Definitions

  • Combustion device for the combustion of hydrogen and method for carrying out the combustion
  • the invention relates to a combustion device and a method for burning hydrogen with oxygen.
  • Combustion devices of this type are used, inter alia, in power plants in which steam turbines are used to drive generators to generate electricity.
  • a steam capacity is provided with the combustion device.
  • the possibility of using hydrogen efficiently improves the sustainability of energy production.
  • EP0452839B1 discloses a typical combustion device which initially has the shape of a cylinder.
  • hydrogen and oxygen are supplied at the upstream end, which burns in the combustion chamber of the combustion device.
  • the resulting steam is discharged downstream and is thus available, for example, to the steam turbine.
  • the wall of the combustion device be specially cooled.
  • a double-walled cylinder is used for this purpose, with a tube bundle being arranged on the inside. Feed water is here through the Pipe bundles and, after a deflection, injected into the combustion chamber through the double-walled cylinder.
  • An embodiment of a combustion device is known from DE112018000670T5, in which oxygen and hydrogen are supplied to a burner.
  • the burner is arranged in a flow channel in such a way that the hot steam produced by the combustion flows through the center of the flow channel.
  • cold steam is supplied to the flow channel. Similar to a flow pump, the cold vapor is entrained by the hot vapor produced by the combustion. The cold steam thus surrounds the hot steam, with the cold steam mixing with the hot steam as the distance increases, and an average temperature that is uncritical for the materials used is established.
  • Combustion device for burning hydrogen known.
  • it is proposed to carry out the combustion over several stages.
  • excess oxygen is supplied, so that the hydrogen supplied at the same time burns completely.
  • the excess of oxygen leads to a lowering of the resulting temperature in the first combustion to an acceptable level compared to a stoichiometric combustion.
  • a turbine is first used to reduce power and cool the combustion product from the water formed during combustion and the remaining oxygen.
  • the object of the present invention is therefore to enable combustion of hydrogen with oxygen, in which an advantageous controlled process is possible and in which a long service life of the combustion device can be guaranteed and, in particular, can still be designed simply in terms of construction.
  • Power generation device is specified in claim 4.
  • a method for solving the problem is specified in claim 5.
  • Advantageous embodiments are the subject matter of the dependent claims.
  • the new concept according to the invention is based on the staged combustion, with the exception of the last stage of the two reactants is present in excess.
  • each reaction section comprises a combustion chamber and an adjoining transition section.
  • the combustion chamber preferably has a tubular shape, in which the reactants are fed in on the upstream side.
  • Other known designs of other combustion chambers can also be used.
  • a reactant is supplied through a side wall.
  • the combustion chamber obviously has to be designed in such a way that the temperatures occurring during combustion do not damage the combustion chamber.
  • the combustion chamber should obviously be designed to be open on the downstream side in order to ensure that the water vapor generated and any unburned portion of the first reactant can escape.
  • the transition section is also designed as an open channel.
  • the dissipation of energy between the stages for example through turbines, is essentially dispensed with here.
  • the shape of the transition section is irrelevant here, a preferably tubular shape analogous to the combustion chamber also being selected.
  • the transition section connects a preceding combustion chamber to a following combustion chamber (except for the obvious, the last combustion chamber subsequent transition section).
  • the transition section provides a free flow cross-section between the combustion chambers. In this regard, it is irrelevant whether, for example, static elements for turbulence are arranged in the transition section.
  • a first supply device is initially required, from which the first reactant can be supplied.
  • a second supply device is required, from which the second reactant can be supplied.
  • the first reactant is hydrogen
  • oxygen is supplied by the second supply device and, conversely, if the first reactant is oxygen, hydrogen is supplied by the second supply device.
  • a water supply is provided, from which a cooling medium can be made available. It can be provided that liquid water or cold steam is supplied. It is also possible for liquid water and cold steam or a mixture of liquid water and cold steam to be made available separately from the water supply.
  • the first reaction portion having the first combustion chamber has at least one injection nozzle arranged on the upstream side.
  • the first reactant i.e. hydrogen or oxygen
  • the first combustion chamber is introduced into the first combustion chamber through the injection nozzle.
  • a connection from the first supply device to the injection nozzle is obviously required.
  • the first combustion chamber has at least one injection port on the upstream side on, through which the second reactant, ie oxygen or hydrogen, is introduced into the first combustion chamber.
  • the second reactant ie oxygen or hydrogen
  • a cooling medium is supplied during or after the first combustion.
  • a second reaction section with a second combustion chamber, which adjoins the first transition section, is also required.
  • Downstream of the second combustor is the second transition section of the second reaction section.
  • At least one water inlet is also present on the second combustion chamber and/or on the second transition section, through which a cooling medium can in turn be supplied.
  • At least a third reaction section with a third combustion chamber is required. This follows analogously to the second transition section. Likewise, on the upstream side of the third combustion chamber, there is at least one injection port for repeatedly supplying the second reactant.
  • the third transition section of the third reaction section is located downstream of the third combustion chamber. Furthermore, it is necessary according to the invention that at least one water inlet is also present on the third combustion chamber or on the third transition section, through which a cooling medium can in turn be supplied.
  • Combustion device is provided that one of the two reactants are introduced through the at least one injection nozzle and the other reactant through the injection openings in the combustion chambers of the stepped reaction sections. It is essential here that the first reactant is always present in excess, except for the final combustion in the last combustion chamber. This means that a larger amount of the first reactant that deviates from the stoichiometric amount is deliberately added.
  • the second reactant is introduced into the first combustion chamber through the injection opening and at least 1.5 times the quantity required for stoichiometric combustion is introduced through the injection nozzle.
  • the second reactant in contrast to the first reactant, only an insufficient proportion of the second reactant is introduced into the first combustion chamber for complete combustion.

  • the combustion process is repeated in the further reaction sections.
  • the second reactant is supplied in the amount provided for the respective combustion through the respective injection openings.
  • a cooling medium is supplied again via the water inlets in the further reaction sections, so that a permissible outlet temperature at the outlet of the respective reaction section is not exceeded. Whether it is necessary to feed in the first reactant depends in particular on the remaining amount fed in from the preceding reaction section. If this is already sufficient, no further supply of the first reactant takes place in the corresponding reaction section.
  • the respective supply or its necessity also depends on how high the excess of the first reactant should be in the respective, but not the last, reaction section. At least, if necessary, enough of the first reaction partner is fed in through at least one corresponding injection nozzle so that at least 1.5 times the amount required for stoichiometric combustion is present in the respective (except for the last) combustion chamber.
  • the 1.5-fold amount of the first reactant relative to the second reactant refers to the two components hydrogen and oxygen, with the proportion of water or water vapor still present not being taken into account.
  • the quantity of the first reactant supplied through the injection nozzle and the quantity of the second reactant supplied through the injection openings are fed into the individual reaction sections of the combustion device in such a way that, except for the last reaction section After each combustion in the respective combustion chambers, a relevant portion of the first reactant remains for the respective subsequent reaction section.
  • the basic idea of the invention is the reduction of the combustion temperature through the reduced supply of the second reactant and thus a change in the mixing ratio deviating from the stoichiometry - apart from the combustion in the combustion chamber of the last reaction section.

  • the first reactant is oxygen and the second reactant is hydrogen.
  • the first reactant is hydrogen and the second reactant is oxygen. Accordingly, in a first advantageous procedure, hydrogen is selected as the first reactant, which is present in excess up to the last combustion process. In contrast, the amount of oxygen intended for the combustion taking place there is fed into each combustion chamber.
  • oxygen is selected as the first reactant, which is analogously present in excess up to the last combustion process.
  • the amount of hydrogen intended for the combustion taking place there is fed into each combustion chamber.
  • the combustion device according to the invention with a multi-stage partial combustion both limits the temperatures occurring during combustion and enables optimal control of the combustion without a significant need for a cooling medium, so that the result is a particularly advantageous combustion of hydrogen.
  • the supply of the first reactant and the supply of the second reactant into the first combustion chamber is adjusted in such a way that the combustion chamber contains at least three times the amount of the first reactant required for stoichiometric combustion.
  • the second reactant and, if necessary, the first reactant should be added in such an amount that the combustion chamber contains at least twice the amount of the first reactant required for a stoichiometric ratio.
  • the first reactant required for the entire combustion over the several stages is supplied completely through the at least one injection nozzle into the first combustion chamber.
  • the changing mixing ratio with the increasing vapor is compensated to some extent by the decreasing excess of the first reactant.
  • the entire quantity of the first reactant fed to the combustion device through the injection nozzle and the entire quantity of the first reactant fed to the combustion device through the injection openings supplied amount of the second reactant is dimensioned such that, if possible, a stoichiometric combustion takes place in the last combustion chamber.

  • the cooling medium is supplied in the respective transition sections.
  • Another advantage is that the combustion in the combustion chamber can be better controlled, and the temperature control, in particular the setting of a desired outlet temperature at the outlet of the respective reaction section, is simplified by the appropriate dimensioning of the coolant quantity.
