Abstract: The present disclosure relates to a vortex chamber comprising a cavity elongating along a central axis and a swirl generator. The swirl generator comprises a plurality of swirl channels configured for introducing a gas flow into the cavity as a vortex flow about the central axis, each swirl channel comprising a channel entrance and a channel exit. The swirl generator further comprises a gas redistribution chamber comprising one or more main gas supply inlets for receiving a gas, a distribution channel configured for distributing the gas received from the one or more main gas supply inlets to the channel entrances of the swirl channels, and one or more blocking walls configured for blocking and unblocking one or more entrances of the plurality of swirl channels. The vortex chamber is further configured for relatively rotating the channel entrances of the swirl channels with respect to the one or more blocking walls from a first angular position to at least a second angular position and vice versa, and wherein when in the second angular position the one or more blocking walls block a larger number of channel entrances than when in the first angular position.

Abstract: The present disclosure relates to a device for gas conversion comprising a plasma reactor and a chamber configured for receiving a gas flow of converted and unconverted feed gas evacuated from the plasma reactor. The chamber comprises a supply throughput for filling the chamber with solid reactant material so as to form the fixed bed of solid reactant material, and at least one gas exhaust window for extracting a product gas. The device for gas conversion further comprises a silo for storing a stock of the solid reactant material and a connecting tube connecting a bottom opening of the silo with the supply throughput of the chamber. The silo and the connecting tube are configured such that, when the device is in operation and solid reactant material is being depleted in the chamber, a flow of solid reactant material from the silo to the chamber is induced so as to maintain the chamber filled with solid reactant material, and wherein the flow of solid reactant material from the silo to the chamber is induced by a gravitational force or at least partly by a gravitational force. The present disclosure also relates to a method for gas-conversion.
