Abstract

A burner 4 for a reformer 3 comprises at least a partial feedback 6 of a reformate gas and/or a partial feedback 8 of an anode gas from a fuel cell 2 to the burner 4 and feedback 5 of waste gas from the burner 4 back to the burner 4, which prevents backfires and the flame going out. A sensor and/or actuator unit 18 may be provided in the feedback 6 of the reformate gas so that the burner 4 can be selectively supplied with additional energy rich reformate gas, which has a higher flame velocity than a hydrocarbon fuel such as petrol being supplied to the burner 4 via a supply line 13. Sensor and/or actuator unit 18 may also be located in a connection 7 where feedback 6 of the reformate gas and feedback 8 of the anode gas combine. Waste gas from the burner 4 may also pass back to the burner 4 via a sensor and/or actuator unit 16, which may be combined with a quantity control 17 that is dependent on flow velocity or flame velocity in the burner 4 of the reformate gas and/or the anode gas fed back to the burner 4. Fuel may be fed to the reformer 3 by a separate supply line 14.

Description

"Burner for a reformer in a fuel-cell system" Fuel cells or fuel-cell
systems require, for their operation, hydrogen that is preferably reformed from hydrocarbon. Reformers are used for reforming the hydrocarbon. Energy is generally necessary for the reforming process that proceeds therein. Said energy can be fed to the reformer internally and/or externally. In the case of the external heat supply, the reformer is heated by a conventional premix burner.
In the case of the internal heat supply, said energy can be produced by means of exothermic reactions, for example by partial oxidation of the reactant inside the reactor. For the start-up phase, however, an external heat supply is additionally necessary even in the case of reactors having an internal heat supply.
In order to be able to supply this additional energy to the reformer, the burner is connected to the reformer so that the heat produced by the burner can heat the reformer to such an extent that the reforming reactions can proceed.
The burner is supplied with fuel, advantageously with the same fuel with which the reformer is fed.
In this connection, this means, therefore, hydrocarbons such as, for example, petrol. The burner is adjusted in such a way that it ensures a stable operation at high efficiency as a function of the flame velocity of the hydrocarbon supplied and of the air needed for combustion or of the oxygen present in the air.
In the start-up phases of the fuel-cell system and of the reformer, the reforming of the fuel to hydrogen produces a reformats gas that still comprises a comparatively low proportion of hydrogen and that additionally also still contains high values of carbon monoxide. Said reformats gas having a low proportion of hydrogen and a high proportion of carbon monoxide can still not be fed to the fuel cell since the latter is unsuitable for operation with such a mixture.
Since, however, the hydrogen produced is a high-quality fuel and since it is desired to achieve as good as possible an efficiency for the system, this reformate is collected from the warm-up phase. An attempt is made to feed this high-quality energy medium to the reforming process again so that the losses are thereby reduced.
Provision is additionally made that the anode residual gas of the fuel cell is likewise fed during operation via a burner to the reforming process.
In a further operating state, namely in the case of a severe change in load, it may likewise occur that reformate gas is produced that does not satisfy the requirements of the fuel cell or that too much reformate is produced. Said reformats gas is also fed again to the reforming operation in the manner described above.
Owing to the fact that the flame velocity of the hydrogen is substantially greater than the flame velocity of the hydrocarbon, conventional flame burners can be operated only with an exactly defined proportion of hydrogen in addition to the hydrocarbon. If the proportion of hydrogen exceeds a certain ratio with respect to the fuel, a backfire in which the flame goes out occurs in the burner.
The burner is consequently no longer operational and precautions have to be taken to start up the burner again in an appropriate manner.
To avoid such events, two burners would have to be used for a reformer for the utilization of Hz-rich, partly reformed gas in the start-up phase so that one burner burns hydrocarbon and the second burner the additionally accumulating, already partly reformed hydrocarbon-rich gas.
This results, however, in an increased space requirement and, additionally, also in an increased financial and technical expenditure that reduces the profitability of the fuel-cell system.
Object and advantages of the invention The object of the present invention is therefore to develop a burner according to the preamble of Claim 1 in such a way that the risk of a backfire during its operation is reduced or completely eliminated.
This object is achieved by the technical teaching of Claim 1.
Further features for the advantageous performance and development of the invention emerge from the subclaim.
According to the invention, a burner according to the preamble of Claim 1 is now developed in such a way that feedback to the burner is provided for the burner waste gas. The feedback of the burner waste gas may reduce the flame velocity of the mixture in the burner or it is possible to increase the flow velocity in the burner in such a way that the mixture of the additionally added hydrogen gas, which has a markedly higher flame velocity than the hydrocarbon, can no longer burn so rapidly that a backfire or a so-called backflash takes place in the burner with the above-specified disadvantages.
That is to say, the feedback according to the invention of the burner waste gas makes it possible to burn with a single burner both hydrocarbons and additionally added fuels having markedly higher flame velocity at the same time.
In addition, in a particular embodiment of the present invention, provision may be made that the burner can burn at least two fuels having different flame velocities.
Consequently, both the reformate gas produced in the start- up mode of the reformer and having a high but insufficient proportion of H2 for the operation of the fuel cell and anode residual gas that is recovered again at the outlet of the fuel cell can be fed directly to the burner.
For the correct operation of the burner, provision can therefore be made in a design modified with respect thereto that a quantity control unit is fitted for the waste gas and/or reformats gas fed back into the burner.
In such an embodiment, provision may also be made, for example, that the quantity control unit is dependent on the flow velocity of the waste gas fed back into the burner. In a further embodiment, provision may, for example, be made that the quantity control unit is dependent on the flame velocity of the reformats gas and/or an anode residual gas fed back into the burner.
As a result, it becomes possible to modify the combustion in the burner either by means of regulating the flow velocity of the burner waste gas or by means of regulating the flame velocity of the additionally supplied fuel having the higher flame velocity, which, in this case, is as a rule the reformed hydrogen.
In a further embodiment of the present invention, provision can be made that the quantity control unit is dependent on the flow velocity, prevailing in the burner, of the reformate gas and/or the anode residual gas fed back into the burner.
In addition, a quantity control unit may, for example, be provided that determines the parameters in the burner directly. In the case of the two embodiments specified previously, it is possible, for example, that the quantity control unit determines the parameters outside the burner.
In a further embodiment, provision may be made that a sensor unit and/or actuator unit is fitted in the feedback for the waste gas of the burner. At that point, for example, the quality and the quantity of the fed-back waste gas of the burner can be determined and modified in collaboration with the quantity control unit.
As a result, it is, for example, possible that, depending on the composition of the waste gas and of the flow velocity prevailing in the burner, more or less waste gas can be fed back into the burner in order to achieve as optimum as possible a flame velocity in the burner.
In a further embodiment, provision is made that a sensor unit and/or actuator unit is provided in the feedback for the hydrogen-rich reformate gas. As a result, a quantitative and qualitative monitoring of the supply of reformats gas to the burner can, for example, be performed in turn. The corresponding parameters can be passed, for example, to the quantity control unit or also transmitted from the latter to the corresponding sensor and actuator units for hydrogen-rich reformate gas or for feedback of the waste gas of the burner.
In a further embodiment, provision may be made that the burner is constructed as a flame burner. In this connection, provision may also be made, for example, that a line carrying fuel is fitted for the operation of the burner. In a particular embodiment, provision may be made in this connection that the fuel is hydrocarbon.
Fuel can therefore optionally be fed separately from the supply of the reformer in the line carrying fuel provided for the operation of the burner. However, hydrocarbon may also be supplied that is fed via a line connected to the supply line for the reformer.
As a result of these features, it is possible to provide only a single burner for a reformer to produce the reaction temperature in the reformer. For the reforming of fuel, preferably for a fuel cell, having at least partial feedback of the reformate gas and/or an anode residual gas into the burner, more or less burner waste gas can be fed back into the combustion chamber depending on the fed-back quantity of the hydrogencontaining reformate gas and/or of the fed-back anode residual gas in order, in this way, to reduce the flame velocity or to increase the flow velocity in the burner so that a backfire in the burner due to the high flame velocity of the added hydrogen component is therefore successfully prevented.
Exemplary embodiment of the invention An exemplary embodiment of the invention is shown in the accompanying drawing and is explained in greater detail below by reference to the description of the figure.
The accompanying figure shows a fuel-cell system 1 comprising a fuel cell 2, a fuel reformer 3 and the burner 4 according to the invention.
The burner 4 heats the reformer 3, which delivers reformed hydrogen to the fuel cell 2 via the line 10. The proportion of hydrogen not converted by the fuel cell 2 is recovered again as anode residual gas via the feedback 8 and fed via the connection 7 and the feedback 6 to the burner 4.
A bifurcation 9 is shown in the line 10. Hydrogen-rich reformate gas can be tapped from the latter via the feedback 6 and fed to the burner 4 via the sensor unit and/or actuator unit 18. Thus, the burner 4, which is supplied with fuel via the line 13 for the purpose of the basic supply, can additionally be supplied with energy-rich reformate gas.
Said energy-rich reformate gas has, however, a markedly higher flame velocity than the basic fuel. To avoid backfires, a waste gas feedback for the burner 4 is provided according to the invention. The waste gas of the burner 4 is at least partially collected for this purpose and fed back to the burner itself as a function of the situations induced by operation.
This may take place, for example, via a sensor unit and/or actuator unit 16 that may be situated, for example, in the feedback 5 for the waste gas of the burner 4. In the diagram shown, the feedback 5 is connected to the waste-gas line 12 of the burner 4 via a bifurcation 11.
In the exemplary embodiment, a quantity control unit 17 is additionally shown together with said sensor unit and/or actuator unit 16. The quantity control unit 17 may, however, be disposed in principle at any desired point in the fuel-cell system 1 suitable for the purpose.
The air or oxygen is fed to the burner 4 via suitable openings. In a confined space, it may, however, be advantageous that a point situated at a distance from the burner 4 is utilized to collect air or oxygen and feed it to the burner by means of line 15.
The reformer 3 is supplied with fuel by means of a line 14 in order to obtain hydrogen in the reform process in a known way. The reformed hydrogen is then fed via the line 10 to the fuel cell 2.
In the start-up mode of the reformer 3 or, alternatively, in the event of load change, the hydrogen-rich reformate gas unsuitable for the fuel cell 2 is split off at the bifurcation 9 and passed to the sensor unit and/or actuator unit 18 via the feedback 6. In this process, for example, both the quantity and the quality of the reformats gas passed through can be determined. This volumetric flow may additionally be modified by using suitable sensor means.
The arrangement of the sensor unit and/or actuator unit 18 may, however, also be disposed, for example, directly in the connection 7 for combining the feedbacks 6 and 8. In this connection, provision could, for example, also be made that both the feedback 8 and the feedback 6 are monitored or modified by said sensor unit and/or actuator unit 18.
In the cases in which the reformats gas does not now have the quality that the fuel cell 2 requires for its satisfactory operation, it is fed to the burner 4 to improve the overall efficiency. For this purpose, provision is made, according to the invention, to operate the burner 4 by means of qualitatively and/or quantitatively controlled feedback of its waste gas in such a way that backfire cannot take place in the burner 4.
