Definitions
- the invention relates to a swirl setting device for air and fuel gases in burners for the combustion of pulverulent or fine-grained, liquid and / or gaseous fuels, in particular for rotary kilns with at least one primary air duct and at least one combustion nozzle.
- air channels can either be arranged coaxially on the outside or between the fuel channels.
- the nozzle cross-sections are adjustable from the cold end of the burner.
- the swirl air duct is provided with a helical vortex at the end of the nozzle.
- Axial air nozzles are usually designed to be divergent and have an annular cross section or are divided into several cross-sectional segments, which can be round or rectangular. Designs are also known which have a centrally arranged air duct, but which have hardly any influence on the shape of the flame.
- a burner is known from DD-PS 132 022, in which the air guidance system is rigidly installed. Depending on the given arrangement, which cannot be adjusted during operation, angles of attack of up to 80 ° can be specified here, but these cannot be changed during operation.
- EP-OS 132 831 shows an injector burner in which flexible pipes are used.
- the corrugated surface of the flexible tubes which are designed as a corrugated hose, is used in order to achieve better mixing.
- Such a hose can be installed in a bent position, which can increase the turbulence. A change in the angle of attack in operation is not provided for in this training and is also not possible.
- the swirl adjusting device essentially consists in the primary air duct containing a plurality of flexible pipes, the ends of which facing away from the Brehner nozzle can be rotated concentrically with respect to the axis of the burner and / or are displaceable in the axial direction of the burner, and their ends facing the burner nozzle in the axial direction of the burner are slidably and / or pivotally mounted.
- the ends facing the burner nozzle can only be pivoted if the ends facing away from the burner nozzle are mounted so as to be displaceable in the axial direction of the burner, with the ends of the flexible tubes facing away from the burner nozzle also being displaced in this case due to the flexibility of the tubes If the ends of the pipes facing the burner nozzle are only pivotably mounted, the exit angle changes, since the rise in the helical lines in turn changes.
- the design can be such that the storage of the free ends of the flexible tubes is formed by slots or elongated holes running in the longitudinal direction thereof, which cooperate with bolts which are essentially radial to the burner axis, as a result of which the desired kinematics the adjustment of the flexible pipes is ensured with a simple common drive.
- the drive can act on a common part which is designed as a support, the design advantageously being such that the ends of the flexible tubes facing away from the burner nozzle are fixed in an annular disk-shaped support which is provided with a drive for Rotation of the carrier and / or for moving the carrier in the direction of the burner axis is connected.
- the drive can be formed by a simple hydraulic drive if only an axial displacement of the annular disk-shaped carrier is required in order to influence the exit angle from the flexible tubes.
- a rotation of the carrier can be effected with such a displacement drive if the carrier itself is rotatably guided in helical grooves, and thus at the same time the carrier is also rotated with an axial displacement of the carrier.
- the free ends of the flexible tubes must be displaceable in the axial direction, for which, as mentioned above, the slots or elongated holes running in the longitudinal direction can be provided together with radial bolts.
- a rotary drive can, for example, contain a toothed sleeve, the teeth of which mesh with a drive pinion.
- the design is such that the flexible pipes open into an area of the primary air duct with an annular cross section, and that the primary air duct tapers into an annular nozzle following the mouth of the flexible pipes.
- the desired rotation of the air flow, and consequently the flame shape can be set precisely and in a user-friendly manner by means of an adjustment device with an indicator scale attached to the cold end of the burner.
- FIG. 1 shows a view of the swirl adjusting device, partly in section
- FIG. 2 shows an axial section through the configuration according to FIG. 1 with the flexible tubes being oriented essentially axially.
- the flexible swirl setting device is located in an annular primary air duct 1 about 0.5 m from a burner outlet nozzle 2.
- about 12 to 36 flexible tubes 3 with a length of about 350 mm are arranged in a planetary manner on the circumference in the annular duct 1.
- the front ends 4 of these flexible tubes are rotatably and axially slidably attached.
- the rear part of the hoses or tubes 3 is contained in a ring 5 which is rotatably mounted about the axis of the burner.
- the ring 5 is rotated via the rotatable sleeve 6, which has external teeth, a pinion 7 of a drive shaft (not shown) meshing with this external toothing.
- the ends 4 of the flexible tubes facing the burner nozzle 2 open into a rotation chamber 8 which is arranged directly in front of the outlet nozzle 2.
- the flexible tubes 3 nestle helically against the inner tube 11, the free ends 4 of the flexible tubes being deflected relative to the burner axis 9 depending on the angle of rotation of the ring. Since the rotatable ring 5 is mounted almost tightly between the inner tube 11 and the outer tube 10, the air flows through the flexible tubes 3 into the rotation chamber 8. In this rotation chamber 8 the rotation takes place depending on the deflection angle of the ends 4 of the flexible tubes.
- the ring 5 is rotated from the cold end of the burner.
- the outer tube of the burner is designated by 10.
- the rotatable sleeve 6 is slidably mounted on the inner tube 11.
- the free ends 4 of the flexible tubes 3 have a slot 12 running in the axial direction, in which a bolt 13 engages.
- a length compensation in the region of the front ends 4 can take place when the annular carrier 5 is rotated and the slope of the helix of the flexible tubes 3 changes, and when the outflow angle to the axis increases, a corresponding shortening and thus a corresponding displacement of the free ends 4 takes place in the guide formed by the slot 12 and the bolt 13.
