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 for treating a product with microwaves includes a treatment chamber, in which the product can be transported along a transport path in a transport direction through the treatment chamber, and a microwave radiation device arranged in the treatment chamber, by means of which microwaves coupled into the microwave radiation device can be radiated, which act on the product, wherein the microwave radiation device includes at least one coaxial conductor which protrudes into the treatment chamber, or is arranged therein, with an electrically-conductive internal conductor and an electrically-conductive external conductor, wherein the external conductor, arranged coaxially, surrounds the internal conductor in a spaced manner and includes at least one opening, which enables an emission of microwaves from the coaxial conductor through the opening on to the product.

Abstract: A device fir treating a product with microwaves has a treatment chamber in which the product can be conveyed along a transport track in a transport direction through the treatment chamber, and has a microwave-emitting apparatus, which is arranged in the treatment chamber and by which microwaves coupled into the microwave-emitting apparatus can be emitted, which microwaves impinge upon the product. The microwave-emitting apparatus has at least one coaxial conductor, which protrudes into or is arranged in the treatment chamber and which has an electrically conductive inner conductor and an electrically conductive outer conductor, the outer conductor surrounding the inner conductor at a distance therefrom and in coaxial arrangement and having at least one opening, which enables the emission of microwaves through the opening from the coaxial conductor onto the product.

Abstract: A magnetic field generation apparatus is provided for a magnetron including a permanent magnet arrangement and a magnetic field conductor device. The magnetic field conductor device has a diverting element. The diverting element, which includes a plurality of rectangular diverting segments, is arranged detachably on the magnetic field generation apparatus during maintenance work in order to deflect a magnetic field generated by the permanent magnet arrangement away from further components of the magnetic field generation apparatus and components of the magnetron. A magnetron includes a magnetron tube and such a magnetic field generation apparatus. In a method for replacing an old magnetron tube of such a magnetron with a new magnetron tube, the diverting element is arranged on the magnetic field generation apparatus, and the old magnetron tube is removed from the magnetron and replaced with the new magnetron tube in order to then remove the diverting element again.
