Definitions
- the invention relates to a reactor for the gasification of fuels, in particular of biomass, according to the preamble of claim 1. Furthermore, the invention relates to a process for the gasification of fuels, in particular of biomass according to claim 18.
- Reactors for the gasification of fuels in particular of carbonaceous solid fuels (for example biomass or waste and in particular wood or the like substances), with the purpose to use the fuel gases generated in the reactor for energy production or power generation (in particular by means of internal combustion engines, such as gas engines) are well known.
- the gas produced from the solid fuels is referred to differently as product gas, lean gas, wood gas or syngas, wherein the gasification in the reactor provides the product gas, the main components carbon monoxide, carbon dioxide, hydrogen, methane, water vapor and gasification with air as a gasification agent also contains considerable amounts of nitrogen.
- tars or condensates, ashes and dust are produced as undesirable by-products in varying amounts.
- the gasification process in the reactor itself can be roughly divided into the areas of heating or drying, pyrolytic decomposition, oxidation and reduction. This is explained in more detail below on the basis of biomass:
- the biomass is heated, whereby the water therein is evaporated to a temperature level of about 200 ° C. After the heating or drying phase of the biomass takes place at temperatures between 150 ° C and
- Components of the product gas such as carbon monoxide, hydrogen, and methane, are then formed in a reduction zone adjoining the oxidation zone.
- the products formed in the oxidation and drying carbon dioxide and water with solid carbon to carbon monoxide and hydrogen are reduced.
- tars require the use of scrubbers in order, for example, to be able to supply gases released from such residues to the downstream engines.
- DE 100 37 762 B4 specifically proposes connecting a gas purification unit downstream of a gasification reactor which has catalytically active material which is directly exposed to the gases leaving the gasification unit. Furthermore, a gas cooling unit connected downstream of this gas cleaning unit is provided, which in turn is followed by a filter. Specifically, in this case, the gas cleaning unit should have a thermally insulated, vertically from top to bottom flow-through full-room reactor, which has a supply line through which the gases exiting the gasifier unit can be introduced into the full-room reactor.
- Flow direction of the gases flow channels are arranged within the full-space reactor of the gas cleaning unit, which have honeycomb-shaped flow cross-sections and which are formed by a support frame, on which the catalytically active material is provided. Furthermore, a discharge is provided at the full-space reactor, through which the catalytically split gases emerge from the full-space reactor, while in the floor space of the full-room reactor can accumulate flue dust, which in turn can be discharged through a drain port.
- a discharge is provided at the full-space reactor, through which the catalytically split gases emerge from the full-space reactor, while in the floor space of the full-room reactor can accumulate flue dust, which in turn can be discharged through a drain port.
- Such a structure is obviously expensive and inexpensive.
- a shaft furnace in which a tower-like supply for air or gasification means projects into the bulk layer above a ember bed to there, that is, to blow air into the bulk material layer, so that the supplied air here in addition to the fuel gas produced must flow through the bed.
- the fuel gas is also withdrawn ash ash discharge side, that is, after flowing through the entire bed, by means of a fuel gas line, which is connected to a heat exchanger which heats the bulk material layer.
- This preheating zone is used only for drying and preheating, pyrolysis and reduction does not take place in this area.
- a separate muffle tube is not provided here.
- DE 199 16 931 A1 shows a carburettor with a filling zone forming a drying zone and a pyrolysis zone and tapering conically downwards, which merges into a cylindrical region containing the oxidation and reduction zone.
- the fuel gas produced flows through an annealed thermally separated or isolated annulus up to the drying zone upwards, where it is then withdrawn.
- a heat transfer from the raw gas into the bed takes place only in the region of the drying zone.
- the heat supply into the pyrolysis and reduction zone takes place autothermally within the cylindrical shaft via the oxidation zone. Consequently, here too gasification agent and all gas components formed must flow completely through the bed, so that the fuel gas in the region of the grate can flow into the annulus.
- An apparatus for wood gasification which is identical in principle to DE 199 16 931 A1 is also known from DE 10 2007 002 895 A1.
- An essential difference to DE 199 16 931 A1 is that here the gasification agent is supplied via nozzles from the outside and not from the inside.
- a reactor for the gasification of fuels, in particular of biomass which has a reactor interior. Furthermore, the reactor has at least one fuel metering device for adding fuel to be gasified into the interior of the reactor. In addition, a grate arranged in the interior of the reactor, preferably on the bottom side, is provided on which the fuel metered into the interior of the reactor and to be gasified rests.
- the reactor according to the invention comprises at least one gas outlet for discharging the gas generated in the interior of the reactor from the interior of the reactor
- Grating disposed muffle tube is provided, which preferably extends in the direction of the vertical axis, wherein in the muffle tube of the fuel to be gasified is received Hochachsencardi lower or free, rust-side muffle tube in an indirectly or directly acted upon by air from the at least one air supply and formed as an autothermal gasification zone lower reactor area in which the fuel to be gasified or already resulting from this product gases partially oxidize.
- the muffle tube is received in an upper annular region opening into the lower reactor region in an upper reactor region forming a muffle housing such that the gas emerging from the muffle tube in the region of the lower or free muffle tube, preferably with mixing with gas from the autothermal gasification zone, enters the muffle housing-side annular gap and there flows at least partially along with heat and along the upper Muffelrohr Anlagen, so this forms an allothermal gasification zone for heating, pyrolysis and reduction of fuel to be gasified.
- the hot gas generated in the reactor is further used here for heating the upper muffle tube end receiving the fuel to be gasified, thereby forming an allothermal gasification zone in the upper muffle tube region, which essentially requires no external energy and external heat input, and, secondly Also, the reactor gases are already cooled to the gas outlet, so that the reactor Downstream cooling costs significantly reduced or possibly even completely eliminated.
- the temperature of the gas or of the gas mixture of autothermal and allothermal gases can be adjusted to a desired level, for example to at least 1,050.degree C, which in turn means that the tars contained in the gas can be cracked.
- the gas is thus heated again after the pyrolysis in order to crack the tars.
- the resulting hot gases are then advantageously cooled when flowing through the annular gap, wherein the heat extracted for heating, pyrolysis and reduction of the fuel is used in the muffle tube, as has already been explained above.
- a reactor which also ensures a higher fuel flexibility at higher water content and is also insensitive to a certain fines. In addition, this results in a better scalability of the reactor, as well as a higher cold gas efficiency.
- annular gap does not completely surround the muffle tube runs, but for example, the muffle tube rests on the associated muffle tube housing in a system connection, so that then just no completely circumferential annular gap is formed.
- circumferential annular gap is preferably at least one Flow guide arranged so that the gas flowing into the annular gap a turbulent flow is impressed, resulting in a better heat transfer into the muffle tube inside.
- the at least one flow-guiding element is formed by a gas-conducting spiral spiraling at least partially and / or at least in sections in the annular gap at least around a subregion of the upper muffle tube region.
- a gas-conducting spiral which extends over the entire annular gap and / or upper muffle tube region.
- Such a Gasleitspirale effected in an advantageous manner an excellent uniform heat transfer over the entire muffle tube circumference and over the entire muffle tube length, which is particularly advantageous effect on the reliability of drying, pyrolysis and reduction in the allothermal gasification zone of the upper muffle tube area.
- the gas-conducting spiral can be firmly connected, for example, to an outer wall region of the muffle tube, in particular of the upper muffle tube region.
- the Gasleitspirale is arranged by a stationary in the annular gap, in particular connected to the muffle housing or connected, component is formed, so that the muffle tube, in particular for cleaning and inspection work, relative to the Gasleitspirale displaced or rotatable is.
- the gas-conducting spiral can also be connected directly or indirectly to the grate, in particular be connected to a rotatably mounted grate and thus even be moved, for example, via the grate preferably arranged on the bottom side.
- a particularly stable and inherently rigid configuration of the gas-conducting spiral is achieved in that in the direction of extension adjacent helix regions of the gas-conducting spiral are partially stiffened by supporting elements spaced apart from one another in the helical direction. These support elements may be formed, for example, by support rods having defined low flow resistance. The Spacing can preferably take place in such a way that the individual support elements or support rods are also offset from each other at least partially on the circumference.
- the entire reactor is provided with a thermal insulation, which is preferably formed as an outer insulation, for example of a ceramic layer and a rock wool layer.
- a thermal insulation is ensured in a simple and reliable manner that the heat is maintained in the reactor, for example in the region of the allothermal gasification zone.
- the muffle housing preferably in the region of the upper end of the muffle tube, has at least one gas outlet opening opening into the annular gap. This ensures that the useful gas is withdrawn from the reactor only after complete flow through the annular gap and thus after the desired heat release to the upper Muffelrohr Anlagen.
- the muffle housing preferably has a head-side reactor opening, via which the muffle tube can be inserted into the interior of the reactor.
- the muffle tube can then be suspended and fixed to the muffle housing with at least one muffle tube-side fastening device, for example with a muffle tube flange. This ensures in a simple manner that the muffle tube is a simple from the reactor on or to be removed component, which is for example particularly in cleaning or inspection work of advantage.

- the head part can be fixed by means of a Kopfteilflansches on a mounting flange of the muffle housing, which ensures a stable and reliable and easy to manufacture connection.
- the muffle tube with a head end or upper reactor opening superior Muffelrohrende is received in a head portion into which the fuel metering device, ensures that the metered fuel in a simple and reliable manner directly into the desired Area of the muffle tube passes.
- the muffle tube protrudes beyond the head-side reactor opening with an upper muffle tube end in such a way that the Fuel metering device, preferably a metering screw, directly into the upper end of the muffle tube protruding above the head-side reactor opening opens.
