Definitions
- the invention relates to a device for burning renewable, chunky fuels, especially wood pellets, with a combustion chamber connected to a blower for the combustion air
- Wood pellets are usually made from wood chips that come with mixed with a binder and extruded using a screw extruder be, with appropriate heating a substantial Drying is ensured so that such wood pellets compared to natural grown wood a much higher density with a high Have degree of dryness. This difference in density is natural noticeable in the burning behavior. The burning of wood pellets takes place significantly slower than that of naturally grown wood of the same size. This can lead to incomplete burnout of the ashes, if suitable countermeasures are not taken. In addition, that high temperatures in the ember bed must be expected, which is a Slagging and sintering are supported. These drawbacks will be often reinforced by the binders used for the wood pellets.
- the invention is therefore based on the object of a device for Burn renewable, particulate fuels, especially Wood pellets, the type described in such a way that also at smaller heating capacities ensure good use of the fuel can be feared without slagging or sintering have to.
- the invention solves this problem in that the combustion chamber a blowing nozzle for the combustion air and then a Has flame tube preferably with a baffle plate and that a mill for the piece fuels with a in the pressure or suction line of the Blower discharge outlet is provided.
- Heated flame tube becomes the ignition temperature for the shredded fuels ensured that thus emerging from the flame tube Burn out the combustion air flow.
- the control of the heating output is included sensitive with little effort via the dosage of the flame tube supplied Grist possible. Is a for the resulting flue gas flow Baffle plate provided, so some of the flue gases can be circulated the flame tube to be guided to a corresponding combustion route for the regrind particles.
- a flame tube 5 is arranged in the combustion chamber 1, the a heating device, not shown for reasons of clarity is the ignition temperature required for the combustion of the wood pellets to reach.
- the front exit end of the flame tube 5 is in opposite a baffle plate 6 formed by the combustion chamber 1, the for a deflection of the flue gases and their backflow in Annular gap between the flame tube 5 and the combustion chamber 1 provides.
- a part this flue gas is released from the blowing nozzle 4 via the injector effect Combustion air flow torn back into the flame tube 5, so that a circulatory flow is formed.
- the not circulated Flue gases are emitted from the combustion chamber 1 via a flue gas line 7 deducted the combustion chamber 1.
- the wood pellets to be burned are transferred to a mill 8 Grist inlet 9 abandoned.
- This mill 8 for the wood pellets is with your Regrind outlet 10 connected directly to the pressure line 2 of the blower 3, so that the ground wood pellets with the conveying air flow over the blowing nozzle are conveyed into the flame tube 5, where they ignite and within of the combustion air flow that promotes them. It can hence the advantages of such combustion chambers 1 equipped with flame tubes good for combustion in terms of combustion and exhaust control be exploited by wood pellets, without being particularly concerned in the area of Conveying and storage benefits of high density pellets to have to do without.
- the invention is of course not based on the illustrated embodiment limited.
- other renewable, piece fuels are used, for example wood waste, wood chips, Wood chips, grain and. Like.
- the mill will also fuel the changing crushing conditions have to be adjusted.
