Abstract (en)
The burner (1) has a mixture forming zone (3) for forming a fuel air mixture (11), and a burner output (2). An acceleration zone (9) is arranged between the mixture forming zone and the burner output for increasing the speed of the fuel air mixture, where the acceleration zone has a flow body (10). The acceleration zone is arranged in a jet pipe (8) that is designed as a diffuser (12) in an area extending from the flow body till to the burner output. The flow body is arranged in an area of a center axle of the jet pipe, and an opening for injecting air and/or fuel into the jet pipe. An independent claim is also included for a method for reducing self-induced flame vibrations in a burner.
Abstract (de)
Es wird ein Brenner (1) zur Verfügung gestellt, der eine Gemischbildungszone (3) zur Ausbildung eines Brennstoff-Luft-Gemisches (11) und einen Brennerausgang (2) umfasst. Zwischen der Gemischbildungszone (3) und dem Brennerausgang (2) ist eine Beschleunigungszone (9) zur Erhöhung der Geschwindigkeit des Brennstoff-Luft-Gemisches (11) angeordnet. Die Beschleunigungszone (9) umfasst mindestens einen Strömungskörper (10).
