Abstract:
A pyrolyzer has a heated inner housing that includes first and second conveyors. Preferred conveyors have independent or at least potentially independent flows of material to be pyrolyzed. All suitable conveyors are contemplated, including especially screw conveyors, or combination of screw and paddle conveyors. Both first and second conveyors can be disposed within a common lumen, with a partial divider between them. An alternative divider is also contemplated that more or less divides the inner housing into two lumens. Thus, the lumens can be entirely distinct, or can have cross-flow of gasses and/or material being pyrolyzed. Heat transfer fins can be advantageously attached, extend from, or be otherwise coupled to the inner housing to assist in transfer of heat into the lumen(s) of the inner housing.
Abstract:

Abstract:
The invention relates to an installation, especially a low-temperature carbonization and combustion plant, and to a method for thermal removal of waste. The installation comprises a heating chamber (10) for thermal waste (A) processing. A drying drum (10) is arranged upstream from the heating chamber (10) in order to dry the waste. Said drum is preferably rotatable and is heated via inner heating tubes (54). Steam (D) or hot gas (H) is provided as a heating medium. Preferably, steam (D) is provided by a steam generator which is preferably arranged in a flue-gas purification unit between a waste heat boiler (28) and an electrostatic filter (33). The yield of energy stored in the waste (A) is improved by drying or pre-drying the waste (A) before actual pyrolysis occurs in the heating chamber.
Abstract:
The process thermally treats granular solid waste in an incinerator installation (10) comprising: i) a generally vertical, cylindrical riser pipe (52); ii) a vertically extending annular chamber (24) surrounding the riser pipe and containing a fluidized bed of granular inert material; and iii) a burner (22) for producing an upwardly extending flame in the lower portion of the riser pipe. Granular solid waste is supplied at a constant flow rate to the bed, directly or through the burner. Granular solid waste and bed material is transferred from the lower portion of the annular chamber to the lower portion of the riser pipe directly in the flame. The flame burns the granular solid waste, heats the inside of the riser pipe to a temperature >/= 900 DEG C, and produces flue gas that pneumatically transports the granular solid waste and bed material upwardly from the lower portion to the upper end (53) of the riser pipe at a speed of 3-15 m/s to create a high turbulence thereby increasing absorption of heat by the granular solid waste and oxidation of the organic components of the granular solid waste. The granular solid waste and bed material is discharged in the annular chamber through the upper end of the riser pipe, treated granular solid waste is collected from the fluidized bed to maintain the height of granular solid waste and bed material substantially constant, and flue gas is evacuated.

Abstract:
A plant for incerating explosive substances has an incineration reactor (1) and a conveyor device (11) with a plurality of incineration trays (16) which travels, preferably circulates, inside and outside the reactor. The incineration trays (16) are charged outside the incineration reactor (1) with the explosive substances to be burned, conveyed into the reactor to an ignition device (burner (22)) for igniting the explosive substances and conveyed further inside the reactor, together with the explosive substances being burned, and finally emerge from the reactor when combustion is complete. The emission from the incineration of explosive substances can be substantially reduced under conditions of complete personal safety by installing the incineration reactor (1) inside a shatterproof, explosion-proof tunnel (2).
