Definitions
- the invention relates to a burner for the oxidation of liquid fuel with air, according to the preamble of claim 1, in training as Dual fuel burners.
- Such a burner is also known from DE 195 39 246 A1.
- the object of the invention is a burner of the generic type so kind of expanding that it while maintaining its positive burning properties for operation with liquid and gaseous fuel suitable is.
- the solution according to the invention is that an additional channel for the gaseous fuel is led into the interior of the atomizer lip and upstream of the atomizer edge, i.e. that for fuel processing ultimately authoritative position, in the primary and / or in the secondary Canal opens.
- the additional channel can largely be designed as desired and in sections from a large number of interacting individual channels (e.g. holes) exist.
- the gas admixture near the atomizer edge ensures a homogeneous mixing of the fuel components with sufficient Cooling of the burner - without the flame front retracting the air ducts.
- a burner arrangement that can be operated with either liquid or gaseous fuel is already known from DE 28 20 702 C2. This points in Center a mixing ring with a mixing surface, which with a Airflow a spray of liquid fuel can be supplied and from which the fuel-air mixture enters the mixing ring. Gaseous fuel can be introduced into an air stream from the underside of the mixing ring. It is not planned to operate both fuels together.
- the two-fuel burner 1, the longitudinal center axis of which is designated X, is fed with liquid fuel F via the atomizing nozzle 2.
- the fuel emerges from the atomizing nozzle 2 in the form of a divergent spray cone 13 and meets the inner surface of an annular one concentric with respect to the X axis Atomizer lip 3.
- a downstream migrating lip forms on this Fuel film 14, which on the atomizer edge 4 as a result of there prevailing air flow conditions in a fine, air-permeable Fuel mist 15 is transformed.
- the combustion air is in the form of two initially separate air flows L1 and L2 through the dual fuel burner 1.
- the first airflow L1 arrives via a primary, central channel 5 through the spray cone area as the core flow to the atomizer edge 4 of the atomizer lip 3.
- the second air flow L2 passes through a secondary, concentric channel 6 over the outer circumference the atomizer lip 3 to the atomizer edge 4, where it is on as a sheath flow hits the first air flow L1 and the liquid fuel.
- the convergent-divergent Outer contour 10 of the secondary channel 6 with a narrowest cross section in the area of the atomizer edge 4 leads to flow conditions there, which promote the homogenization of the fuel-air mixture.
- the swirl generator 8.9 can the currents in the channels 5 and 6th swirling movements in the same or opposite directions, i.e. Components in the circumferential direction be imprinted.
- the two air flows L1 meet and L2 on the atomizer edge 4 result in speed differences in size and direction and circumferential components to shear and centrifugal forces, with their Help an intimate mixing of fuel and air can be achieved.
- An additional channel 7 is provided for the gaseous fuel G, which between channels 5 and 6 of the combustion air separately into the interior the atomizer lip 3 leads. From there, the gaseous fuel is over Flow connections upstream of the atomizer edge 4 in the primary Channel 5, routed into secondary channel 6 or into both channels 5,6, i.e. With Air and possibly also combined with liquid fuel. It takes also the gaseous fuel on the initiated at the atomizer edge 4 Distribution process part.
- the gaseous fuel will be like that liquid fuel directed into the primary, central channel 5.
- the constructive The conditions for this are shown in a half-section above the X axis. It can be seen that there is a coherent, annular opening the inside of the atomizer lip 3 forms the mouth of the channel 7. as well a variety of holes could form this mouth.
- the gas leak takes place where the fuel film 14 is in liquid operation Moved towards atomizer edge 4. Because of the selected mode of operation (Alternatively) there is no liquid fuel / gas interaction, this is practical irrelevant.
- liquid fuel film 14 on the atomizer lip surface also has an important cooling function. Therefore the gas may be appropriate at several, locally narrowly limited To pass through the fuel film 14, so that between these points sufficiently large, undisturbed film zones remain.
