Abstract: The fuel jet (105) produced by the fuel nozzle (104) has an emission angle which corresponds approximately to the adjustment angle of the components (101,102) forming the spin producer (100) in relation to the axis of the burner or of the combustion chamber. The spin producer comprises a number of circular blades. Use - As a burner for a heat producer.

Abstract: The mixing burner has inter-stacking parts. The longitudinal axis of symmetry (101b,102b) of each of the parts (101,102) is staggered in position so that the adjacent walls of the parts in their longitudinal direction form tangential air inlet slits (119,120) for combustion air (115) to flow into the hollow conical interiors (114) of the parts. At least one fuel nozzle (103) is contained in the conical interior and is staggered in position in relation to the start of the cone (125) induced by the parts of the premixer burner (100). Further fuel nozzles (117) are near the tangential air inlet slits.

Abstract: In a burner which essentially comprises a swirl generator (100) for a combustion-air flow (115) and means for injecting a fuel into the combustion-air flow (115), a mixing section (220) is arranged downstream of the abovementioned swirl generator. This mixing section (220) has inside a first part (200) of the section a number of transition passages (201) which run in the direction of flow and ensure the smooth passing of the flow (40) formed in the swirl generator (100) into a tube (20) arranged downstream. The outlet plane of this tube (20) to the combustion chamber (30) is formed with a breakaway edge which serves to stabilize and enlarge a backflow zone (50) forming downstream.

Abstract: The burner is designed so that downstream of the fuel injector at least one sensor (400) is arranged for determining a block-back of the flame (80) from the combustion chamber (30) in the inside of the burner, fuel regulation is activated. The fuel supply to the flame is reduced at least temporarily and the fuel amount to the pilot burner is increased simultaneously to maintain a constant turbine output.

Abstract: The burner has a mixer section and a swirl generator. The mixer section (220) is positioned downstream from the swirl generator (100) and has, within a first part of the section (200) transfer ducts (201) running in the direction of flow for transmitting a current (40) formed in the swirl generator into a pipe situated downstream from the transfer ducts. The outlet plane of the pipe to the combustion chamber (30) has a break edge (A) for stabilising and enlarging a reverse current zone (50) formed downstream. The number of transfer ducts in the mixed section matches the number of art currents formed by the swirl generator. The pipe situated after the transfer ducts has openings (21) for injecting an air current into the pipe.

Abstract: In a burner for operating a combustor, the former consists essentially of a rotation generator (100), a transition piece following the rotation generator, and a mixing pipe following this transition piece. Transition piece and mixing pipe form the mixing section (220) of the burner and are located upstream from a combustion chamber (30). In the lower part of the mixing pipe is located a pilot burner system (300) which creates, among other things, a stabilization of the flame front, in particular in the transient load ranges, while minimizing pollutant emissions. A sensor (400) installed in the burner detects a flashback of the flame (80), whereupon the fuel quantity of this flame is at least temporarily reduced and at the same time the fuel quantity for the pilot burner is increased in such a way that the total fuel quantity and thus the turbine output remains constant. This measure prevents a destruction of the burner.

Abstract: Bei einem Brenner für einen Wärmeerzeuger, der im wesentlichen aus einem Drallerzeuger (100a) für einen Verbrennungsluftstrom (115) und aus Mitteln zur Eindüsung eines Brennstoffes in diesen Verbrennungsluftstrom besteht, ist stromab des erwähnten Drallerzeugers eine Mischstrecke (220) angeordnet. Diese Mischstrecke weist innerhalb eines ersten Streckenteils (200) eine Anzahl von in Strömungsrichtung verlaufenden Uebergangskanälen (201), welche die nahtlose Ueberführung der im Drallerzeuger (100a) gebildeten Strömung (40) in ein nachgeschaltetes Rohr (20) sicherstellen. Eine zur Eindüsung eines Brennstoffes kopfseitig und auf der Brennerachse (60) angeordnete Düse (103) ist gegenüber dem Anfang des Drallerzeugers um eine Strecke stromauf versetzt.
