Definitions
- the invention relates to an assembly for producing a hydrogen-containing gas.
- Hydrogen-containing gas there are various possible uses, such as in a fuel cell, as fuel for an internal combustion engine or for regeneration of an exhaust gas purification system, such as an NGySpeicher catalyst or particulate filter in the exhaust system of a diesel or lean mixture engine.
- Hydrogen-containing gas may be generated from a fuel-air mixture by means of a reformer (eg, a so-called POX catalyst or an autothermal reformer) by decomposing the mixture into a hydrogen-enriched gas in a catalyst of the reformer.
- a reformer eg, a so-called POX catalyst or an autothermal reformer
- the invention provides an assembly for generating a hydrogen-containing gas, which is characterized by a particularly low energy consumption.
- an assembly for producing a hydrogen-containing gas comprising a reforming device with a fuel supply and a gas supply, an evaporation unit arranged upstream of a catalyst of the reforming device with a heating element arranged in a chamber for evaporating fuel, wherein the steam in the Gas flow is passed, as well as a chamber upstream preheater for the fuel in the form of a heat exchanger.
- the fuel is mainly heated by the heat exchanger or even completely evaporated and the heating element used only when needed, such as in a startup phase of the internal combustion engine or the reforming device, in which the heat exchanger can provide no or not the required energy.
- the energy already existing in the system is primarily used, only in case of need is the additional heating element used.
- the gas supply is in particular an air supply.
- the heating element is an electrical heating element, in particular a glow plug. This is available as a mass-produced particularly favorable.
- the heat exchanger is exposed according to one embodiment of the gas flow through which the reforming device. It can the
- Heat exchanger may be positioned in the reformer itself or downstream of the reforming device at a suitable location in the hydrogen-containing gas stream, ie in the exhaust gas of the reforming device.
- the heat exchanger is downstream of the catalyst in the
- Reforming device or positioned in the catalyst, which is e.g. is a partial oxidation catalyst (POX).
- POX partial oxidation catalyst
- the heat exchanger can also be positioned in the area of this fuel cell, especially upstream of a cold fuel cell or downstream of a hot fuel cell.
- the heat exchanger is preferably positioned in the associated exhaust gas line of an internal combustion engine.
- the heat exchanger can be arranged at any point where the required energy is available.
- At least one control device is provided which controls the heating element for dispensing the amount of heat still necessary for evaporation, in particular as a function of fuel mass flow and temperature. This results in a particularly efficient system. If the heating element is an electrical heating element, the control device controls its power supply.
- a temperature sensor should be provided, which is coupled to the control device, wherein based on the data detected by the temperature sensor, the amount of heat is determined, which still has to be supplied to the fuel.
- an ignition device for the reforming device supplied fuel-air mixture is provided between the evaporation unit and the reforming device.
- the ignition device may be, for example, a spark plug, an arc or a ceramic glow plug (MIMS).
- FIG. 1 is a schematic representation of an assembly according to the invention for producing a hydrogen-containing gas
- FIG. 2 shows a perspective view of the heating device for the fuel designed as an intermediate flange insert.
- An assembly 10 for generating a hydrogen-containing gas comprises a reforming device 12, the gas supply 14 in the form of a
- Air supply and a fuel supply 16 has.
- an evaporation unit 18 is arranged, which has an in a chamber 20 positioned electrical heating element 22, here a glow plug.
- a ceramic glow plug MIMS
- the evaporation unit 18 is thus with respect to the
- Reforming device 12 by flowing gas flow upstream of a
- Catalyst 26 of the Reformierungsemcardi 12 which is in particular a partial oxidation catalyst (POX).
- a preheater for the fuel in the form of a heat exchanger 24, which in the embodiment shown is positioned in the reformer 12 downstream of the catalytic converter 26.
- the heat exchanger 24 is thus exposed to the gas stream which flows through the reforming device 12. Notwithstanding the arrangement shown, the heat exchanger 24 may also be positioned in the region of a fuel cell downstream of the reforming device 12. If the assembly 10 according to the invention is used in combination with an internal combustion engine, be it to provide hydrogen-enriched fuel for the internal combustion engine or to generate a reducing agent for the regeneration of an associated emission control system, the heat exchanger 24 may also be positioned in the region of the internal combustion engine, in particular in the internal combustion engine exhaust system.
- control device 28 which with a
- Temperature sensor 30 is arranged, which is arranged between the heat exchanger 24 and the heating element 22 in the fuel supply 16.
- the reforming device 12 is supplied via the gas supply 14 (possibly preheated) fresh air and the fuel supply 16 (or the evaporation unit 18) vaporous fuel, which are mixed together.
- the catalytic converter 26 a partial oxidation of the fuel takes place, in which hydrogen is released.
- the evaporation of the initially liquid fuel takes place for the most part in the heat exchanger 24, wherein in the Control device 28 on the basis of the temperature sensor 30 detected data and in dependence on the mass flow in the fuel supply 16, the amount of heat is determined, which is possibly still necessary for complete evaporation of the fuel.
- control device 28 controls a power supply of the heating element 22; the fuel reaching the chamber 20 in the liquid state is then completely evaporated by the heating element 22 before it enters the reforming device 12.
- the evaporation unit 18 is therefore used in particular in a cold start phase of the reforming device 12.
- an ignition device 32 for the fuel-air mixture such as a spark plug, can optionally be provided between the evaporation unit 18 and the reforming device 12 (or the catalytic converter 26) , an electric arc or a ceramic glow plug.
- the reforming device may be a so-called autothermal reformer which, in addition to a partial oxidation section, has a steam reforming section and a steam feed.
- a coiled in the warm air flow, coiled heat exchanger 24 heats the fuel.
- the air flow in turn can e.g. be heated by the energy downstream of the reforming device or the fuel cell or the catalyst via further heat exchangers.
- the embflanscheinsatz 34 may possibly also the reforming device 12 are integrated.
