Embodiment Construction

[0059] exist figure 1 A schematic diagram of the device according to the invention is shown in .

[0060] The combustion chamber 1 can be seen, into which the flame 2 is directed.

[0061] The flame 2 is generated at the burner outlet 3 of the burner 4 . In this case, the section of the system which is fluidly situated upstream of the burner outlet is considered to be the cold side of the burner.

[0062] The flame 2 pulsates and thus causes a system-specific resonant gas column pulsation in the combustion chamber and / or in a reaction chamber downstream of this combustion chamber. The educts are fed into this combustion chamber or reaction chamber, processed in an oscillating gas column from the hot gas, and finally the products thus produced are removed from the hot gas stream, for example by means of a hot gas filter, cyclone separator or the like.

[0063] Flame 2 pulsation is a self-excited combustion instability, where the frequency of its self-excited oscillations is ...

Abstract

An oscillating firing system for targeted adjustment / readjustment of amplitudes of oscillations of static pressure and / or hot gas velocity in an oscillating firing system for thermal treatment of materials or materials synthesis includes a burner, with which an oscillating (pulsating) flame is generated, and a combustion chamber (resonator), into which the flame is directed. Usually, a controlled, independent adjustment of the amplitude (oscillation strength) of the pulsating hot gas flow resulting from a self-excited, recoupled combustion instability is not carried out in a vibration combustion or a pulsation reactor and thus also an adaptation of the periodic-transient combustion process to the selected throughput of the reactor (in the case of material treatment / synthesis Eg: the educt feeding rate or the production rate) is not carried out without a simultaneous but undesirable change in other process parameters (treatment temperature, residence time or treatment time) and thus the material properties produced. Upstream of the burner outlet an oscillation volume is inserted into the supply lines leading to the burner through which oscillation volume air, fuel or fuel-air mixture can flow. Preferably, the size of the oscillation volume may be adjustable. Thus, it is possible to change the amplitude of oscillation.

Description

technical field [0001] The invention relates to a method for targeted adjustment of the oscillation amplitude (oscillation intensity) of an oscillating combustion process in an oscillating combustion device (pulsation dryer, pulsation combustion chamber, pulsation reactor) in a plant for material processing or material synthesis method, the oscillating combustion device has at least one burner, to which fuel and / or air is fed through at least one duct towards the burner outlet, in the oscillating combustion device there is a pulsating flame formed on the burner outlet, the pulsating The flame burns in the combustion chamber, the oscillating combustion device has at least one resonant gas column (for example in the combustion chamber or in a resonance tube), the gas column is transported to the material to be processed, the invention also relates to a corresponding for A device for implementing the method and a corresponding application method. Background technique [0002] ...
