Abstract:
The pyrogasification plant (1) comprises a reaction chamber (2) having a base frame (3) supporting a lateral wall (4, 5, 6) wherein a material to be pyrogasified (M) can be introduced for being transformed into syngas (S), tar (T) and char (C), wherein the lateral wall (4, 5, 6) comprises an external supporting structure (4) supporting an internal metal cartridge (5), with a substantially tubular shape and having an upper extremity (5a) and a lower extremity (5b), both of which are open, the material to be pyrogasified (M) crossing the internal metal cartridge (5) from the upper extremity (5a) to the lower extremity (5b) remaining contained by the internal lateral surface of the internal metal cartridge (5).
Abstract:
A method and plant for thermal treatment and chemical transformation of waste comprising natural and synthetic carbonaceous materials for generation of a fuel gas for further use is described. Pyrolysis gas and solid waste from a thermolysis and pyrolysis reactor (40), is further processed to produce a fuel gas having a substantially stable WOBBE index.
Abstract:
The present invention relates to a novel method for pyrogasification of organic waste. The inventive method uses a vertical furnace (1) filled with metal masses in the form of metal toroids (2), previously heated to a high temperature (500 to 1100 °C), and organic matter (3) to be pyrolysed. The method also involves a furnace (9) suitable for heating the toroids (2) conveyed by an Archimedes screw (18) driven by a gear motor (19), as well as a separator (11) for recovering the mineral residue (12), the toroids (2) and the residue (12) being separated using a screen (14) and an Archimedes screw (15) driven by a gear motor (16). The inventive method can be used for treating all products which contain organic matter, whether from biomass and thus considered renewable energy, or not from biomass.
Abstract:
Methods and apparatus for treating waste are provided. Waste is converted in an arc plasma-joule heated melter system (21) utilizing one or more arc plasma electrodes (27) and a plurality of joule heating electrodes (24). The arc plasma electrode(s) (27) can be configured for operation utilizing the AC or DC power, or for switching between AC and DC power. The arc plasma electrodes (27) can also be configured for independent arc voltage and arc current control. The joule heating circuits are configured for simultaneous operation with the arcing electrodes, but without detrimental interaction with the arcing electrodes. The systems provide stable, non-leachable products and a gaseous fuel. The gaseous fuel can be utilized in a combustion or non-combustion process to generate electricity.
Abstract:
The present invention refers to a method and an equipment for pyrolytic treatment of organic material, comprising a supply storage (1) receiving the organic material to be treated, a number of containers (2) with meshlike walls, each to be charged with a batch of said organic material, a horizontal reactor (3) with a charge gate (4) in one end and a discharge gate (5) in the opposite end, the interior of the reactor being divided by means of internal gates (15, 16, 17, 18) into at least a heating chamber (7), a pyrolysis chamber (8), and a cooling chamber (10), as well as a recovery storage (11) for a solid pyrolytic rest of the organic material, i.e. the pyrolytic coke, the pyrolysis chamber being provided with an outlet pipe (12) for generated pyrolytic gas terminating in a fractionating condenser (13), said condenser being provided with an outlet (13a, 13b, 13c) for each liquid fraction and an outlet pipe (13d) for uncondensed pure pyrolytic gas, which outlet pipe terminates in a gas tank (14).
Abstract:
Die Erfindung betrifft ein Verfahren und eine Anlage zur thermischen Behandlung von Abfallstoffen und/oder -fraktionen, in welcher die Abfallstoffe und/oder -fraktionen thermisch inertisiert werden, wobei die Abfallstoffe und/oder -fraktionen auf geschlossenen, z.B. durch Schlitze gebildete, Gasaustauschöffnungen (15, 16) in den Wandungen (17, 18; 19, 20) aufweisenden Transporteinheiten (6) in einen, gegebenenfalls mit einer zusätzlichen Frischluftzufuhr (2) versehenen, herkömmlichen Brennofen (1), z.B. für Keramik, Ziegel oder andere Tonwaren, einbringbar sind.
Abstract:
Zur zirkulierenden Wirbelschicht gehört eine Wirbelbrennkammer (1), welcher man sauerstoffhaltiges Fluidisierungsgas zuführt. Aus dem oberen Bereich der Wirbelbrennkammer wird ein Gas-Feststoff-Gemisch mit Temperaturen von 800 bis 1400°C abgezogen und einem Abscheider (13) zugeführt. Aus dem Abscheider zieht man heiße Feststoffe ab und speist mindestens einen Teil (9a) der Feststoffe in einen außerhalb der Wirbelbrennkammer angeordneten Mischer (8) ein. Diesem Mischer führt man auch Abfallstoffe (7) zu und vermischt sie mit den eingespeisten heißen Feststoffen, wobei ein Feststoffgemisch und Pyrolysegas gebildet werden. Mindestens einen Teil des Feststoffgemisches (10) leitet man in die Wirbelbrennkammer. Das Pyrolysegas (15) kann zum Beispiel in die Wirbelbrennkammer geleitet oder in einer separaten Brennkammer (16) verbrannt werden.
