Abstract:
A downdraft gasifier is disclosed. The gasifier has a biomass feeding unit, a combustion chamber, and a separator unit. The biomass feeding unit accepts raw biomass materials and selectively feeds the materials into the combustion chamber. The combustion chamber provides means to induce pyrolysis, tar cracking, and char gasification of the raw biomass materials to produce gases and ash. The separator unit accepts the gases and ash from the combustion chamber and separates the gases from the ash.
Abstract:
Kleinstfeuerungsanlage für biogene Fe st brenn Stoffe Die Erfindung betrifft eine mit Festbrennstoffen automatisch beschickte Verbrennungsapparatur, insbesondere zur Beschickung mit biogenen Festbrennstoffen für die Erzeugung von Wärme und/oder Produktgasen wobei der Brennstoff über eine Beschickungseinrichtung (1) einem zylinderförmigem Reaktor zugeführt wird, in dem sich eine Brennstoffauflage befindet, auf dem der Festbrennstoff aufgrund von. Temperatureinwirkung und der Zuführung von Primärluft durch Pyrolyse- und Vergasungsprozesse in gasförmige Reaktionsprodukte umgewandelt wird, welche nach unten durch ein Rohrstück mit Einrichtungen zur Erzeugung von Turbulenz (8) geleitet wird und in einem weiteren zylinderförmigen Reaktor (7) mit größerem Querschnitt als (4) durch Zufuhrung von vorgewärmter Sekundärluft (3) möglichst vollständig oxidiert werden. Als Wärmequelle für die Erreichung notwendiger Zündtemperaturen und die Ausbildung eines Glutbettes dient ein vertikaler elektrisch betriebener Klapprohrofen (5).

Abstract:
In a method and an installation for thermally gasifying solid fuel, such as biomass fuel, a layer of the solid fuel forms a fixed bed (13), which is heated so as to form volatile fuel components by pyrolysis. At least part of said volatile components are then caused to move upwardly into a reactor chamber (15), which is defined above the layer of solid fuel, and at least one reactant, preferably comprising oxygen, is fed into said reactor chamber, so that the reactants are contacting and chemically reacting with the volatile components in the reactor chamber. The chemical reaction taking place is preferably an exothermic process so that hot gaseous products are generated and tar components are decomposed. The hot gaseous products from the reactor chamber (15) are discharged through the layer (13) of solid fuel, which are thereby heated so as to maintain the pyrolysis process and so as to gasify char in the fuel bed.
Abstract:
A downdraft gasifier (1) has an oxidant inlet (3), a biomass injector (2), a grate (9), a gas exit port (7), and an ash removal system (11). A sensor (10) maintains the height of the bed and a rotating paddle (5) maintains the top of the bed (4) at an even height. The grate arrangement (9) is preferably a sliding grate arrangement which actively moves ash material through the grate. An in-bed oxidant distributor (6) injects oxidant within the bed.
Abstract:
Изобретение может быть использовано для переработки бывших в употреблении мото-, авто-, тракторных покрышек и других отходов органического происхождения. Установка для переработки углеродсодержащего сырья содержит корпус с обшивкой 17, разделённый на камеру газогенерации 21 со сводом 1 и двумя загрузочно- выгрузочными люками 18, 19, и камеру сгорания, выполненную из трёх автономных камер 5, 6, 7, расположенных друг возле друга и связанных между собой отверстиями. Камера газогенерации 21 расположена над камерами сгорания 5, 6, 7 и отделена от них плитой 14. Каждая из автономных камер 5, 6, 7 имеет, по меньшей мере, одно отверстие для подачи воздуха 8, 13, 9. Причём отверстия 8, 9 в боковых камерах 5, 7 расположены в их боковых стенках под углом к ним, а отверстие 13 в центральной камере 6 расположено прямо, в дверце 12, которой оснащена камера 6. Изобретение позволяет создать вихревые потоки разной скорости и температуры, в результате чего повышается мощность установки, а также обеспечить экологически чистую утилизацию отходов.
