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).
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.

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:
Le dispositif permet d'alimenter en boue une enceinte sous pression (12). Une couronne mobile (10) comprenant des passages radiaux (18) est montée dans l'enceinte à glissement libre (12). Le moyeu de la couronne mobile est relié à un organe d'entraînement (42) et à un organe d'alimentation en boue (16) s'étendant au travers de l'enceinte (12). Du gaz sous pression est amené dans l'enceinte de manière à envelopper sensiblement la couronne mobile dans une bulle de gaz.
摘要:
L'appareil est concu pour regler la vitesse d'alimentation d'un container sous pression (4) en materiau pulverise. L'appareil est egalement capable de compenser les variations de permeabilite du materiau. Un rotor (2) qui comprend des coulees (16) de commande de la distribution de la section le long des coulees est situee dans le container pressurise. Le moyeu du rotor (6) est relie a des moyens d'entrainement (8) et des moyens d'alimentation du materiau qui s'etendent au travers de la paroi du container (4). Une canalisation (32) de commande de la pression le long des coulees (16) par injection de gaz est en communication avec une chambre (25) entre les sections de la coulee pour commander la pression du gaz en ce point. La canalisation de commande de la pression du gaz (32) est connectee a une source de gaz sous pression et a un systeme de commande (36) exterieur au rotor.
摘要:
Methode et appareil pour alimenter en continu un container a haute pression en materiau pulverise (2). Un rotor (12) est situe dans le container a haute pression (2). Le materiau pulverise est amene depuis une tremie d'alimentation par l'intermediaire d'un tube d'alimentation stationnaire (4) vers une chambre a tourbillon verticale mise a l'event (10) jusqu'a une pluralite de coulees a deux etages (32) montees dans le rotor (12). Des orifices de commande (38) en aval des coulees mesurent l'ecoulement du charbon au travers des coulees (32).
摘要:
Method and apparatus are shown for the continuous feeding of pulverized material to a high pressure container. A rotor (1) is located within the high pressure container (2). The pulverized material is fed from a feed hopper (4) through a stationary feed pipe (3) to a vented spin-up chamber (8) to a plurality of two-stage sprues (9) mounted in the rotor. Control orifices (17) downstream from the sprues meter the flow of coal through the sprues. Previous feeders tried to keep the material in a fluidized state and avoid a compacted plug form of flow. The prevent feeder makes use of compacted plug formations in the sprues as seals against high pressure gas.
摘要:
Apparatus is shown for adjusting the feed rate of pulverized feed material into a pressurized container (4). The apparatus also has utility for compensating for variations in the permeability of the feed material. A rotor (2) that includes sprues (16) with provision for controlling the pressure distribution along the sprues is located within the pressurized container. The rotor hub (6) is connected to a drive means (8) and a material supply means which extend through the wall of the container (4). A line (32) for controlling pressure along the sprues (16) by gas injection is connected to a chamber (25) between sections of the sprue for controlling gas pressure at that point. The gas pressure control line (32) is connected to a pressurized gas source and a control system (36) external to the rotor.
