Definitions
- the invention relates to a method for obtaining high-calorific fuel gases and an apparatus for performing the method.
- a major advantage of gasification over combustion is that the pollutants contained in the starting substance are converted into constituents or into relatively simple chemical compounds in a reducing atmosphere.
- the gas volumes are significantly smaller compared to combustion, so that gas cleaning in gasification compared to combustion can be carried out more easily and cost-effectively with the same objective.
- the gasification of solid, pasty or liquid fuels with the gasification medium air is technically the simplest process and leads to partial oxidation.
- the calorific value of the gas produced is lower than that of the fuel used.
- the Gasification temperatures are typically in the range between 600 ° C and 900 ° C. At these temperatures, tars are produced to a large extent. The method has not been used on a large scale so far, since the removal of the tars from the gas has so far not been adequately controlled for small gasifiers
- the gasification of solid, pasty or liquid fuels with the gasification medium oxygen leads, like the air gasification, to a partial oxidation with a reduction in the calorific value.
- the gasification temperatures are typically around 1600 ° C, so that tar formation is excluded the generation of the required oxygen is associated with high costs and puts too much strain on business calculations.
- Oxygen gasification leads to smaller gas quantities than air gasification, since the gasification medium does not enter an inert nitrogen component
- the gasification of solid, pasty or liquid fuels with the gasification medium water vapor leads to a gas that has a higher calorific value than the fuel originally used.
- the gasification reactor must therefore be supplied with heat from the outside.
- the gasification temperatures are typically between 600 ° C and 900 ° C of tar possible
- the potential is lower than in air gasification.
- Large-scale use has not yet been achieved because, above all, the problem of heat input into the reactor has not been adequately solved.
- the amount of gas in water vapor gasification is between that of air and oxygen gasification. This is then justifies that in water vapor gasification the carbon of the fuel is oxidized to carbon monoxide or carbon dioxide by the oxygen of the water vapor, whereby additional hydrogen is formed.
- the hydrogen generation potential of the water vapor gasification is thus considerably higher than that of air or Sa. uerstoffvergasung
- the combination of an auto- and allothermal process means that the amount of gas rises sharply due to the nitrogen content that is introduced with the air for the partial combustion.
- the partial pressures of the useful gases thus decrease, which adversely affects the subsequent gas cleaning and gas aftertreatment.
- a fluidized bed is a technology that has been tried and tested and widely used for many years. Areas of application are e.g. drying and burning solid materials or sludge.
- the basis of every fluidized bed process is a reactor in which a solids inventory is loosened by inflow from below to such an extent that the individual particles begin to float in the air; the solids inventory is fluidized.
- Partition areas of different fluidization are formed so that there is a circulation of bed material in a stationary bed

- the design of the reaction space can be carried out independently of the geometrical specifications for the heating, so that the overall size of the device according to the invention can be optimized.
- the descending first bed is loosened or slightly fluidized by injection of a gas, which advantageously prevents undesired agglomeration of the solid particles and supports the transport of the bed material.
- the descending first bed is indirectly using a heat exchanger , through which a heating medium flows, heated
- the heating medium can flow pulsatingly when the heat is given off to the descending first bed in the heat exchanger. In this way, the heat transfer from the heat exchanger to the descending first bed is improved

- the shower base 15 delimits the reaction area 3, in which the fluidized bed 2 is formed, next to or below the nozzle base 15 a fume cupboard, not shown in FIG. 1, from which, for example, bed material, stored matter from the fuel, ash and unreacted fuel components can be drawn off.
- Fume can be emitted into the fume cupboard, which on the one hand facilitates the fume cupboard and on the other hand a subsequent reaction of residual constituents of the fuel ensured
- the embodiment shown also comprises a heating area 6, which is separated from the reaction area 3 by a device 9.
- a descending bed 1 made of solid particles is formed in the heating area 6
- Dusenteil 22 may be arranged, flows through the steam that to Improvement of the mass transfer loosened the bed material of the heating zone or weakly fluidized
- the heating zone 6 is a means 8 for the indirect heat supply arranged
- These Warmezuchtein ⁇ chtung 8 may for example be one or more heat exchangers, it is clear that the present invention is not 'in the manner shown in Figure 1 special arrangement of the heat exchanger 12 is limited, but that other arrangements, for example on the wall of the heating area 6, are also conceivable.

- the heat exchanger 12 provided in the heating area can partially consist of resonance tubes 13, in which the heating medium flows in a pulsating manner when the heat is released into the heating area 6.
- the resonance tubes 13 are connected to a combustion chamber (not shown) or another resonance generator to generate the resonance oscillation of the heating medium is done directly by burning a flammable substance with oxygen-containing gas
- the solid particles are heated up separately from the gasification taking place in the reaction space 3. Due to the weak fluidization of the heating area, a slow descending bed 1 is formed there, while due to the strong fluidization of the reaction area 3 there is a rapidly rising fluidized bed 2 forms The arrangement of the heat exchanger 12 in the slow descending bed 1 reduces the strong mechanical abrasion of the heat exchanger which has hitherto taken place in the prior art.
