- Literature for circulating fluidized bed in the composite system which is a component of this application, can be taken from the following literature: "Decentralized electricity and heat generation based on biomass gasification", R. Rauch, H. Hofbauer, lecture University of Leipzig 2004.
- Literature for combination fixed bed which is part of this application, can be taken from the following literature: 30 MV Carbo V Biomass Gasifier for Municipal CHP; The CHP Project for the City of Aachen, Dr Rudioff; Lecture Paris, October 2005
- gasification takes place in two stages.
- the biomass is split at 500 ° C into its volatile and solid components.
- the result is a tar-containing gas and additionally "charcoal".
- the gas is burned at temperatures of more than 1200 0 C, with the tars disintegrate in C02 and H2. With the gentle flue gas and the Charcoal is then produced a CO and H2-containing product gas.
- the fluidized bed gasifiers can be subdivided into two processes, which differ in the heating of the fluidized bed, the circulating fluidized bed gasifier and the stationary fluidized bed gasifier.
- Literature for desulfurization in a fluidized bed gasification which forms part of this application can be found in the following literature: Gasification of Lignite and Wood in the Lurgi Circulating Fluidized Be Gasifier; Research
- the management of the fluidized fluidized bed material requires a targeted control and regulation of the steam circulation in the sense of a mammoth pump movement to increase the heat and Substance exchange and to improve the
- the mammoth pump is a conveyor organ in which
- Nozzles in piping or a stirred tank is promoted.
- the injected gas causes a reduction of
- the object of the invention is to provide a method and a device which optimize fluidized bed gasification.
- the advantage compared to the fixed-bed gasifier and the circulating fluidized bed is the lack of pronounced temperature and reaction zones.
- the fluidized bed consists of an inner bed material. This ensures a simultaneous sequence of the individual partial reactions and a homogeneous temperature (about 800 ° C).
- the process is virtually depressurised (up to a maximum of 0.5 bar) and is therefore technically easy to implement. It is characterized by a high degree of economy.
- the acquisition costs are among the aforementioned carburetor types.
- the starting point for further use as fuel is the medium-calorific gas from the bio-synthesis gas plant (based on renewable raw materials), which after dedusting and scrubbing of condensable hydrocarbons (oil quench) via a turbo compressor to about 20 bar compressed and through the following process steps can be refined:
- the synthesis gas-based process of the present invention is capable of producing 100to biomass 23to high-grade fuel.
- the method according to the invention is characterized in that the movement of the fluidized bed can be specifically controlled and regulated by means of jet nozzles.
- the thus achievable macro-flow of the fluidized bed which is similar to the Mammutpumpenroz, serves to increase the reaction zone for flash pyrolysis and increasing the residence time of the primary pyrolysis coke to increase the heat and mass transfer.
- the voluminous biomass which is introduced into the lower part of the steam converter, accelerated, so that the reaction path, and thus the effective reactor volume for primary reaction for this reaction, by a factor of 2 to 4 increases.
- the motive nozzle optimizes the increase in the yield of CO and H2 as primary products of the steam conversion, while reducing the yield of methane and higher hydrocarbons.
- the cold gas efficiency is increased.
- the use of one or more steam jet conveyors has the task to minimize the amount of steam required for fluidization and to replace part of the steam by recycled ⁇ ynthesegas, or to increase the heat input by material heat conduction from the field of pulse burners.
- the unpurified synthesis gas is enriched with carbonaceous particulate matter due to the technology used.
- This dust is in a multi-stage Cleaning system consisting of cyclone, multicyclone and
- Fine filter Fine filter, deposited.
- Dust gravimetrically or by means of propulsion jet nozzle is fed back into the fluidized bed.
- Fig. 1 shows the vapor conversion in the fluidized bed movement by steam jet conveyor and motive nozzle.
- Fig. 2 shows the vapor conversion fluidized bed motion by steam jet conveyors and motive nozzles.
- FIG. 1 shows a carburettor 11 with impulse burners 12 which are arranged in the middle region of the carburetor 11 in order to form a fluidized bed or a fluidized bed in this region, which are preferably designed to be stationary.
- the Number of pulse burners can be determined variably. There are both one and two or more conceivable.
- Starting materials 14 are introduced in the region of the pulse burner 12.
- feedstocks can be biomass and other substances, such as lignite or secondary raw materials (such as municipal waste, sewage sludge, waste from the food industry, etc.)
- the biomass is gasified in the fluidized bed, which consists of inner bed material in the range of about 800 ° C.
- Die Impulsbrenner Q means heat flow and means the reaction enthalpy (ie the calorific value) of the fuel gas used as fuel gas next to the synthesis gas produced in the reformer (product gas) a variety of fuel gas streams (from propane to natural gas and similar gases ) can be used, so that in particular in a plant network of this pulse burner for the combustion of so-called off-gases, which are as it were produced as by-products in syntheses such as methanol synthesis, can be used and thus contributes to increasing the efficiency of an entire system.
- This fuel gas comes in normal operation as a branch of the own production, that is the refining of the biomass to a new product: heating gas.
- the dust components are separated.
- the return can be done at different locations.
- filters in particular fine filters, which may be formed as a downstream battery of sintered metal filters.
- a cyclone is connected downstream, wherein via a dust separation 18, a return can be done below or above the pulse burner.
- the additive hydrated lime or the like can be supplied both in the cyclone and in the multicyclone.
- the synthesis gas is supplied in parallel or serially to a series of fine filters.
- the residues of the fine filters and the multicyclone are collected in a dust separator 18, 19, and returned to the reactor at different points, as already described above.
- the separated dust above or below the pulse burner can be supplied.
- the dust can also be injected through a motive nozzle Parts of the cleaned or partially cleaned
- Synthesis gases are returned to the fluidized bed.
- a steam jet conveyor 3 is used, which introduces the synthesis gas in the steam. It can be clearly seen from FIG. 1 that the synthesis gas is returned after the first dust separation, thus in this case it is still a synthesis gas enriched with fine dust residues.
- a motive nozzle 15 is used, which is controlled by a controller 20 to inject the water vapor and to keep the fluidized bed in motion.
- Another valve 17 serves to supply steam, with the steam jet conveyor being bypassed. By the controller 21, the supply of superheated steam is determined.
- FIG. 2 shows a fluidized bed movement 1 controlled by motive nozzles and the motive nozzle with supply of the propellant.
