摘要:
The present inventive concept relates to a cyclone gasifier comprising: a gasification chamber, a first and a second inlet, and a syngas exit pipe arranged at least partly inside the gasification chamber. The first inlet is arranged and configured to inject a first mixture of oxidant and particulate fuel into the gasification chamber such that a first swirling flow of the first mixture is established and allowed to propagate through at least a part of the gasification chamber. The second inlet is arranged and configured to inject a second mixture of oxidant and particulate fuel into the gasification chamber such that a second swirling flow of the second mixture is established and allowed to propagate through at least a part of the gasification chamber. The second swirling flow is at least partly offset in its propagation compared to the first swirling flow.
摘要:
Process and device for introducing solid particles, e.g. particulate coal, into a gas-containing vessel (1), using a centrifugal coal pump comprising a feed inlet (17) and a rotor (5). The rotor (5) is surrounded by a second gas of lower density than the vessel gas, i.e. of lower pressure and/or lower molecular weight, in order to reduce friction. Low pressure hydrogen is preferred. Means (14, 14', 8, 18) to reduce leakage are provided for.

摘要:
Process for partial oxidation of a hydrocarbon gas or liquid, comprising the steps of partial oxidation and removal of soot by forming a slurry comprising water and carbon from the gaseous oxidation product, and separating part of the water from the slurry to obtain a soot composition comprising less water, wherein the separation is performed by means of a decanter centrifuge.
摘要:
Un appareil permet d'augmenter sensiblement le taux d'alimentation d'un matériau pulvérisé dans un récipient pressurisé. L'appareil comprend un rotor (10) monté à l'intérieur du récipient pressurisé. Le matériau pulvérisé est introduit dans une chambre annulaire (30) définie par le centre du rotor (10). Une pluralité de couronnes mobiles (90) sont montées à l'intérieur de la chambre annulaire (30) pour transmettre un couple au matériau pulvérisé.
摘要:
A gasification reactor apparatus (10) comprising a gasification vessel (12), a gas-fired combustion chamber (70) and a combination fan and cyclone unit (20) in an upper part (12') of the vessel (12) with two functions: first, the fan (62, 64) impels incoming feedstock (14, 14') centrifugally into contact with the hot inside surface of the vessel to produce rapid onset of gasification. Second, the unit (20) exerts a cyclonic motion on the product gas causing outward separation of particulate matter from the gas, which passes to the outlet via a path through the middle of the vessel (12).
摘要:
Method and apparatus are shown for the continuous feeding of pulverized material to a high pressure container (2). A rotor (12) is located within the high pressure container (2). The pulverized material is fed from a feed hopper through a stationary feed pipe (4) to a vented spin-up chamber (10) to a plurality of two-stage sprues (32) mounted in the rotor (12). Control orifices (38) downstream from the sprues meter the flow of coal through the sprues (32).
