Definitions
- the invention relates to a device for burning, in particular inert coal dust, according to the preamble of the main claim.
- EP-OS-0 111 874 discloses a device for burning, in particular inert coal dust, which has the features of the generic term of
- the object of the invention is to adapt the combustion process in the device to different operating conditions and types of coal, i. H. to take into account the condition of the device when starting up and during operation, on the one hand, and the type of coal dust, in particular the proportion of volatile constituents, on the other hand, in such a way that ignition can take place without problems, the flame is stabilized and certain temperatures are maintained or at certain points in the Device neither be exceeded nor undershot.
- This is intended to achieve a high degree of efficiency of the device, e.g. e.g. B. high burnout and thus a low proportion of the unburned combustible material should be achieved in the ash.
- This task should be achieved with structurally simple and easy to use and maintain means that can also be attached to existing devices of the generic type.
- the invention provides the features of the characterizing part of the main claim.
- the features of the subclaims serve to improve and further develop the features of the main claim.
- the coal dust is brought into such a state that it largely corresponds optimally to the respective state of the device and the type of coal, i. H. um u. a. to achieve immediate, trouble-free ignition, to adapt the combustion to the respective type of coal, to keep the temperature environmentally friendly and to achieve a favorable burnout.
- DE-A-1 501 981 discloses a combination burner for the simultaneous or optional combustion of gas, preferably top gas and coal dust, in which the guide tube for the secondary air is arranged coaxially with the burner tube.
- a burner tube for the supply of coal dust with primary air and a gas supply centrally surrounding the front end of the burner tube are used.
- An in the front burner tube end and out and retractable is acting as a closure member of the burner tube impeller with the help of a push and pull rod such that the impeller is wholly or partially in or outside the tube and thus either the coal dust or the gas or a mixture of both the way is released into the combustion chamber.
- a regulation and control of the amount of only the coal dust as the only medium in the device is not possible with this device and therefore gave the person skilled in the art no hint to achieve the object of the present invention.
- the device according to the invention has a burner muffle 1 which is conical and widens from its front end 2 to its rear end 3.
- the front end 2 has a swirl device 4, in which the combustion air supplied via the line 5 is introduced tangentially into the muffle 1 and is set into a helical swirl flow 6 in the muffle.
- the other devices, such as the ignition device, etc., are not shown in detail and are of a known type.
- a tubular feed lance 7 protrudes through the burner muffle 1 in its longitudinal axis. H. near the rear end of the muffle 3 carries a cap 8 which causes the direction of the conveying air for the coal dust and the coal dust itself in the lance (arrow 7a) to be reversed and this in the direction of the arrows 9, producing a flow part 10b emerge from the cap 8.
- the combustion air passes from the muffle 1 into a combustion and acceleration chamber 11, the helical swirl movement of the combustion air being maintained as an internal swirl flow 12 along the solid lines.
- the flame 13 forms, which, for. B. protrudes into the boiler room 14 of the downstream boiler 15.
- the combustion and acceleration chamber 11 has a conical shape, the wall 16 of the chamber 11 tapering from its front to its rear end 17.
- the cross section of the core 11 at the transition between the muffle 1 and the combustion or acceleration chamber is kept larger than the cross section at the rear end 3 of the burner muffle 1. This forms an annular channel 18 and a jacket-like extension 19 of the acceleration chamber.
- air or gas nozzles inserted tangentially into the wall 16 are arranged in the successive transverse planes a to e, which can have the same or approximately the same distance from one another, and bear the reference numbers 20 to 27 in FIG. 1 and which either have different angles of attack to the transverse planes or are adjustable relative to these transverse planes.
- Air or gas jets emerge from the nozzles 20 to 29 in the direction of rotation or rotation of the inner swirl flow 12 of the combustion air loaded with coal dust and produce a swirl flow from the rear end 17 of the combustion or acceleration chamber which runs in the opposite direction in the longitudinal direction of the combustion and acceleration chamber 11 11 to the rear end 3 of the muffle 1.
- This external swirl flow which is created or promoted by the air or gas jets from the nozzles 20 to 29, is symbolized by the dash-dotted line 30.
- the wall 40 of the swirl device 4 has an axially located guide bush 41 which partly projects into the muffle and partly from the muffle 1 and in which the feed lance 7 can be displaced in the direction of the double arrow P in such a way that the cap-like part 8 of the lance 7 1 as well as the withdrawn position 8a is able to assume both.
- the path of the conveying air and the coal dust particles in the muffle 1 is either lengthened or shortened.
- the position of the lance and its cap 8 can be determined by means of sensors 42, 43 in the wall 16 of the combustion and acceleration chamber and by a sensor 44 in the wall of the muffle, which if necessary via a computer R with the control device 45 for driving the Lance 7 in the direction of the double arrow P takes place.
- the path of the dust particles can be changed in the direction of the arrows 10 in the sense of the task at hand if a control valve 46 is installed in the feed line 5, which can also be controlled by the computer R.
- the swirl device is supplied with an advantageous amount of combustion air, which is preferably, for. B. is preheated as cooling air of the wall of the combustion and acceleration chamber 11.
- the control valve 46 for controlling the combustion air in the swirl device 4 is combined with a control slide 53, which is designed like a can and at the inner end of the wing 54 the swirl device 4 is adjustable in the direction of the arrow S.
- the quantity and speed of the combustion air entering the muffle 1 can be advantageously controlled, in particular for the ignition process and the stabilization of the flame, for a high efficiency of the device.
- the housing of the swirl device 4 has an extension 4a, into and out of which the control slide can be moved.
- a further possibility of controlling the combustion air in the muffle 1 and thus the path of the air and the coal dust particles along the arrows 10a and 10b is to adjust the wings 54 of the swirl device 4 in their angular position.
- the muffle 1, the swirl device 4 and the feed lance 7 with its guide bush 41 as well as the computer R and the control valve 46 are designed in the same way as in the embodiment according to FIG. 1.
- the combustion and acceleration chamber 11 is cylindrical and has the nozzles 20 to 29 at regular intervals.
- the rear end of the combustion and acceleration chamber 11 has a rear wall 36, to which an ash outlet 35 can be assigned.
- Another ash outlet 37 can be assigned to the wall 31.
- the combustion and acceleration chamber 11 can have a further combustion and acceleration chamber 50 be assigned, which adjoins the wall 36, which carries a central sleeve or sleeve 51 with a further swirl device 52.
- the hot flue gases pass into the boiler 15 from this further combustion and acceleration chamber.
- the parts of the muffle 1 are designed in the same way as in the embodiment according to FIG. 1.
