The invention relates to a biochar production plant, a combustion chamber, and a method of operating same. The plant comprises a fuel hopper, a fuel delivery system, a combustion stage, and a post combustion stage. The post combustion stage includes a generator; a biochar removal stage and a flue gas scrubber. The combustion stage comprises a combustion chamber having an active fluid biochar bed comprising a pair of oscillating plates, one on top of the other; an air injection ring positioned above and spaced apart from the pair of oscillating plates; a biochar shelf, below and surrounding the active fluid biochar bed, positioned to receive biochar falling from the pair of oscillating plates, and means to transfer the biochar from the biochar shelf to a biochar outlet. There is provided at least one sensor operable to measure the depth of the active fluid biochar bed on the oscillating plates and a controller responsive to the sensor. The controller is operable to control the depth of the active fluid biochar bed and the temperature of combustion by controlling the oscillating plates and the air delivered into the combustion chamber. In this way, the construction is very simple, cost effective and has accurate combustion control leading to a quality biochar end product.

An apparatus for thermal processing of waste having organic and inorganic components comprises at least a treatment station, a cooling station and a treated material-removal station, and at least three crucibles. The treatment station is adapted to thermally treat the organic components and/or inorganic components located in a given one of the crucibles located at the treatment station. The so-treated components in this given crucible are adapted to then be cooled at the cooling station, before the treated components located in the given crucible are removed therefrom at the treated material-removal station. The three crucibles are mounted on a turntable so that the three crucibles are each at one of the stations, before synchronously all moving to each crucible's next station.

Disclosed is an apparatus for combusting recyclable or waste material. The apparatus comprises a cylindrical combustion chamber. The chamber comprises a first inlet in a side wall. The first inlet is in communication with a blower and an ignition means. The chamber also comprises a second inlet in a first end wall or a side wall. The second inlet is in communication with a source of recyclable or waste material. The chamber also comprises an outlet in a second end wall on a central axis of the chamber. The longitudinal axis of the first inlet is offset from the central axis of the chamber. In use, the blower forces the recyclable or waste material to circulate around the inside of the chamber.

This present invention relates to a eco-friendly ultra-high temperature thermal decomposition system for waste-to-energy, where its thermal decomposition chamber made with special castable mixture maintains the ultra-high temperature above 850? C. and ten (10) layers of air curtains made by a double-layered air-curtain maker installed at the center of the thermal decomposition chamber allows the input materials to be completely decomposed without any auxiliary fuel and air pollutants to be completely decomposed by trapping them inside the thermal decomposition chamber with ultra-high temperature above 850? C. for more than two (2) seconds of residence time, as well as its two (2) layers of oil nozzles, central oil nozzles and lower oil nozzles, installed on the inner wall of the thermal decomposition chamber, each installed to aim the central part and the bottom part of the thermal decomposition chamber, evenly spraying the auxiliary fuel when necessary so the input materials with different conditions, sizes, and hydration level, are completely decomposed; furthermore, its outer shredder, installed at the left side of the thermal decomposition chamber, improves its treatment efficacy by homogenizing the input materials with different conditions, sizes, and hydration level, prior to being fed into the thermal decomposition chamber, with a screw conveyor connecting the outer shredder and the thermal decomposition chamber automatically feeding the input materials, as well as its inner shredder installed at the bottom part of the thermal decomposition chamber shreds the ash and the input materials that are not being decomposed yet piled up at the bottom of the thermal decomposition chamber so the screw conveyor connecting the inner shredder and the thermal decomposition chamber can re-input such materials back to the thermal decomposition chamber, thus even the ash is also completely decomposed; moreover, its thermal generation modules, installed in the thermal generation chamber around the thermal decomposition chamber and on the upper cover of the thermal decomposition chamber, effectively collect the waste heat generated from thermal decomposition process to generate electricity while the waste heat is also used to generate steam via the steam chamber installed on the upper cover of the thermal decomposition chamber, where such steam is sent to separately composed boiler and steam turbine via steam pipe to generate further electricity; and lastly, its dust collector and the monitoring device are located at the right side of the thermal decomposition chamber with their collecting holes at the top part of inner wall of the thermal decomposition chamber to col

An apparatus, a system, and a method for heat treating a moisture-containing or water-laden material are provided. The heat treatment can be drying for dehydration, gasification, or full carbonization. The system comprises a feeding mechanism, and a rapid compression unit (RCU) apparatus having a screw, a barrel, and one or more flow disrupters. The system can further include a reflux condenser, an aftercooler stage, a second condenser for particle filtering, and an exit mechanism. The one or more flow disrupters are located on an inner surface of the barrel and project into the passageway created by the screw and the barrel. The screw is sized to fit within the barrel such that flow disrupter does not contact the screw. The one or more flow disrupters cause the water-laden material to fold over onto its self, thereby, allowing for the occurrence of more uniform drying.
