Definitions
- DC fixed-bed gasifier for producing a product gas from pourable biomass particles
- the invention relates to a DC fixed bed gasifier for producing a product gas from pourable biomass particles according to claim 1, a method for operating such a DC fixed bed gasifier according to claim 14, a method for starting such a DC fixed bed gasifier according to claim 18 and a method for shutting down such DC fixed bed gasifier according to claim 19.
- Fixed bed gasifier for producing a combustible product gas from biomass pellets, in particular from wood chips or wood pellets, are characterized by a comparatively simple structure.
- the flow direction of the combustion air and the product gas on the one hand and the feed direction of the biomass particles are opposite and, in the case of the direct current gasifier, the feed direction of the biomass particles coincides with the flow direction of combustion air and product gas.
- a distinction is made between different reaction zones, namely drying, pyrolysis, oxidation and reduction zones, in which different thermochemical reactions take place.
- the position of the oxidation zone is determined by the position of the air supply by means of nozzles.
- the air supply by means of nozzles has the disadvantage that in the area of the oxidation zone no homogeneous air distribution takes place and temperature differences of up to 400 degrees can occur locally. This can lead to deposits of incineration residues (slag) at undesirable locations in the gasifier compartment, this impairs the movement of the biomass particles and causes an inhomogeneous gas flow which leads to increased tar values in the product gas.
- the fixed bed gasifier Due to the air supply from above and the withdrawal of the product gas below the grate, the fixed bed gasifier only flows through from top to bottom.
- the drying zone and the pyrolysis zone forms in the carburetor component, which protrudes into the carburetor tank, the oxidation zone is formed below the open end of the carburetor component followed by the reduction zone above the grate.
- the local binding of the oxidation zone is effected by the gas flow from top to bottom and by means of a cross-sectional jump between carburetor component and carburetor at the open end of the carburetor component, resulting in different flow velocities.
- Another advantage of the cross-sectional widening is that the pyrolysis gases are limited by no pipe wall when flowing through the oxidation zone. On pipe walls, there are no uniform flow conditions and therefore no evenly high temperatures. If pyrolysis gas flows through the oxidation zone at the edge of a pipe wall, as is the case in the prior art, the long-chain hydrocarbons are not completely broken up. Due to the absence of the pipe wall, additional long-chain hydrocarbon compounds are broken up, which leads to an improvement in the engine capability of the product gas.
- the advantageous embodiment of the invention according to claim 2 to 4 simplifies the construction of the DC Fettbettvergasers and allows a uniform air and product gas flow with a temperature-homogeneous oxidation zone a Most of the long-chain hydrocarbon compounds breaks up and thus produces a high quality product gas.
- the distance h of the open end of the carburetor component corresponds approximately to the diameter d of the carburetor component. This optimum was found empirically. If the distance h is smaller than this optimum, the reduction zone decreases, which has a negative effect on the product gas quality. If the distance h is greater than this optimum, the reduction zone increases, which likewise has an unfavorable effect on the product gas quality.
- the inner diameter d of the tubular carburetor component must be so large that a bed of biomass particles can form in the carburetor component.
- the empirically found ratio interval of inner diameter D of the carburetor tank to inner diameter d of the carburetor component given in claim 7 results in a functional DC fixed-bed carburettor.
- the biomass particle conveyor as a lock for supplying the biomass particles in used the tubular carburetor component.
- This embodiment can also be used independently of the present invention in other fixed bed gasifiers.
- the product or wood gas produced in the DC fixed bed gasifier is preferably used in a CHP with an internal combustion engine or a fuel cell to provide electrical and thermal energy.
- the product gas generated in the DC fixed-bed gasifier is cooled and cleaned in a downstream gas treatment facility.
- this cooled and purified product gas is mixed with cold combustion air compared to the product gas from the gas processing device, whereby further cooling takes place. This further cooling can lead to unwanted precipitation of solids or liquids and in particular of tar.
- the product gas is cooled to temperatures, so that it is z. b. can be used as fuel in a CHP.
- the advantageous embodiment of the invention according to claim 13 ensures that the Biomasszwechen sectionung in the carburetor component is high enough to distribute the amount of air flowing through the Biomasszwechen section sufficiently and evenly before the first reaction zone over the entire cross section. Due to the continuous supply of combustion air via the biomass particle bed and the continuous removal of the product gas, the various reaction zones of the DC fixed-bed gasifier remain stationary and defined conditions are formed. The use of biomass pellets as biomass particles is advantageous. Claim 16.
- the method of starting up a DC fixed bed gasifier according to claim 18 relates to a simple and preferred way of starting the biomass particle filled DC fixed bed gasifier.
- the ignition of the Biomasseteilchen takes place in an advantageous manner by the blowing of hot air in the area under the open end of the tubular Vergaserbauteils.
- the temperature of the hot air is chosen so that the biomass particles are safely ignited.
- the level of biomass particle discharge in the tubular gasifier component decreases and as few as possible unused biomass particles remain. If a large proportion of unused biomass particles remained in the tubular carburetor component after the end of the air supply, this outgassing and the moist gas would lead to swelling of the overlying biomass particles. This swelling can then lead to a clogging of the tubular carburetor component when restarting.
- Figure 1 is a schematic sectional view of an exemplary embodiment of the invention with the essential components.
- Fig. 2 is a schematic representation of the combination of Gleichstrom- fixed bed gasifier of Figure 1 with gas treatment and CHP.
- Fig. 3 shows the biomass particle bed in the gasifier and the various reaction zones.
- Fig. 1 shows a schematic representation of an exemplary embodiment of the invention.
- the DC fixed-bed gasifier according to the present invention comprises a tubular carburettor tank 2 whose ends are closed with an upper lid 4 and a lower lid 5.
- a tubular carburetor component 6 with an open end 8 and a closed end 9 protrudes into the carburetor tank 2 with the open end 8.
- the closed end 9 of the carburetor component 6 projects through the upper lid 4 out of the carburetor tank 2.
- the open end 8 of the carburetor 6 comes to lie approximately in the middle of the carburetor tank 2.
- a rotatable grate 10 is arranged, which can be moved periodically by a motor drive 12 which passes through the lower lid 5.
- a motor drive 12 which passes through the lower lid 5.
- an air supply 16 for supplying combustion air L in the carburetor tank 2 and a level sensor 18, with which determine the level of biomass particles in the tubular Vergaserbauteil 6 and monitor.
- an ignition device 20 and a closed inspection shaft 22 are provided, which penetrate the outer wall of the carburetor tank 2.
- the ignition device 20 is used to generate hot air in a temperature range between 300 ° C and 600 ° C to ignite when starting the DC fixed bed gasifier, the biomass particles in the area below the open end 8 of the carburetor, ie in the region of the oxidation zone.
- the ignition device 20 includes an air nozzle 21 for hot air, which passes through the carburetor tank 2. Through the air nozzle 21 made of ceramic, the parts of the ignition device 20, which are arranged within the carburetor tank 2 are thermally decoupled from the parts outside of the carburetor tank 2. About the inspection shaft 22 can be made at standstill of the reactor, maintenance, cleaning in the reactor tank interior.
- product gas PG 24 is withdrawn from the carburetor tank 2 via a product gas take-off.
- the ash falling through the grate 10 is discharged from the fixed-bed gasifier through the product gas stream PG via the product gas outlet 24.
- Both the tubular carburetor tank 2 and the tubular carburetor component 6 have an annular cross-section and are arranged concentrically to each other.
- the tubular carburetor component 6 has an inner diameter d which is smaller than the inner diameter D of the tubular carburetor tank 2.
- the feed for biomass particles 14 is connected via a first lock valve 28 to a biomass particle conveyor 30 in the form of a screw conveyor.
- the screw conveyor 30 is connected in a gas-tight manner to a biomass particle reservoir 32, which is closed to the outside via a second lock valve 34 in a gastight manner with respect to the surroundings.
- these two components act as sluice for feeding biomass particles into the fixed-bed gasifier between the two lock valves 28, 34.
- FIG. 2 illustrates the combination of the fixed-bed gasifier according to FIG. 1 with a downstream gas conditioning device and a CHP.
- the product gas PG leaving the product gas outlet 24 is supplied to a gas treatment device 36.
- the product gas is cooled in a heat exchanger and solid and liquid impurities are separated as far as possible.
- the cooled and treated product gas from the product gas treatment device 36 is fed to a gas mixing section 40 of a gas engine 42 via a product gas line 38.
- the gas mixing section 40 also includes a supply of combustion air 44.
- the mixture of relatively cold outside air and comparatively hot product gas from the product gas processing device 36 in a mixed gas line 46 the resulting gas mixture is further cooled, so that further liquid impurities can fail.
- These liquid impurities settle in a condensate separator 48 at the end of the mixed gas line 46 immediately before feeding the gas mixture to the gas engine 42 and can be discharged. This increases the quality of the mixed gas and prevents harmful impurities in the gas engine.
- FIG. 3 shows the DC fixed-bed gasifier in the stationary operating state with the biomass particle bed 50 in the carburettor tank 2 and in the carburetor component 6 and the position of the various reaction zones.
- the oxidation zone OZ is formed Immediately below the open end 8 of the carburetor component 6, the oxidation zone OZ is formed. Under the oxidation zone OZ is the reduction zone RZ, which extends to the grate 10.
- the pyrolysis zone PZ extends over the oxidation zone OZ and the completion zone forms the drying zone TZ.
- the carburetor tank 2 is initially filled via the feed 14 to a desired level SP with biomass particles, so that the biomass bed 50 results.
- the ignition device 20 By injecting hot air by means of the ignition device 20, the biomass particles are ignited immediately below the open end 8 of the carburetor component 6, so that the oxidation zone OZ can form.
- the ignition device 20 is switched off and already now combustion air L is supplied via the air supply 16.
- the remaining reaction zones gradually form.
- the product gas stream from the product gas vent 24 is supplied to the gas treatment device 36. In the gas treatment device 36, the product gas quality is monitored.
- the product gas stream from the product gas vent 24 is flared due to its poor quality in an exhaust flare (not shown).
- the product gas in the gas processor 36 is cooled and as far as possible freed of solid and liquid contaminants.
- the target level SP of the biomass particles in the gasifier component is monitored by the level sensor 18 and, if necessary, monitored via the biomass particle feeders. means 30, via the first gate valve 28 and the feed 14 biomass particles refilled.
- the supply of biomass particles is first stopped so that the level of the biomass particles in the gasifier component 6 drops below the desired level SP. If a large proportion of unused biomass particles remained in the tubular carburetor component after the end of the air supply, this outgassing and the moist gas would lead to swelling of the overlying biomass particles. This swelling can then lead to a clogging of the tubular carburetor component when restarting.
- a minimum biomass particle level MP is reached, the air supply and the gas production are stopped. This minimum level MP corresponds approximately to the upper limit of the pyrolysis zone PZ in the stationary operating state. In this way, as little unconsumed biomass particles remain in the carburettor tank 2 and in the carburetor component 6.
- Particularly suitable for the fixed bed gasifier according to the present invention are wood pellets or biomass pellets.
- Kaolin is added to the biomass pellets during production, so that the finished pellets contain a kaolin content of 1 mass% to 5 mass% and preferably of 1.5 mass% to 3 mass%.
- the addition of kaolin increases the melting point of the ashes obtained in the biomass gasification, so that clogging of the grate 0 or undesired attachment of the ash to other components of the fixed bed gasifier is less likely or avoided.
