Description

  The present invention relates to a reformer that generates a hydrogen-containing gas by reforming a raw fuel containing hydrocarbons in the presence of steam, and a steam that evaporates supplied water and supplies steam to the reformer. In a hydrogen-containing gas generation device including a generator, and a reforming control unit that controls a supply amount of raw fuel to the reformer and a supply amount of water to the steam generator, and the hydrogen-containing gas generation device The present invention relates to a method for adjusting the amount of hydrogen-containing gas produced.

  As a device for generating hydrogen used as a fuel gas of a fuel cell, a reformer that generates a hydrogen-containing gas mainly containing hydrogen by reforming raw fuel containing hydrocarbon in the presence of water vapor; A steam generator that evaporates the supplied water and supplies steam to the reformer, and a reforming control means that controls the amount of raw fuel supplied to the reformer and the amount of water supplied to the steam generator There is a hydrogen-containing gas generator.

  When steam reforming of raw fuel is performed in a hydrogen-containing gas generator, prevention of carbon deposition in the reforming catalyst of the reformer, or in the outlet gas of a carbon monoxide converter provided downstream of the reformer In order to keep the CO concentration below a certain value, the equivalent ratio of water vapor to carbon in the raw fuel supplied to the reformer (hereinafter sometimes referred to as “S / C”) is controlled to a certain level or more. There is a need to. However, if water vapor is supplied more than necessary, the fuel that is the source of heat required to generate water vapor is consumed excessively and energy efficiency is reduced, so S / C needs to be controlled within a certain range. Become.

  In order to increase the amount of hydrogen supplied from the hydrogen-containing gas generator to the fuel cell when the fuel cell is started or when the power load is increased, it is necessary to increase the raw fuel supplied to the reformer. At this time, not only the amount of raw fuel supplied to the reformer is increased, but also the amount of water supplied to the steam generator is increased in order to maintain the above-mentioned S / C, and the amount of steam generated is increased. As a result, it is also necessary to increase the amount of steam supplied to the reformer. However, even if supplying the target water amount to the steam generator to supply the target steam amount to the reformer, if it takes time to evaporate all of the target water amount, In some cases, only a smaller amount of water vapor than the target water vapor amount can be supplied to the reformer. Therefore, in the past, taking into account the time required for the amount of steam supplied to the reformer to reach the required amount, when the load increases, a prior increase in the amount of reforming water is performed before the load increase with a predetermined time limit. Is doing.

  For example, in the hydrogen-containing gas generation device described in Patent Document 1, in order to increase the amount of hydrogen-containing gas generated in the reformer, the amount of raw fuel supplied to the reformer and the water supply to the steam generator When both the amount and the amount of fuel are increased, the amount of water supplied to the steam generator is increased and changed before the time when the amount of supply of raw fuel to the reformer is increased.

JP 2003-212505 A

However, if the steam generator cannot supply sufficient heat to evaporate the supplied water, the time until the required amount of water evaporates is not constant. In other words, even if the amount of water supplied to the steam generator is increased and changed a certain time before the time when the amount of raw fuel supplied to the reformer is increased and changed, the time when the amount of raw fuel supplied is increased and changed. However, the required amount of water is not necessarily evaporated, and an error may occur in S / C.
That is, even if the target water amount is supplied to the steam generator in order to supply the target steam amount to the reformer, not all of the target water amount evaporates. In some cases, only a small amount of water vapor can be supplied to the reformer. In this case, since the S / C is not in an appropriate range, problems such as the occurrence of coking in the reformer and the concentration of CO in the hydrogen gas obtained by the reforming process due to insufficient steam as described above. Can occur.

  The present invention has been made in view of the above-described problems, and the object thereof is performed in a hydrogen-containing gas generation device capable of avoiding the occurrence of steam shortage in a reformer and the hydrogen-containing gas generation device. The object is to provide a method for adjusting the amount of hydrogen-containing gas produced.

In order to achieve the above object, the hydrogen-containing gas generator according to the present invention includes a reformer that generates a hydrogen-containing gas by reforming a raw fuel containing hydrocarbons in the presence of steam;
A steam generator for evaporating the supplied water and supplying steam to the reformer;
Reforming control means for controlling the amount of raw fuel supplied to the reformer and the amount of water supplied to the steam generator;
The reforming control unit increases both the amount of raw fuel supplied to the reformer and the amount of water supplied to the steam generator in order to increase the amount of hydrogen-containing gas generated in the reformer. A hydrogen-containing gas generator configured to increase and change the amount of water supplied to the steam generator before the time of increasing the amount of raw fuel supplied to the reformer when changing There,
A pressure value capable of estimating the amount of steam supplied from the steam generator to the reformer is set in a flow path through which water supplied to the steam generator or steam generated by the steam generator flows. Equipped with a pressure detector to detect,
The reforming control unit is configured to increase the amount of hydrogen-containing gas generated in the reformer based on the detection result of the pressure detector after increasing the amount of water supplied to the steam generator. Thus, the timing for increasing and changing the supply amount of the raw fuel to the reformer is determined.

According to the above characteristic configuration, the pressure detector generates a pressure value capable of estimating the amount of steam supplied from the steam generator to the reformer, with water supplied to the steam generator or the steam generator. Detection is performed in a flow path through which water vapor flows. That is, the reforming control means can know the amount of steam supplied from the steam generator to the reformer with high accuracy based on the pressure value detected by the pressure detector. As a result, the reforming control means can control the amount of raw fuel supplied to the reformer and the amount of water vapor to have an appropriate equivalent ratio (S / C).
Therefore, it is possible to provide a hydrogen-containing gas generation device that can avoid the occurrence of water vapor shortage in the reformer.

Another characteristic configuration of the hydrogen-containing gas generation device according to the present invention is provided in the middle of the flow path between the steam generator and the reformer, and includes a flow rate limiting unit that limits the flow rate of the steam,
The pressure detector is to detect a pressure in a flow path through which water supplied to the water vapor generator or water vapor generated by the water vapor generator flows, upstream of the flow rate restricting means.

  According to the above characteristic configuration, the flow rate of the steam flowing from the steam generator to the reformer is limited by the flow rate limiting unit, so that the pressure in the space upstream of the flow rate limiting unit is higher than the flow rate limiting unit. The pressure due to the water vapor generated by the water vapor generator is better represented. As a result, the reforming control means can know the amount of steam supplied from the steam generator to the reformer with higher accuracy based on the pressure value detected by the pressure detector.

Still another characteristic configuration of the hydrogen-containing gas generation device according to the present invention is that the reforming control unit is configured to increase the amount of hydrogen-containing gas generated in the reformer to a target generation amount. When increasing the supply amount of raw fuel to the steam generator to the target raw fuel amount and increasing the supply amount of water to the steam generator to the target water amount,
When the detection value of the pressure detector after increasing the supply amount of water to the steam generator becomes a target pressure value corresponding to the target water amount, the supply amount of raw fuel to the reformer is The point is that it is determined that it is the timing for increasing the target raw fuel amount.

  According to the above characteristic configuration, when the target water amount of water is supplied to the steam generator, the pressure value detected by the pressure detector is less than the target pressure value if the water evaporation amount is insufficient. If the evaporation amount of the water is sufficient, the pressure value detected by the pressure detector becomes the target pressure value. That is, based on the detection value of the pressure detector, it can be known that water vapor having a water vapor amount corresponding to the target water amount supplied to the water vapor generator is supplied to the reformer. As a result, the reforming control means can control the amount of raw fuel supplied to the reformer and the amount of water vapor to have an appropriate equivalent ratio (S / C).

Still another characteristic configuration of the hydrogen-containing gas generation device according to the present invention includes a temperature detector that detects a temperature at a portion where the pressure detector detects a pressure value,
The reforming control unit is configured to correct and convert the detection result of the pressure detector based on the detection result of the temperature detector.

In order to achieve the above object, the characteristic configuration of the method for adjusting the amount of hydrogen-containing gas production according to the present invention includes a reformer that produces a hydrogen-containing gas by reforming raw fuel containing hydrocarbons in the presence of steam. A hydrogen-containing gas generating device comprising a water vapor generator for evaporating supplied water and supplying water vapor to the reformer, and a supply amount of raw fuel to the reformer and the water vapor generator A method for adjusting the amount of hydrogen-containing gas produced by adjusting the amount of hydrogen-containing gas produced in the reformer by controlling both the amount of water supplied,
When the supply amount of raw fuel to the reformer and the supply amount of water to the steam generator are both increased and changed in order to increase the amount of hydrogen-containing gas generated in the reformer, the reforming After increasing the supply amount of water to the steam generator before the time of increasing the supply amount of raw fuel to the steam generator, and after increasing the supply amount of water to the steam generator, The timing for increasing and changing the supply amount of raw fuel to the reformer based on the pressure value in the flow path through which the water supplied to the steam generator or the steam generated by the steam generator flows. The point is to decide.

  According to the above characteristic configuration, when both the supply amount of raw fuel to the reformer and the supply amount of water to the steam generator are increased to increase the amount of hydrogen-containing gas generated in the reformer. The supply amount of water to the steam generator is increased and changed before the time when the supply amount of raw fuel to the reformer is increased and changed. And based on the pressure value in the flow path through which the water supplied to the steam generator or the steam generated by the steam generator flows after changing the supply amount of water to the steam generator, The timing for increasing the supply amount of raw fuel to the reformer is determined. In other words, a pressure value capable of estimating the amount of steam supplied from the steam generator to the reformer is detected in a flow path through which water supplied to the steam generator or steam generated by the steam generator flows. Thus, the amount of steam supplied from the steam generator to the reformer can be known with high accuracy. As a result, the amount of raw fuel supplied to the reformer and the amount of water vapor can be controlled so as to have an appropriate equivalent ratio (S / C).

A hydrogen-containing gas generator according to the present invention will be described below with reference to the drawings.
FIG. 1 is a diagram illustrating a configuration of a fuel cell system including a hydrogen-containing gas generation device. As shown in the figure, the fuel cell system is configured to supply a fuel gas mainly composed of hydrogen, which is generated using a hydrogen-containing gas generation device, to the fuel cell FC so that a power generation reaction is performed in the fuel cell FC. Has been. The hydrogen-containing gas generating device includes a reformer 2, a steam generator 6, and a control device 13 that functions as the reforming control means 13a. In addition, the hydrogen-containing gas generator of this embodiment shown in FIG. 1 includes a desulfurizer 1, a carbon monoxide converter 3, a carbon monoxide remover 4, and a combustor 5.

  The desulfurizer 1 desulfurizes a sulfur compound contained as an odorant in the supplied raw fuel (for example, city gas).

  The steam generator 6 evaporates the supplied water and supplies the reformer 2 with water vapor. Specifically, the combustion exhaust gas discharged from the combustor 5 is supplied to the heat exchanger 8 provided adjacent to the steam generator 6, and the heat of the combustion exhaust gas is transmitted to the steam generator 6. Used for water evaporation. The steam generated by the steam generator 6 is added to the raw fuel after the desulfurization treatment. In addition, the hydrogen-containing gas generation apparatus of the present embodiment also includes an electric heater H that can heat the steam generator 6. That is, the steam generator 6 is configured to evaporate the supplied water by using heat obtained from at least one of the heat exchanger 8 and the electric heater H.

  The combustor 5 burns a mixed gas of combustible gas and oxygen gas to generate combustion heat. As the combustible gas, exhaust fuel gas discharged from the fuel cell FC (a gas containing hydrogen that has not been used in the power generation reaction) can be used.

  The reformer 2 reforms the raw fuel in the presence of steam to generate a hydrogen-containing gas containing hydrogen as a main component. Specifically, the reformer 2 steam-reforms the raw fuel by using the combustion heat generated in the adjacent combustor 5 to form hydrogen as a main component and a by-product. A reformed gas containing carbon oxide and carbon dioxide is generated.

  The carbon monoxide converter 3 performs processing so as to reduce carbon monoxide contained in the gas generated in the reformer 2. Specifically, in the carbon monoxide converter 3, carbon monoxide contained in the reformed gas generated in the reformer 2 reacts with water vapor, and the carbon monoxide is converted into carbon dioxide. Is done.

The carbon monoxide remover 4 removes carbon monoxide remaining in the reformed gas after the shift treatment discharged from the carbon monoxide shifter 3. For example, in the carbon monoxide remover 4, carbon monoxide remaining in the reformed gas after the shift treatment is oxidized and removed by oxygen in the newly added air. As a result, a hydrogen-rich fuel gas with a very low carbon monoxide concentration is produced.
The reformed gas after being treated by the carbon monoxide remover 4 is supplied to the fuel cell FC and used for a power generation reaction.

In the fuel cell system illustrated in FIG. 1, the power generated by the fuel cell FC is configured to be supplied to the power conditioner 9.
The control device 13 controls operations of various devices provided in the fuel cell system. Specifically, the reforming control means 13 a, which is a function of the control device 13, controls the amount of raw fuel supplied to the reformer 2 and the amount of water supplied to the steam generator 6. The supply amount of the raw fuel to the reformer 2, that is, the supply amount of the raw fuel to the desulfurizer 1 can be adjusted by a raw fuel flow rate adjustment valve 10 as a flow rate adjusting means provided on the upstream side of the desulfurizer 1. is there. Further, steam is supplied to the reformer 2 via a steam supply path. This water vapor is generated by the water vapor generator 6. Water is supplied to the steam generator 6 through a water supply path. The amount of water supplied to the steam generator 6 can be adjusted by a pump 11 serving as a water supply amount adjusting means provided on the upstream side of the steam generator 6. The operations of the raw fuel flow rate adjusting valve 10 and the pump 11 are controlled by the reforming control means 13a.
The control device 13 controls the operation of the power conditioner 9, for example, the output current of the fuel cell FC.

  The hydrogen-containing gas generation device includes a flow rate limiting unit 7 provided in the middle of the flow path between the water vapor generator 6 and the reformer 2 to limit the flow rate of water vapor. For example, an orifice can be used as the flow restriction means 7. In addition, a flow rate limiting means 7 that limits the flow rate of water vapor with a valve whose opening degree can be adjusted may be used.

  In addition, the hydrogen-containing gas generation device generates a pressure value that can estimate the amount of steam supplied from the steam generator 6 to the reformer 2 in the water supplied to the steam generator 6 or the steam generator 6. A pressure detector 12 is provided for detection in a flow path through which the water vapor flows. In the present embodiment, the pressure detector 12 is provided upstream of the water vapor generator 6, that is, between the pump 11 and the water vapor generator 6. By providing the pressure detector 12 at this position, the pressure in the water vapor generator 6 is reflected in the detection result of the pressure detector 12.

  Furthermore, in the present embodiment, the pressure detector 12 is a pressure in a flow path upstream of the flow rate restricting means 7 and through which water supplied to the steam generator 6 or steam generated by the steam generator 6 flows. Is provided at a position to detect. The position where the pressure detector 12 is provided is that the flow rate of water vapor flowing from the steam generator 6 to the reformer 2 is restricted by the flow restriction means 7, so that the detected pressure value is the flow restriction means 7. This is a position that better represents the pressure due to the steam generated by the steam generator 6 on the upstream side. As a result, the reforming control means 13a can know the amount of steam supplied from the steam generator 6 to the reformer 2 with higher accuracy based on the pressure value detected by the pressure detector 12.

  Further, in order to further improve the accuracy of the detection result by the pressure detector 12, the detection result of the temperature detector 14 can be used. Specifically, the hydrogen-containing gas generation apparatus of the present embodiment includes a temperature detector 14 that detects the temperature at a portion where the pressure detector 12 detects the pressure value, and the reforming control means 13a includes the temperature detector. Based on the detection result of 14, the detection result of the pressure detector 12 is corrected and converted. It should be noted that it is possible to appropriately set which correction calculation formula is used to correct the detection result of the pressure detector 12 with the temperature.

  In the present embodiment, the reforming control means 13 a supplies the raw fuel to the reformer 2 and the water to the steam generator 6 in order to increase the amount of hydrogen-containing gas produced in the reformer 2. When both are increased, the amount of water supplied to the steam generator 6 is increased before the time when the amount of raw fuel supplied to the reformer 2 is increased. In particular, when the reforming control means 13a increases the production amount of the hydrogen-containing gas in the reformer 2, the detection result of the pressure detector 12 after changing the supply amount of water to the steam generator 6 is increased. Based on the above, the timing for increasing the supply amount of the raw fuel to the reformer 2 is determined.

FIG. 2 is a timing diagram for explaining the transition of the operating state of each device when the amount of hydrogen-containing gas produced in the reformer 2 is increased. Specifically, after the output increase command of the fuel cell FC is generated, “the amount of water supplied to the steam generator 6”, “the detection value of the pressure detector 12” adjusted by the pump 11, raw fuel Changes in “the amount of raw fuel supplied to the desulfurizer 1” adjusted by the flow rate control valve 10 and “the output current of the fuel cell FC” adjusted by the power conditioner 9 are shown.
Hereinafter, with reference to FIG.1 and FIG.2, the hydrogen-containing gas production amount adjustment method performed in a hydrogen-containing gas production | generation apparatus is demonstrated.

  When a command to increase the output of the fuel cell FC is generated at time t0 shown in FIG. 2, the reforming control means 13a of the control device 13 sets the generation amount of the hydrogen-containing gas in the reformer 2 as the target generation after time t0. In order to increase the amount, the amount of raw fuel supplied to the reformer 2 is increased to the target raw fuel amount, and the amount of water supplied to the steam generator 6 is increased to the target water amount. Take control. However, at time t0, the reforming control means 13a first sets the target amount of water supplied to the steam generator 6 without increasing the supply amount of the raw fuel to the reformer 2 to the target raw fuel amount. Starting to increase the amount of water, the adjustment for increasing the amount of water supplied to the steam generator 6 to the target water amount at time t2 is completed.

  Further, when the supply amount of water to the steam generator 6 starts to increase at time t0, the amount of steam generated in the steam generator 6 also starts to increase with a certain time delay, so that the pressure detector 12 at time t1. The detected pressure value also begins to rise. At time t3, the pressure value detected by the pressure detector 12 becomes a target pressure value corresponding to the target water amount. FIG. 3 is a graph showing the relationship between the target water amount and the target pressure value, that is, when the target water amount of water is supplied to the steam generator 6 and all of the target water amount is evaporated, the pressure detector 12 is a graph showing how much pressure value is detected at 12; That is, when the pressure value detected by the pressure detector 12 reaches the target pressure value shown in FIG. 3 after increasing the target water amount, all the water of the target water amount is evaporated to the reformer 2. It can be considered that the target water vapor amount is supplied. In the present embodiment, the relationship between the target water amount and the target pressure value as shown in FIG. 3 is stored in advance in a storage unit built in the control device 13 or a storage device that can be read by the control device 13. It is assumed that the reforming control means 13a of the apparatus 13 reads the relationship between the target water amount and the target pressure value as appropriate.

  At time t3, the reforming control means 13a of the control device 13 determines that the detected value of the pressure detector 12 after increasing the amount of water supplied to the steam generator 6 to the target water amount corresponds to the target water amount. When the pressure value is reached, the supply amount of the raw fuel to the desulfurizer 1 is increased and changed to the target raw fuel amount. As a result, steam reforming of the raw fuel is performed in a state where the equivalent ratio (S / C) of water vapor to carbon in the raw fuel supplied to the reformer 2 is maintained in an appropriate range. Thereby, generation | occurrence | production of problems, such as generation | occurrence | production of coking in the reformer 2, and the density | concentration of CO in hydrogen gas obtained by a reforming process by water vapor | steam shortage, can be suppressed.

  At time t3, the control device 13 controls the operation of the power conditioner 9 to increase the output current of the fuel cell FC to the target current value in accordance with the increase in the supply amount of the raw fuel to the desulfurizer 1. Change.

  As described above, in the present embodiment, the pressure detector 12 uses the water pressure supplied to the steam generator 6 or the pressure value that can estimate the amount of steam supplied from the steam generator 6 to the reformer 2. Detection is performed in a flow path through which water vapor generated by the water vapor generator 6 flows. That is, the reforming control means 13a of the control device 13 can know the amount of steam supplied from the steam generator 6 to the reformer 2 with high accuracy based on the pressure value detected by the pressure detector 12. . As a result, the reforming control means 13a can control the amount of raw fuel supplied to the reformer 2 and the amount of water vapor so as to have an appropriate equivalent ratio (S / C).

For example, in the above embodiment, the configuration in which the heat exchanger 8 and the electric heater H are provided in order to heat the steam generator 6 has been described, but the configuration in which the electric heater H is not provided may be used. Moreover, in the said embodiment, although the structure which supplies the exhaust fuel gas discharged | emitted from the fuel cell FC to the combustor 5, and combusts was demonstrated, other combustibility, such as city gas used for the said combustor 5, as said raw fuel The configuration may be changed such that gas is supplied and burned.
In addition, a configuration change in which the installation position of the pressure detector 12 and the temperature detector 14 is changed, or a configuration change in which the flow rate limiting unit 7 and the temperature detector 14 are not provided may be performed.
