<p>The burner device has a combustion chamber (6) at a mixing area (4), and a mixer is burnt in the combustion chamber in the form of a flame (8) to an exhaust gas. A measuring unit (12) detects a parameter, which represents a criterion for the presence of the flame. The measuring unit is arranged upstream to the exhaust gas flow in an area, where the exhaust gas flow provides excess oxygen, which is required by a combustion air (2). The measuring unit is held by a holder (13), and the combustion air is directed to the measuring unit before reaching the flame.</p> |
