Title (EN) APPARATUS FOR THROTTLING A DRY PULVERIZED SOLID MATERIAL PUMP
(FR) APPAREIL DE REGLAGE D"UNE POMPE POUR MATERIAUX SOLIDES PULVERISES SECS
Abstract: front page image
(EN)A kinetic extruder for feeding pulverized coal from an atmospheric pressure hopper to an elevated pressure reactor vessel. In order to overcome the disadvantage of not being able to vary the feed rate of the pulverized coal in an efficient manner apparatus capable of controlling and adjusting the amount of material fed from a low pressure container into a pressurized container is employed. The apparatus comprises a rotor (2) with a plurality of generally-extending sprues (16), a hub (6) connected to a drive (8), throttleable control orifices (28) and a material supply (18) extending into the hub for feeding pulverized material thereto. Apparatus (26, 32) for controlling the gas pressure at the entrance to the control orifice (28) is connected to a pressure regulator and control system (36).
(FR)Une machine a extruder cinetique sert a l"alimentation en charbon pulverise depuis une tremie sous pression atmospherique d"un reservoir ou container d"un reacteur sous pression elevee. Afin de resoudre le probleme que pose le reglage efficace du debit de charbon pulverise, on utilise un appareil capable de commander et de regler la quantite de materiaux provenant d"un container a basse pression et alimentant un container pressurise. L"appareil comprend un rotor (2) avec une pluralite de coulees (16), un moyeu (6) connecte a un moteur d"entrainement (8), des orifices de commande reglables (28) et une alimentation de materiaux (18) s"etendant dans le moyeu pour l"alimentation en materiaux pulverises. L"appareil (26, 32) de commande de la pression des gaz a l"entree de l"orifice de commande (28) est connecte a un systeme regulateur et de commande de la pression (36).
