Definitions

  • the invention relates to a device and a method for the thermal conversion of pellets or wood chips.
  • Heating systems for burning organic substances such as pellets are well known in the art. That's how it describes EP 1 384 031 B1 a burner for burning solids, in particular pellets, which is installed in the wall opening of a boiler, wherein the wall opening is constructed such that it at least partially surrounds the combustion chamber. The main focus is on the connection of burner and boiler.
  • the known from the prior art heaters is essentially no device downstream, which serves the flue gas cleaning and the exhaust gas condensation, so that the operation of such firing systems is associated with pollutant emissions, which can exceed the legal limits usually prescribed.
  • particles with particle diameters of 50 nm to 200 nm may be emitted, the removal of which from the exhaust gas is known by filtration, scrubbing or electrostatic precipitators.
  • Such a plant for the purification of flue gas is for example in the DD 289 474 A5 disclosed.
  • reagents must be added to the flue gas stream, which form further compounds after reaction with the pollutants, which are deposited in a filter.
  • the acted upon by the pollutant compound filter must therefore be disposed of consuming or further cleaned.
  • Such a filter cleaning can be done mechanically, for example via pressure, combined with further equipment expense.
  • a cleaning of the filter by burning leads to high ash production, which leads to further disposal problems.
  • exhaust gas scrubbers are known from the prior art.
  • DE 199 06 061 A1 describes, for example, a device for low-emission combustion of non-fossil fuels, the resulting flue gas is supplied to a gas scrubber after cooling.
  • the apparatus design of a scrubber is complex and leads to the formation of wastewater, so that the use of a gas scrubber for flue gas cleaning in non-industrial burner systems is not practical.
  • the object of the invention is to provide a device and method improved with regard to the thermal conversion of pellets and wood chips with regard to calorific value utilization and particulate combustion exhaust gas emission.
  • An embodiment of the present invention relates to a device for the thermal conversion of pellets and wood chips, which has a conveyor, which leads the pellets and wood chips after previous charring in a charring zone in a Vergaserzone. There, the conversion to generator gas, which is finally burned by means of a burner.
  • This conversion is advantageously carried out with high efficiency, since the previous charring, which takes place in the heatable conveyor, optimally prepares the material to be combusted for conversion to generator gas after the Boudouard equilibrium, which ultimately causes a combustion of gas with low particulate pollutant emissions.
  • Another embodiment of the present invention has gasification chamber for performing the gasification, which has an air supply device and an outlet for the generator gas produced in the chamber, which with the arrangement of a feed opening leads the charred fuel in a countercurrent flow of gas and air, so that advantageously a uniform burning and gasification takes place in the combustion chamber.
  • the heated conveyor can be driven in DC, so that both flow principles combined effect an optimized implementation of the fuels. Due to the advantageously optimized thermal conversion less particles are emitted from the device; thus the pollutant emissions are reduced.
  • Another embodiment relates to the apparatus for thermal conversion of pellets and wood chips, comprising a supply device for the same, which communicates with the conveyor for conveying the fuels into the gasification chamber.
  • the non-return valve which is advantageously arranged between the conveying device and the feeding device, prevents the rejection of charring gases already produced in the conveying device in the direction of the feeding device.
  • Further embodiments relate to a device for heat transfer, which is arranged near the gasification chamber and / or the conveyor such that it advantageously absorbs the waste heat of the resulting combustion exhaust gases and advantageously returns them there in the process where energy is needed for heating. This advantageously improves the energy balance of the combustion process.
  • the invention provides a method for the thermal conversion of pellets and wood chips, the method being characterized in that it is carried out with the device of the preceding embodiments.
  • the devices according to the invention for the thermal conversion of solid organic fuels include a conveyor for conveying the pellets and wood chips, operated in countercurrent carburetor zone, operated in the co-current principle, the carburetor zone upstream charring zone and a generator gas burner.
  • the conveyor has a heater, so that the fuel can be preheated up to the charring.
  • the charring zone lies within the conveyor.
  • Conveyor is meant a single or multi-part device, with active or passive conveying are included.
  • the conveyor may be a screw conveyor, or a chute, a downpipe or combinations of both.
  • a separate heating of the corresponding conveyor may be present in the wall, it is also conceivable that one or all of the funding, which form the conveyor, are heated from the outside.
  • the conveyor from the outside can be in the absorption of heat energy through a heat exchange device, which rests on the conveyor.
  • the gasification takes place in a gasification chamber, which is equipped with at least one feed device. This is to be understood as an opening which is suitable for allowing the supply of the combustible materials into the gasification chamber.
  • the gasification chamber has an outlet for the generator gas produced in the gasification and charring process.
  • a burner or "generator gas burner” is arranged on the generator gas outlet of the gasification chamber.
  • Fig. 1 shows an example of a device according to the invention for the thermal conversion of organic solids, with horizontally arranged screw conveyor and vertically arranged burner. Therein is a funnel-shaped feeder for the fuels arranged above a screw conveyor 2 that the fuels fall down and get into the screw conveyor 2. The screw conveyor 2 is heated, so that during transport through the screw conveyor 2 is already a charring of transported fuels.
  • the fuel feeder and the screw conveyor 2 may be arranged in a different way to each other, a pipe connection between the two, for example, allows a spatially distant arrangement.
  • the screw conveyor 2 is coupled to the gasification chamber 3 such that the gasification chamber 3 is acted upon directly by its feed opening 8 with the charred fuels coming from the screw conveyor 2.
  • the resulting in the charring gases enter the burner 4, since they are moved by the screw conveyor 2 in cocurrent with the transported combustion materials. So that the gases produced during the charring do not reach the feeding device, a non-return valve designed as a rotary valve 6 is arranged between the conveying screw 2 and the feeding device.
  • a (not shown) heated pipe can be arranged as a passive conveyor. It is then sufficient to use a shorter screw conveyor 2, which merely sets the material in motion and preheats.
  • the charring can then also be carried out in the heating tube, so that the charring zone as a whole is located in the conveying device 2 and tube designed conveyor.
  • a plurality of air supply openings in the wall of one of the conveying means or the conveying means makes this possible.
  • the firing material After the firing material has been charred and has passed through the feed opening 8 into the gasification chamber 3, it is flowed through the blower 5 with air.
  • the charcoal reacts first in the lower layers with the supplied atmospheric oxygen to carbon dioxide.
  • the oxidation process of the coal is subject to the Boudouard equilibrium, so that further carbon monoxide is formed.
  • the gases rise in the gasifier chamber 3 upwards, so that an upper zone is formed in the gasification chamber 3, in which by raising the temperature to about 1100 ° C, the Boudouard equilibrium is shifted so that it is on the side of the carbon monoxide. Further, the high temperature causes the tar contained in the carbonization gases passing through to be pyrolyzed.
  • the resulting so-called generator gas rich in carbon monoxide, is then converted by combustion by means of the burner 4 to carbon dioxide when it exits through the generator gas outlet 9 from the gasification chamber 3.
  • the flow conditions are determined in the gasification chamber 3 by the countercurrent principle, whereby a uniform Abreagieren takes place.
  • a further connected to a further blower 5 air supply line is further connected, so that the correspondingly necessary atmospheric oxygen is available for the combustion process.
  • Generator gas outlet 9 and burner 4 are surrounded by a device for heat transfer, a heat exchanger 11.
  • the combustion exhaust gas moves meandering through the heat exchanger device 11 before passing out through the combustion exhaust gas outlet 7.
  • the ash produced during the process is led out of the device through an ash outlet 10, which is present in the bottom of the gasification chamber 3.
  • the movement of the ash stream is indicated by the arrow b in FIG. 1 displayed.
  • the heat exchanger may be arranged in further, not figuratively shown embodiments so that it extends from the burner to the heatable conveyor. It may extend at the same time or instead only to the gasification chamber, so that the thermal energy of the conveyor or the gasification chamber can be supplied.
  • the auger used as a conveyor is preferably made of a high temperature resistant stainless steel or a ceramic; As a particularly temperature-resistant and robust material Cordierite comes into question.
  • the nozzle of the burner and the Verkohlungshunt are also made of a high temperature resistant material, there are in particular aluminum titanate, silicon carbide and aluminum trioxide or other known ceramic compounds as materials in question.
  • the gasification chamber and the nozzle of the burner can be made in one piece. This is advantageously avoided that it comes between nozzle and carburetor chamber to outlet openings for the generator gas, which would otherwise be disadvantageously removed from the further oxidation.
  • materials for the conveyor or the auger are in particular high temperature resistant stainless steels or ceramics such as cordierite in question.
  • FIG. 1 Another spatial arrangement of the device according to the invention is made Fig.
  • the screw conveyor 2 is arranged vertically and protrudes into the likewise vertically arranged carburetor chamber 3, so that the feed opening 8, from which the charred pellets of the gasification chamber 3 are supplied, is already in the same.
  • the screw conveyor 2 is advantageously heated by the surrounding gasification chamber 3.
  • Fig. 2 a spaced-apart funnel-shaped feed device for the fuels, which are conveyed via a feed tube 12 by gravity to the screw conveyor 2.
  • the rotary valve 6, which serves to prevent combustion gases from hitting back in the direction of the feed device, is arranged here between the feed tube 12 and the screw conveyor.
  • the gasification chamber 3 has a generator gas outlet 9, so that the generated generator gas can be converted to carbon dioxide by means of the horizontally arranged burner 4 before it passes into the heat exchanger 11, leaving it as combustion exhaust gas through the outlet 7, as indicated by the arrows a is.
  • An advantage is one Storage device 13 disposed below the heat exchanger 11, so that the stored energy can be supplied to other processes with heat demand.
  • Fig. 3 shows a further arrangement possibility of the device according to the invention. Conveying screw 2 and combustion chamber 3 are arranged as already in Fig. 2 illustrated, however, the generator gas burner 4 is arranged vertically above the gasification chamber 3, so that the combustion gases flow directly counter to this after leaving the Generatorgasauslasses 7. The adjoining the burner 4 and this surrounding device for heat exchange is also oriented vertically.
  • the arrangement shown is particularly advantageous for narrow spaces that allow a high structure.
  • these are first introduced into the conveyor from where they are conveyed to the gasification chamber 3.
  • the fuels are charred to coal and gas, which is done on the DC principle.
  • the charring takes place at a temperature in the range of 400 ° C to 800 ° C, a particularly suitable charring temperature is between 500 ° C and 600 ° C.
  • the fuel can also be first performed by only brought to preheating temperature conveyor at about 300 ° C to 400 ° C before it is exposed in the lying directly in front of the carburetor conveyor the high charring temperatures.
  • coal and gas are conveyed from the conveyor through the feed opening 8 into the gasification chamber 3, they are flowed through in countercurrent from the air supplied via the fan 5, so that oxidation takes place and generator gas is formed. This rises to the hottest zone of the carburetor chamber 3, which shifts the gasification equilibrium in favor of carbon monoxide.
  • the carbon monoxide is burned to carbon dioxide, in which it is subjected to a combustion process under the oxygen or air supply in the nozzle of the burner 4.
  • the combustion exhaust gases flow downstream through the heat exchanger 11 and are thereby cooled.
  • the method may be carried out in such a way that the heat energy released during the cooling is supplied to the process elsewhere, for example by arranging the heat exchanger 11 so that it surrounds the combustion chamber 3 or the conveying device in such a way that these are heated by the cooling combustion gases. Further, the method may preferably be performed so that the air supplied to the burner 4 at the nozzle through the second air supply device is supplied to the combustion with such a small excess air that the generator gas burns at about 1 with an air ratio of ⁇ .
  • the streaming process in the process which initially follows the DC principle in the charring zone, is ideally complemented by the countercurrent principle in gasification, since the DC principle favors a low tar content and promotes the countercurrent principle, a uniform combustion.
  • the device according to the invention and the process carried out with it serve not only for the thermal conversion of pellets or wood chips. It is also possible to thermally convert other forms of combustible solids or other suitable substances which are not present in pellet form but in another form suitable for charring.
