Definitions
- the present invention relates to a burner for solid fuels according to the preamble of claim 1.
- Firings for particulate solid fuels are common designed to be gas-tight within one with the exception of a flue gas outlet running cup space a cup-shaped burner is arranged. In these Burner pot are fed substantially continuously, the fuel pieces and burn in it. Wood pellets are pressed sawdust od. Like., Which are present in a piece size of a few millimeters. usual Pellets have a diameter of 6 mm or 9 mm and a length of about 25 mm.
- the burner pot is relatively due to the continuous supply of fuel small. Therefore, even comparatively small amounts of ash lead to a Impairment of the combustion process and deterioration of the Ignition behavior.
- the arrangement of a grate at the bottom of the burner pot indeed, would allow for falling through of ashes, it is However, in such a case, no controlled operation of the burner possible because an uncontrolled air movement through the burner pot occur would, which makes an optimal combustion process impossible.
- US 4,366,802 A shows a burner for sawdust and pellets, with a Storage hopper from which the fuel falls down. In the firing is arranged a grid on which the combustion takes place and through which the Ash can fall through. Since there is no burner pot, there is no comparability given with the present invention.
- JP 56-094126 A discloses a device for burning rice husks described. It is merely a rust revealed at the bottom of the Burner tube is arranged, through which rust ash can fall through.
- GB 2 056 638 A shows only a firing system with a movable Rust. It is a burner with a pantry and a Rüttelrost described, through which the resulting ash can be removed.
- burner does not have a burner pot in the sense of the invention, that is, a component which is disposed within the actual combustion chamber and always only a small amount of fuel intended directly for combustion receives. It is further evident that the conclusion by the rust by no means is airtight, since the individual grate elements have openings, so that a controlled combustion management is not achievable.
- the object of the present invention is to provide a burner of the type described above To develop the type so that a stable operation is possible and that the resulting Ash can be collected and disposed of in a controlled manner.
- Another particularly preferred embodiment of the invention provides that in the plate in the central region a recess is formed through the a mandrel for supplying primary air protrudes into the burner pot. It is cheap thereby, when the mandrel is designed to increase the distribution of fuel, wherein preferably its height at least half the height of the burner pot accounts. Due to the centrally arranged mandrel is a particularly uniform Distribution of the primary air and the pellets achieved, resulting in a more uniform Burning is guaranteed.
- the present invention relates to a method for burning solid Fuels according to claim 8.
- FIG. 1 shows a burner according to the invention in a longitudinal section.
- the burner consists of a burner pot 1, which is a substantially cylindrical wall 2 has.
- the wall 2 has an outwardly directed top Extension 2a.
- the pot 1 is open at the top to the insertion of To allow wood pellets by a fuel supply, not shown.
- At the bottom of the burner pot 1 is closed by a plate 3, having the openings 4 and 5.
- FIG. 2 the arrangement of the openings 4 and 5 of the plate 3 can be seen.
- the openings 4 are designed as slots and at equal angular intervals arranged symmetrically to the center M of the plate. Radial outside everyone Opening 4 is provided in each case a circular opening 5. Furthermore owns the Plate 3 a central recess. 6
- a sheath 7 is provided which together forms an annular space 8 with the wall 2. From this annulus 8 can secondary air via secondary air openings 9 blown into the interior of the burner pot 1 become.
- the secondary air openings 9 are in the upper region of the side wall 2 arranged in two rows one above the other.
- a secondary air duct 10 opens into the annular space 8, to introduce the secondary air in the annular space 8.
- a frusto-conical inner wall 11 is provided, through which the burner pot 1 is tapered downwards.
- a mandrel 12 from below centrally into the burner pot 1, whose height h is about 60% of the total height H of the burner pot. 1 accounts.
- the fuel supply is adjusted so that the fuel pellets hit the mandrel 12 and so evenly inside the burner pot 1 distributed.
- the interior 13 of the mandrel 12 is via a primary air line 14 supplied with combustion air. This primary air is via openings 15 in the mandrel 12 evenly introduced into the lower region of the burner pot 1.
- a Zündlufttechnisch 16th Centrally within the primary air line 14 is a Zündlufttechnisch 16th arranged, which the heated by a hot air source, not shown ignition air for starting the burner via the openings 15 in the interior of the burner pot 1 contributes.
- a further plate 19 is arranged, with openings 20, 21st is provided in the form and arrangement substantially the openings. 4 and 5 correspond to the plate 3.
- the further plate 19 is opposite the fixed one Plate 3 rotatable, in such a way that in one position the other Plate 19, the openings 20 with the openings 4 of the plate 3 in accordance are. In this way, ashes, located in the lower part of the burner pot 1 has accumulated, fall out down. In the same way are in this Position the openings 21 of the plate 19 with the openings 5 of the plate 3 in Coverage. Therefore, ashes through the air supply openings 18 in the Space 22 outside or below the frusto-conical inner wall 11 penetrated is to be removed reliably.
- a control device also not shown controls this actuator so that after expiration of a time interval in the suspected can be that has collected a considerable amount of ash, a Cleaning process is performed by the openings 20 and 21 and 4 or 5 are brought into line.
- a very suitable parameter to control the ash removal is since the last cleaning process performed number of revolutions of the screw to the fuel supply.
- FIG. 3 essentially corresponds to that of FIG the consequence, therefore, only the differences are discussed.
- the further plate is in this embodiment variant designed as a double plate 29, consisting of two similar Washers 29a and 29b and an annular connector 29c consists. Since this connector 29c covers the slot 24 is a separate one Cover plate not required.
- the primary air supplied through the primary air duct 14 enters the gap 29d between the discs 29a and 29b of the double plate 29 and flows through the openings 20a of the upper disc 29a in the burner pot. 1 on.
- the openings 20b of the lower disc 29b are during normal operation closed by the plate 3, so that no air loss occurs. Only if the double plate 29 is rotated so that the openings 20 a and 20 b and 4 so that the ash can fall through, the air supply is not regulated.
- the ignition air is blown through openings 15 in the mandrel 12 to a good ignition to ensure.
- the mandrel 12 is in this embodiment of a ceramic material and fully formed in the upper part. Otherwise corresponds this embodiment substantially the same as described above.
- the burner according to the invention is in a conventional manner in a combustion chamber arranged, which is airtight except for the flue gas outlet.
- a suction fan on End of the heater and heat exchanger located in front of the exhaust pipe.
- ash tray which can hold a larger amount of ash. This ash drawer must be emptied by the user at longer intervals.
- a particular advantage of the invention is that by the reliable Removal of the ashes and the special arrangement of Zündgasrohres a easy and safe ignition of the burner achieved during commissioning can be.
- a uniform supply of the ignition air and due to the low heat capacity of the tube 16 in the interior of the primary air supply 14 and by the central supply of the ignition air through the openings 15 in Dorn 12 can be a particularly fast ignition with a small amount of ignition air be achieved.
