Disclosed are adjustable kiln flights for rotary kilns and associated methods. The kiln flight includes a base configured to be secured to a rotary kiln surface of a rotary kiln. In some aspects, the kiln flight includes a flight body rotatably supported on the base such that an angular orientation of the flight body is adjustable. In various examples, the kiln flight includes a height adjuster movably supported relative to the base such that a height of the kiln flight is adjustable. A method of controlling a rotary kiln with the adjustable kiln flight includes supporting a kiln flight on a base that is secured to an inner kiln surface of a rotary kiln, and adjusting at least one of the angular orientation of the kiln flight or the height of the kiln flight.

The invention relates to a burner pipe for a rotary kiln for producing activated carbon and to a rotary kiln comprising said burner pipe. The invention further relates to the use of the burner pipe or rotary kiln for producing activated carbon.

A horizontal pyrolysis furnace has a kiln and two barrels. The two barrels are respectively a processing barrel rotatably disposed in the kiln and a takeover barrel detachably connected with the processing barrel. Each one of the two barrels has a gate assembly and at least one spiral guiding plate. The gate assembly of the processing barrel is mounted on an end of the processing barrel, and extends out from the kiln. The two gate assemblies of the two barrels are detachably connected such that the two barrels are able to rotate synchronously. The at least one spiral guiding plate is fixed on an inner surface of one of the two barrels, and the spiral guiding plates of both barrels have an identical helical direction.

An assembly adapted for incorporation within, and use with, a rotary tubular vessel is disclosed. The assembly includes two oppositely directed finned disks, each defining a central aperture, of a particular size. The assembly includes a collection of longitudinally extending plates that extend between the disks. Upon installation in a tubular vessel, the assembly governs and controls the flow of granular or particulate material through the vessel.

A rotary kiln comprises: a sintering device provided with a cylindrical rotation tube for mixing an input powder raw material while rotating in a horizontal direction; an external heating device for heating the powder raw material input into the rotation tube by heating the outside of the rotation tube; and an internal heating device for stirring and heating the powder raw material input into the rotation tube simultaneously. The internal heating device includes a microwave generation part for generating microwaves; a guide part for guiding the microwaves generated from the microwave generation part into the rotation tube; and a stirring heat generation part coupled to an inner circumferential surface of the rotation tube for stirring the powder raw material input into the rotation tube and simultaneously generating heat when absorbing the microwaves so as to heat the powder raw material.
