A method and a device for reliably preventing undesired flashback or excessive separation/extinction of a pulsating flame for use in pulsed combustion reactors or pulsation reactors for thermal material treatment or thermal material synthesis is disclosed. The invention makes it possible to operate pulsed combustion reactors or pulsation reactors with thermal material treatment at markedly greater amplitudes of an oscillation of a hot gas flow in the reactor, and to improve the properties of the thermally treated/thermally synthesized material, and to markedly increase the throughput rates of the reactor (reactor capacity), and thus to reduce production costs in comparison to other thermal methods/apparatus for material treatment, and hence to make the pulsed combustion reactor technology or pulsation reactor technology more competitive. According to the invention, the invention uses a swirl burner to generate a swirl-stabilized flame, an essentially conical diffuser being connected downstream of the burner.

The invention relates to a device and a method for thermal treatment of a raw material in an oscillating hot gas flow of a pulsation reactor, comprising a burner, which is supplied with a mass flow, via at least one pipeline, for forming at least one flame, which produces the oscillating hot gas flow, wherein the flame is arranged in a combustion chamber, and wherein a reaction chamber follows the combustion chamber downstream of the combustion chamber. In order to be independent of the dimension of the device, it is proposed to provide the mass flow that is supplied to the flame with an externally impressed pulsation. The combustion chamber and/or the reaction chamber can then be varied in geometry to avoid resonances.

The invention relates to a pulsed combustor assembly (A) for dehydration and/or granulation of a wet feedstock, in particular a viscous feedstock such as a feedstock containing natural fibers, sugars and/or vegetable starches, comprising a combustion chamber (16), at least one fuel supply line (23), at least one air supply line (26), and at least one pulsed air generator, wherein the pulsed air generator is connected to the air supply line (26) for generating at least a first pulsed air stream with a pulse frequency f1 entering the combustion chamber (16).

A variable residence time drying system for moist material includes a valveless pulse combustor and a drying chamber. The drying chamber includes a lower sidewall with an upward expanding configuration that defines a lower inverted partial cone, an upper sidewall with an upward contracting configuration, a lifting rotor disposed within the lower inverted partial cone to suspend material being dried within a shear/drying zone, an opening through which moist material is fed into the drying chamber, and an exit located at a top portion of the drying chamber through which dried material exits the drying chamber. The valveless pulse combustor produces drying gas and sonic vibrations that are introduced tangentially into the shear/drying zone. One or more cyclones receive dried material and collect small particles. The lifting rotor may rotate in a direction counter to a direction in which the heated drying gas is introduced into the drying chamber.
