  • the use of a closed or quasi-closed circuit with the addition of pure oxygen also prevents atmospheric nitrogen from getting into the flame, as a result of which no or only minimal nitrogen oxides are generated.
  • the setting of optimal combustion conditions with regard to flame stability, hot gas temperature and degree of dissociation, for example with regard to the formation of carbon monoxide (CO) is often a problem.
  • the invention has for its object to ensure optimal combustion conditions in methods for operating a power plant of the type mentioned.
  • the essence of the invention is therefore that the combustion of the fuel mass flow takes place in an artificial air that can be adjusted by means of regulating elements.
  • Another advantage of the adjustable proportions of artificial air with regard to 0 2 -, C0 2 - and H 2 0 is that the CO content and the proportion of unburned hydrocarbons (UHC) do not exceed certain limit values.
  • the adjustment of the artificial air takes place via regulating devices and regulators, the regulation taking place depending on the fuel mass flow and / or one or more characteristic quantities of the hot gas.
  • the criterion for stable combustion can be, for example, the avoidance of pulsations during combustion in the combustion chamber.
  • FIG. 1 shows a circuit of a gas turbine process with a closed circuit.

  • the artificial air 17 generated in the mixer 9 is fed to the combustion chamber 2 and burned there with a fuel mass flow 14, for example natural gas with the main component methane, which is supplied via a control element 13.
  • the hot gas 11 released in the process consisting essentially of the components C0 2 and H 2 0 and, if appropriate, with the inert gases supplied with the oxygen or the fuel, is fed to the turbine 3 and expanded there with the release of work.
  • the turbine outlet stream is fed to the cooler and / or waste heat processor 4 via a line 16 and cooled there.
  • the water condensed out by the cooling is separated off via the water separator 5.
  • the remaining circulating medium 23 from the majority of C0 2 is then fed back to the compressor 1.
  • the regulation of the fuel mass flow 14 and the oxygen mass flow 8, which is used with the partial flow 7 of the circulating medium 23 to generate the artificial air 17, is carried out via a regulator 21, which regulator is connected to the control element 13 and thus to the fuel mass flow 14 and to the control element 15 and thus acts on the oxygen mass flow 8.

  • the optimal mixture of the artificial air 17 is determined by an analysis of the hot gas 11, for example downstream of the turbine 3 in the line 16.
  • the control member 12 is controlled by a controller 22 and thus the part of the circulating medium required for mixing the optimal artificial air 17 via the control member 12, ie the inflow of C0 2 or C0 2 / H 2 0, is branched off.
  • the C0 2 or C0 2 / H 2 0 inflow 7 to the oxygen stream 8 is also influenced by a temperature limiting signal 18 of the actual flame temperature. The latter may not exceed a design-related maximum.
  • the largely closed C0 2 gas turbine cycle according to FIG. 1 thus has internal combustion of a hydrocarbon, for example a natural gas with the main component CH 4 , in an "artificial air" prepared from 0 2 , C0 2 and possibly H 2 0 components C0 2 and H 2 0 resulting from the combustion and any inert gases introduced with the oxygen or natural gas are continuously removed, so that a circuit 23 with a largely constant composition of the working medium is maintained.

Abstract

L'invention concerne un procédé d'exploitation d'une centrale électrique comportant un circuit fermé ou quasi-fermé. Ladite centrale est essentiellement composée d'au moins une unité de compression (1) ou d'une pompe, d'au moins une chambre de combustion (2), d'au moins une turbine (3) et d'au moins une source froide (4). Dans la chambre de combustion (2), un flux massique de combustible (14) réagit avec au moins un flux d'oxygène (8). Les produits de combustion excédentaires ainsi produits (CO2, H2O) sont prélevés du circuit dans une zone adaptée (5, 6). La combustion du flux massique de combustible (14) est effectuée dans une atmosphère artificielle pouvant être obtenue au moyens d'organes de régulation (12, 13, 15).
