摘要： A method of disposing of a mixture of oxidizable catalyst material and inert support media. The method comprises introducing inert gas into an enclosure; introducing the mixture into the enclosure; separating the oxidizable catalyst material and the inert support media within the enclosure; maintaining an inert gas environment around the oxidizable catalyst material during separating; exporting the separated inert support media from the enclosure; and grinding the separated oxidizable catalyst material into a powder for disposal as hazardous waste via incineration.

摘要： Embodiments are directed toward a burn bucket. The burn bucket preferably includes a body, a door moveably coupled to the body, and a lifting machine interface coupled to the body. The body preferably defines an inner burn space. The lifting machine interface is preferably configured to receive a portion of a machine that tilts the burn bucket to transition the burn bucket between a closed configuration in which the door is closed and a dumping configuration in which the door is open to facilitate dumping burnt material out of the inner burn space.

摘要： A nozzle (1) is configured to deliver gas into an incinerator such as a waste incinerator (3). The nozzle includes a nozzle pipe (20) and a swirl generator (21). The swirl generator includes a plurality of angularly spaced vanes (24) that are attached to an inner surface (19) of the pipe. The vanes terminate radially inwardly at respective vane inner surfaces (36). A continuous central passage (25) extends axially between the vane inner surfaces. Utilization of the swirl nozzles in connection with an incinerator provide improved gas mixing and avoid having regions with insufficient air to achieve complete combustion.

摘要： A treatment method and apparatus is provided to effectively use a combustible waste such as waste plastic, waste tires, rice husk, wood shavings, PKS, RDF and sludge while maintaining stable operation; to improve the combustion efficiency of a fossil fuel such as coal and coke; and furthermore to reduce the NOx concentration in a cement kiln exhaust gas. An apparatus 1 for treating a combustible, the apparatus comprising: a mixer 3 for mixing a combustible C with a preheated raw material R2, which has a temperature of 600° C. or higher and 900° C. or lower and which is drawn from a preheater cyclone of a cement burning device 10, to gasify the combustible; and a feeder 5 for feeding the gasified combustible and the preheated raw material (mixed raw material M) to a region from an inlet end 13a of the cement burning device to a calciner 12. When the combustible and the preheated raw material are mixed, moisture may be added to cause water gas shift reaction, and the resultant water gas and the preheated raw material may be introduced to the region from the inlet end of the cement burning device to the calciner.

摘要： A system for disposing a high-moisture mixed waste composed of kitchen garbage and water-containing sludge is provided, including a mixed waste storage device, a mixed waste primary-drying device and a mixed waste incinerating device.
The mixed waste primary-drying device includes a mixed waste primary-drying body, a primary-drying material inlet, a primary-dried material outlet, a drying gas inlet and a primary waste gas outlet. A discharging outlet of the mixed waste storage device is connected with the primary-drying material inlet through the first conveying belt. The mixed waste incinerating device includes an incinerator, an incineration material inlet, an incineration material outlet, a combustion-supporting gas inlet and a flue gas outlet. The incineration material inlet is connected with the primary-dried material outlet through the second conveying belt and the combustion-supporting gas inlet is connected with the primary waste gas outlet. The flue gas outlet is connected with the drying gas inlet.-
