Description/Abstract This patent describes an apparatus for the pneumatic injection of pulverulent materials into a pressurized vessel, comprising a storage silo, a series of metering means for extracting the pulverulent material from the distribution silo, pneumatic conveying pipes connecting each of the metering means to the pressurized vessel, and also means for the automatic transfer of the pulverulent material from the storage silo.^ It includes: two intermediate silos, each intermediate silo is connected by first automatic valve means upstream to the storage silo and by second automatic valve means downstream to the distribution silo; pressurizing circuit means connecting a source of inert gas under pressure through third automatic valve means to each of the intermediate silos; and wherein the two intermediate silos are alternately connected to the storage silo and to the distribution silo to enable substantially continuous transfer of pulverulent material from the storage silo to the distribution silo.
