Definitions

  • the invention relates to a method for the combustion of gaseous, liquid as well as medium or low calorific fuels in one burner a swirl generator. Furthermore, the invention relates to a burner for Execution of the procedure.
  • DE 195 47 913 A1 describes a generic burner for a heat generator 1, which provides a swirl generator 100 according to FIG. 1, into the axially liquid fuel through a fuel nozzle 103 in the shape of a cone Liquid fuel jet is injected. Tangential and angular to that Liquid fuel jets become combustion air flows between the swirl shells of the swirl generator introduced into the swirl generator, via the corresponding outlet nozzle openings 117 are preferably mixed with gaseous fuel can.
  • the nozzle openings 117 are mainly used for the injection of natural gas, that is, fuel with a high calorific value, which is typically 46 MJ / kg, used.
  • a dual burner will expressly refer to the above-mentioned German published specification referred.
  • Burner systems for a heat generator are preferred for gas turbine operation designed.
  • in addition to natural gas and heating oil, which are used as fuels for Dual burners are used, also preferably medium or low calorific To use fuels (Mbtu or LBtu fuels) that are as it were conventional Fuels should be burned with low emissions.
  • Mbtu resp. LBtu fuels for example as gases from coal or heavy oil gasification come from, have large amounts of hydrogen and carbon monoxide, the The calorific value of MBtu fuels is only about a third - about 15 MJ / kg - of which of natural gas.
  • the invention is based on the idea of using gaseous fuels, for example Natural gas, liquid fuels such as petroleum, as well as medium or low calorific Fuels, so-called Mbtu resp. LBtu fuels in one burner burn together with a swirl generator by the latter Fuel is injected axially and / or coaxially into the burner or swirl generator. These fuels are preferably injected into the interior of the swirl generator near the liquid fuel injector that is injected in State within the swirl generator or burner the shape of a conical Liquid fuel column. This ensures that in addition to the finely atomized liquid fuel inside the swirl generator injected medium or low calorific fuels sufficiently well this is mixed.
  • gaseous fuels for example Natural gas, liquid fuels such as petroleum, as well as medium or low calorific Fuels, so-called Mbtu resp. LBtu fuels in one burner burn together with a swirl generator by the latter Fuel is injected axially and / or coaxially into the burner or swirl generator.
  • the feed of medium or low calorific fuels upstream in the area of the liquid fuel injector also leads to a good mixing with the injected fuels and the combustion air flow injected into the swirl generator.
  • the long mixing section leads to premix combustion, which has comparable good NO x emission values that can be achieved with natural gas premix combustion.
  • the burner according to the invention which is used to carry out the invention Method is designed as an extension to that described in the above German published patent application DE 195 47 913 A1 described dual burner view and points in addition to the fuel systems according to the invention for natural gas and liquid fuel, a third fuel system for feeding a medium or low calorie fuel in the swirl generator. So it ends preferably near the area of the central injector through which liquid fuel is injected into the interior of the swirl generator through the swirl shells of the swirl generator, through which medium or low calorie Fuel is injected into the interior of the swirl generator.
  • the injection of the middle resp. low-calorific fuel takes place axially and / or coaxially with the injection of the liquid fuel or to the axis of symmetry of the swirl generator.
  • the burner shown in Fig. 1 consists of a swirl generator 1 and one Mixing section 2, which adjoins the swirl generator 1 in the flow direction.
  • a conical structure that is tangential several times from a tangentially flowing combustion air flow 3 (see Fig. 2) is applied.
  • Shape and shape of the swirl generator 1 and by the shape of the swirl generator flow kinetics is extensively in the German Offenlegungsschrift DE 195 47 913 A1 with reference to FIGS. 1 to 5 to which express reference is made here.
  • the formation of the swirl generator 1 adjacent mixing section 2 which consists of a transition piece 21 with transition channels 22 and a directly adjacent transition tube 23 is.
  • the mention of these burner components is only for the complete Representation of the burner unit for feeding in the combustion process required fuels.
  • an injection nozzle 4 for the introduction of liquid fuel into the interior of the Swirl generator 1 is provided.
  • Feed lines 5 are coaxial around the injection nozzle 4 the supply of medium-calorific fuel is provided (see arrow representations), which penetrate the swirl generator shells 6, 7.
  • Via appropriate injection nozzles 8 also arrives at the air flow which forms inside the swirl generator 1 (not shown in the figure) finely divided medium calorific fuel axially or coaxially into the swirl generator and mixes with it.
  • supply channels 9 are provided for the gaseous fuel tangentially from the outside together with the combustion air flow into the swirl generator is fed (see Fig. 2).
  • the additional coaxial feed compared to the prior art medium calorific fuel leads to an increase in the axial component of the Flow that after passage through the transition piece 21, in the preferably the transition channels 22 are introduced, and after passing through the mixing tube 23 leads to the so-called "swirl breakdown” (backflow bubble), which occurs at known dual burners in the area of the combustion chamber 10 in the immediate vicinity the mixing tube 23 forms, is literally blown away.
  • a highly efficient feeding of the medium-calorific fuel is preferably carried out by coaxially introduced into the twister cups 6, 6 ', 7, 7' Fuel nozzle openings 8.
  • Medium-calorific fuel is injected via one or more nozzles per swirl suction cup.
  • Fig. 2 shows a cross section through a swirl generator designed according to the invention 1.
  • the liquid fuel nozzle 4 is provided to the angularly several swirl generator shells 6, 6 ', 7, 7' are arranged.
  • Tangential Combustion air 3 is generated between the adjacent swirl generator shells introduced tangentially into the interior of the swirl generator 1, with the help of separate Feed lines 9 with corresponding inlet nozzles is mixed with natural gas.
  • the Swirl generator shells 6, 6 ', 7, 7' are each with one in the example shown Fuel injection for medium-calorific fuel penetrated.
