Abstract:
1. A burner for a thermal post-combustion device, comprising: a housing; a combustion nozzle, which is disposed in the housing and has a tube through which combustion gas can flow and that has at least one outlet opening for the combustion gas; an eddy apparatus, which is attached to an end region of the housing and through which exhaust gas to be purified can flow; wherein, the combustion nozzle comprises an outer tube having an end region and an inner tube having an end region, with the end regions delimiting an annular outlet gap; and, wherein combustion gas can flow through an interspace between the outer tube and the inner tube, as far as the outlet gap; and, wherein a flow path for the combustion gas has a constriction in a vicinity of the outlet gap; the end region of the outer tube has a portion that tapers conically in a direction of the flow of the combustion gas; the end region of the inner tube has a groove on an outer circumferential surface of the end region of the inner tube; the outer tube and the inner tube are adjustable relative to one another in an axial direction; and, an annular interspace between the housing and the outer tube of the combustion nozzle is located in the field of view of a UV-diode to monitor the combustion process.
