture (310g) to the fluidized-bed furnace (305), and an incombustible discharge passage (392) to discharge the second separated mixture (310f) to an exterior of the fluidized-bed furnace (305).
Abstract:
Die Verbrennung flüssiger und/oder fester Brennstoffe, insbesondere in Zementdrehrohröfen, erfolgt derzeit üblicherweise mit Sauerstofflanzen oder aussenmischenden Brennern, bei denen dem Brennstoff vor dem eigentlichen Düsenausgang Sauerstoff zur Verbrennung zugegeben wird. Nachteilig bei diesen Brennern ist ihr hoher Sauerstoffbedarf. Erfindungsgemäss wird ein innenmischender Brenner mit Sauerstoff betrieben, bei dem der Brennstoff in einer Mischkammer mit Sauerstoff zerstäubt und durchmischt wird. Dabei verhindert eine hohe Ausstossgeschwindigkeit des hochentzündlichen Brennstoff-Sauerstoff-Gemisches die Beschädigung des Brenners. Die Verbrennung erfolgt wesentlich effizienter als beim Stande der Technik. Insbesondere kann der Brenner eines Zementdrehrohrofens mit einem erheblich erhöhten Altölanteil betrieben werden.

The gasifier system includes a first substantially cylindrically shaped conduit that includes a radially inner surface, a second conduit at least partially within and substantially concentrically aligned with the first conduit, and at least one support member extending between a radially outer surface of the second conduit and the radially inner surface of the first conduit wherein the support member is positioned along a length of the second conduit to facilitate reducing a vibratory response of at least one of the first and second conduits to a flow of fluid through at least one of the first and second conduits.
Abstract:
The present invention generally relates to apparatus and methods for treating waste with high temperature, and more specifically, to apparatus and methods for treating waste with high temperature, which make it possible to construct a small-sized treatment facility so that it is advantageous commercialization, to significantly lower the power consumption of the treatment facility, and furthermore, to treat difficult waste more effectively, thereby making it harmless.
Abstract:
A method of disposing of wastes containing organic compounds which does not generate DXN detrimental to the human body, which comprises (a) the step of charging wastes containing organic compounds into a container cut off from the atmosphere; and (b) the step of supplying oxygen at a quantity ratio of not greater than 1 between oxygen and combustible elements combining with oxygen in the waste inside the container to burn the wastes inside the container, and heating the waste to not lower than 500 DEG C and thermally decomposing them. A fuel can be supplied with oxygen. Further, burning of the fuel with oxygen is preferably carried out by an oxyfuel burner. The wastes containing organic compounds are at least one member selected from the group consisting of shredder dust of automobiles or electric home appliances, city garbage, used tires, various other plastic wastes, waste oils (machine oils), and agricultural chemicals.
Abstract:
Gasified material is converted into process gas and process ash in a shaft-shaped reactor (1). The process gas is drawn off in the region of the hottest reaction zones and cracked in a specially labyrithine flame channel (62) in a controlled manner with the stepwise admission of air and completely converted into an exhaust gas containing few harmful substances, which is taken to a waste heat boiler (33). A dry adsorption agent is added to the exhaust gas in or after this stage. Finally, the exhaust gas thus treated is scrubbed of dust behind the waste heat boiler (33) at temperatures of about 200°C.

An emissions attenuation device can be fluidly connected to the plasma-assisted vitrifier (8) and configured to treat gaseous emissions generated by the plasma-assisted vitrifier (8).
Abstract:
A recycling system processes used oil filters on a continuous basis by shredding (8) the oil filters and then incinerating the shreds in a rotary kiln (20). The shreds are fed into the upper end of an inclined rotating drum kiln (20). The shreds of combustible material and any oil are burnt to produce exhaust gases and ash particles. The remaining metal shreds are discharged at the lower end of the rotating drum (20) through a first port (22). The exhaust gases and ash particles flow from the kiln (20) through a first cyclone (38) which separates out any heavy unburnable pieces. The remaining exhaust gases and ash particles then pass through an afterburner (12) to further ensure complete combustion and minimize air pollution. A second cyclone (14) separates the ash particles from the exhaust gases. An exhauster (13) can be used to induce the flow of exhaust gases and ash particles from the kiln (20) through the afterburner (12) and cyclones (38, 14). This system automatically separates metal shreds and incinerates the combustible materials and oil in the oil filters. Ash particles are also automatically separated by the second cyclone (14) and discharged through a separate port (15).
Abstract:
An X-ray examination apparatus (1) comprises a filter (4) which is arranged between the X-ray source (2) and the X-ray detector (3). The X-ray filter comprises a large number of filter elements (5); the X-ray absorptivity of said filter elements can be adjusted by controlling the quantity of X-ray absorbing liquid (6) in the filter elements. The filter elements are formed by metal capillary tubes, or the wall of the capillary tubes is provided with a metal layer (7). On the metal layer there is provided a dielectric layer (8) and the dielectric layer is covered by a coating layer (9). The dielectric layer is, for example a glass, parylene or polystyrene layer. The coating layer is, for example a Teflon, silane of siloxane layer. The dielectric layer can be dispensed with when a Teflon coating layer is used.
