Abstract

For a coupling of the gas turbine process with the allothermal gasification, in particular by means of water vapor, solid fuels is to avoid heat pipes (26), which must be operated with hazardous liquid alkali metals, a second combustion chamber (25) except the combustion chamber (6) of the steam turbine provided, the heat can be provided at a lower temperature level and thus with non-hazardous means the other processes.

Description

  • I. Field of application
  • The invention relates to a solids-fired gas turbine.
  • II. Technical background
  • In thermodynamics, numerous processes for the conversion of chemically bound energy into mechanical or electrical energy are known. One differentiates thereby processes, with which each fuel can be used, of those, which are reserved for only a few (nobler) fuels. The processes, which are reserved for only a few fuels, usually have a significantly higher process efficiency, so that there is always a desire to make these processes accessible even to less noble fuels.
  • For example, the Clausius-Rankine process (steam-power process) belongs to the category where combustion in a steam generator can use any fuel, while a joule process (gas turbine process) only uses liquid or gaseous fuels is. Gas turbines are work machines in which cold air is compressed in a compressor, then heated in a combustion chamber by combustion of combustibles and finally expanded in a turbine. Since the relaxation of the gas takes place at a much higher temperature than the compression, mechanical work is released in this process. The use of solid fuels always fails due to the problem that the combustion of solid always produces ash particles, which are present in the flue gas. Gas turbines do not tolerate dust-like particles. There are therefore numerous attempts to remove the dust particles before entering the gas turbine. Ultimately, however, all these methods lead to a significant loss of efficiency of the Joule process.
  • In the patent US 4,212,652 For the first time, it is possible to use Joule process with the help of an allothermal gasification of carbonaceous feedstocks with steam, which achieves the same order of magnitude of efficiency with solid (non-noble) fuels as with gaseous (noble) fuels. However, the process has so far not found commercial uses, which is probably due to problems in providing the surfaces or temperature differences required for heat transfer.
  • A further development is the registration DE 10 2004 033 348 A1 in which the heat input is to take place via heat pipes.
  • Here, the heat required for the allothermal gasification is decoupled from the combustion chamber of a gas turbine and coupled by means of heat pipe systems in an allothermic gasification chamber. The synthesis gas produced in the allothermal gasifier is fed to the gas turbine after gas purification of the combustion chamber. The heat required for the heating of the gasification chamber is contained according to the 1st law of thermodynamics as additional heat in the synthesis gas and is thus performed in a short cycle back to the gasifier. The second part of the heat contained in the synthesis gas corresponds to the chemically bound energy of the fuel and is present in the synthesis gas predominantly as chemically bound heat, to a lesser extent as latent or sensible heat. This heat is used in the gas turbine completely for heating the compressed air, so that the process proceeds with the same efficiency as the use of precious energy sources such as natural gas.
  • However, the process is designed very complex due to the extraction of heat from the combustion chamber of the gas turbine and the coupling in an allothermal carburetor. The heat transfer from the combustion chamber into the carburettor takes place by means of heat pipes, in which liquid alkali metals in metallic form as heat transfer medium are required at the required temperature range. These media always carry a latent risk of leakage, leading to highly exothermic reactions with the formation of highly corrosive alkali oxides or alkali hydroxides.
  • III. Presentation of the invention
  • a) Technical task
  • It is therefore the object of the invention to maintain the efficiency potentials of the novel process and at the same time to minimize or completely avoid the dangers of the alkali metals.
  • b) Solution of the task
  • This object is solved by the features of claims 1 and 9. Advantageous embodiments will be apparent from the dependent claims.
  • By in a second, separate from the combustion chamber of the gas turbine combustion chamber compressed fresh air and a fuel burned together, usually burned under pressure, and the heat from this combustion of the second combustion chamber is provided to the allothermal gasification process is due to the lower temperature levels of combustion in the second combustion chamber compared to Temperature levels in the combustion chamber of the gas turbine, even with the use of heat pipes, the risk of leakage of liquid alkali metals not given because they are not needed because of the lower temperature levels but other, safer heat transfer medium can be used for this purpose.
  • In this case, the fresh air for this second combustion chamber can be treated separately, so compressed, and also be relaxed again afterwards. The fuel used is preferably part of the product gas generated in the gasification chamber, but any other fuel may be used.
  • Preferably, however, in a first embodiment according to the invention, a first partial flow of compressed for the gas turbine process fresh air before the combustion chamber of the gas turbine (under certain circumstances, only after this combustion chamber) withdrawn and fed to the second combustion chamber. This saves the effort of a separate preparation.
  • This partial flow of the compressed fresh air can be additionally recompressed prior to introduction into the second combustion chamber to compensate for pressure losses, which is preferably done by means of a jet pump, which can be operated for example by means of a portion of the steam, anyway for introducing the required heat and / or fluidizing the fluidized bed in the gasification chamber is required for the solid fuel.
  • The combustion heat generated in the second combustion chamber can be used for the process in different ways:
    The one solution is that this second combustion chamber is a separate combustion chamber, which is thus used exclusively for the combustion of the air introduced there with the fuel introduced there. This has the advantage that the processes in this separate combustion chamber can be controlled very accurately independently of other processes.
  • From this second, separate combustion chamber on the one hand heat can now be coupled and fed to the gasification chamber using heat pipes, for which preferably the second combustion chamber should not be located too far away from the gasification chamber, but as close as possible.
  • Furthermore, the combustion gases escaping from this second combustion chamber contain a great deal of heat. These fuel gases are therefore returned to the gas turbine process by being preferably introduced from the combustion chamber of the gas turbine in the expander as the fuel gases. Another possibility is to first mix the combustion gases from the second combustion chamber with a portion of the product gas and to supply them to the first combustion chamber of the gas turbine process. Also, a supply in the gasification chamber as a fluidizing agent - or mixed with product gas as a fuel - is conceivable.
  • Another solution is that the gasification chamber itself is used as the second combustion chamber.
  • Then, the compressed fresh air for the second combustion chamber, so for example, the branched off from the compressed fresh air for the gas turbine process substream, the gasification chamber, in particular the local fluidized bed, fed and there with a part of the introduced there solid fuel and / or with a part of the in the Gasification chamber recirculated product gas burned.
  • The advantage is that the structural complexity is reduced because no separate combustion chamber is needed. The further advantage is that the heat produced during the combustion is already in the gasification chamber, and does not have to be transported there first.
  • The disadvantage is that this combustion takes place within the gasification chamber and can not be controlled and regulated separately from it.
  • A heat transfer is only necessary within the gasification chamber, but is there usually fulfilled by the existing fluidized bed as a heat transfer medium:
    Thus, the circulating fluidized bed may be exothermic in an area where combustion primarily occurs, and endothermic in another area where primarily the solid fuel gasification takes place. However, a heat exchange between these two areas is quasi automatically given by the circulation of the fluidized bed.
  • The treatment of the vapor required for the gasification chamber as a hybridization agent can also be usefully integrated into the overall process:
    The exhaust gases escaping the expander, such as the turbine, of the gas turbine process still contain a lot of heat, which can be used. On the one hand, this can be used to heat the compressed air for the gas turbine process, which increases its efficiency. On the other hand, this can cause the vaporization of the water and / or heating of the already generated steam for the gasification process.
  • Since these two heating processes occur at different temperature levels, it makes sense to use the exhaust gases from the expander first for heating the compressed air and only then at the then slightly lower temperature level for evaporating the water or heating the already generated steam.
  • To carry out the method, therefore, a device is needed which comprises, in addition to a gas turbine with compressor, combustion chamber and expander, a gasification chamber for gasifying a solid fuel, the latter preferably being operated by means of a fluidized bed, and the raw gas produced there being preferably combined via a gas scrubber. Further, in addition to the combustion chamber of the gas turbine, a second combustion chamber is needed, which may be present separately or for which the gasification chamber can be used.
  • In the former case, a heat-conductive connection is preferably necessary in the form of heat pipes between this separate second combustion chamber and the gasification chamber.
  • Preferably, a heat exchanger is also provided for heating the compressed fresh air for the gas turbine, and a heat exchanger for evaporating water for generating the fluidizing steam, which are preferably both operated with the exhaust gases of the expander from the gas turbine.
  • c) embodiments
  • Embodiments according to the invention are described in more detail below by way of example. Show it:
  • 1 a first embodiment according to the invention, and
  • 2 A second embodiment according to the invention.
  • In the 1 is the gasification chamber on the top right 27 represented in the lower region is a circulating fluidized bed 43 located by water vapor supplied from below 21 is fluidized. The one about the fuel supply 28 in the gasification chamber 27 fed solid fuel is in the gasification chamber 27 - As a rule, under pressure - largely gasified, possibly also burned to a part, in which case the resulting heat of combustion benefits the gasification of the other solid fuel, and thus the generation of the raw gas 29 which after cleaning in a gas scrubber 30 as a product gas 31 is available.
  • Since this gasification process is allothermic, except for the solid fuel, even if this partially in the gasification chamber 27 Burns even more heat are supplied, resulting in the fluidizing steam 21 done and partly via heatpipes 26 ,
  • In the middle area of the 1 is the one from the first combustion chamber 6 and the turbine acting as an expander 10 existing gas turbine shown.
  • In the combustion chamber 6 the gas turbine becomes a diverted partial flow 7 of the product gas 31 together with in a compressor 1 compressed air 2 additionally in a heat exchanger 12 is heated, burned. The fuel gases 8th the second combustion chamber 25 become the turbine 9 fed.
  • A partial flow 4 the compressed and warmed up fresh air 3 is in a steel pump 23 recompressed and this recompressed fresh air 24 a second separate combustion chamber 25 fed, in which a partial flow 32 of the product gas of the 31 together with this recompressed fresh air 24 is burned. The surplus 34 of the product gas 31 is then available for further use. The resulting heat of combustion is partly on the heatpipes 26 the fluidized bed 43 in the gasification chamber 27 fed, and partly in the form of the separate second combustion chamber 25 discharged fuel gases 35 the turbine 10 fed.
  • The fluidizing the fluidized bed 43 in the gasification chamber 27 needed steam 21 is by evaporation of water in the heat exchanger 13 generated, and in a partial flow 21 directly to the fluidized bed 43 fed in another sub-stream 22 initially to operate the steel pump 23 used.
  • The from the compressor 1 compressed air 2 is in a heat exchanger 12 further warmed up, with both the heat exchanger 12 as well as the heat exchanger 13 by means of heat from exhaust gases of the turbine 10 to be operated by the exit 11 the turbine 10 first to the heat exchanger 12 and then through the heat exchanger 13 be guided before they are released into the area.
  • The solution according to the 2 is different from the one of 1 in that there is no separate second combustion chamber here 25 is present, but the front of the combustion chamber 6 the gas turbine branched partial flow 4 the compressed and heated air 3 - Re-compressed to compensate for pressure losses by means of the jet pump 23 - the fluidized bed 43 in the gasification chamber 27 is supplied, which acts in this case as a second combustion chamber.
  • The compressed air 24 reacts there with the solid fuel and thereby generates heat, the gasification process in the gasification chamber 27 accelerates and / or reacts with the fluidized bed 43 the gasification chamber 27 recirculated product gas 41 or raw gas 29 if such a recirculation at the gasification chamber 27 is provided.
  • This causes an increased yield of product gas 31 which, as in the first embodiment in a partial flow 7 the first combustion chamber 6 the gas turbine is supplied and the rest - optionally after branching of the recirculated product gas 41 - as surplus 34 is available for further use.
