Abstract

A method and plasma-generating device for generating a plasma flame with a plasma combustion gas blown in a plasma flame direction from a plasma combustion chamber through a plasma flame opening. The plasma combustion chamber is arranged in a cavity resonator to which microwave energy is supplied and generates plasma. A swirling gas is blown into the plasma combustion chamber by a swirl-generating device to generate a swirling gas shell which surrounds the plasma flame and shields a plasma combustion chamber wall composed of a dielectric solid material. The plasma combustion chamber wall protrudes along the plasma flame direction beyond the cavity resonator in both directions and is fixed in a plasma combustion chamber wall holder a distance from the cavity resonator. The plasma combustion chamber wall holder has at least one holder cooling cavity through which a coolant flows.

Abstract

The invention relates to a method for treating products in a microwave treatment device and to a microwave treatment device. The microwave treatment device has at least one treatment chamber and at least two coupling elements. The coupling elements are designed to couple microwaves into the treatment chamber during a treatment step (2) so that a product arranged in the treatment chamber is treated by the microwaves propagating in the treatment chamber. In a characteristic ascertaining step (3), characteristics are detected, wherein a check is carried out on the basis of the characteristics in a checking step (4) in order to determine whether an actual treatment result corresponds to a specified target treatment result.

Abstract

A device (1) for combining or splitting microwaves has a combined-wave guide (2), in which microwaves with a wavelength suitable for the combined-wave guide (2) can propagate in a combined-wave guide propagation direction (7). The device (1) has at least two single-wave guides (4) which open into a coupling region (3). Via the coupling region (3), microwaves can be transferred between the single-wave guides (4) and the combined-wave guide (2). At the opening into the coupling region (3), the single-wave guides (4) each define a single-wave guide propagation direction (10) for the microwaves propagating through the single-wave guides (4), which single-wave guide propagation direction differs from the combined-wave guide propagation direction (7). The single-wave guide propagation directions (10) of all single-wave guides (4) extend perpendicularly to a common coupling plane (12). The combined-wave guide propagation direction (7) extends in or parallel to the coupling plane (12). The at least two single-wave guides (4) open into the coupling region (3) in such a manner that a phase angle difference error of microwaves propagating through the at least two single-wave guides (4) into the combined-wave guide (2) is, at a transition end (14) of the coupling region (3), less than 5% of the wavelength and preferably less than 2% of the wavelength of the propagating microwaves.

Abstract

The invention relates to a method for monitoring the operation of a magnetron (1) with a temperature detection device (3). The temperature detection device (3) can initiate an interruption of the operation of the magnetron (1) if a switch-off temperature value detected by the temperature detection device (3) is exceeded. According to the invention, a temperature value is detected and transmitted to an analysis device (4) continuously or in time intervals by means of the temperature detection device (3) during the operation of the magnetron (1), and a controller (5) of the magnetron (1) can be triggered by the analysis device (4) to interrupt the operation of the magnetron (1) if the detected temperature value lies above the switch-off temperature value. The controller (5) of the magnetron (1) is triggered by the analysis device (4) in order to reduce the operating power of the magnetron (1) if the detected temperature value exceeds a warning temperature which lies below the switch-off temperature. The temperature detection device (3) can have a temperature sensor and a control temperature sensor so that the temperature value detected by the temperature sensor can be compared with a control temperature value detected by the control temperature sensor continuously or in time intervals, and a differential temperature value can be formed.
