Definitions

  • the present invention relates to a burner according to the preamble of claim 1.
  • Such burners, their application and installation options are known from EP-A-0193 838.
  • the structure of such a burner arrangement is described in detail, to which reference is expressly made here, so that the description below can be limited to the new details essential to the invention.
  • the burner known from the prior art is also suitable for operation with gas and / or oil, but both alternatives cannot be carried out in the premix mode.
  • the known arrangement works as a diffusion burner, which has disadvantages in terms of pollutant emissions.
  • the known burner arrangement has a plurality of nozzle pipes in the area of the main air flow, through which gas is admixed to the air flow.
  • gas is admixed to the air flow.
  • such an admixing system could also be supplied with oil instead of gas, but because of the completely different volume flows, the nozzles would have to be dimensioned quite differently. Therefore, once installed, the system is only suitable for either premix operation with gas or with oil.
  • the favorable gas feed location before the swirl blading is not particularly suitable for the feed of oil and its fine atomization, since in In this area the air flow velocity is relatively low.
  • the object of the present invention is therefore a development of the known burner arrangement for operation with gas and / or oil without changing the internals. Possibly. the simultaneous use of gas and oil as fuel should also be possible.
  • the goal is in every case the reduction of pollutant emissions, in particular NOx emissions.
  • inlet nozzles for oil should also be present in the main burner system, which allow premixing of the main air flow with oil.
  • Favorable arrangements of the inlet nozzles and design options of the associated oil supply system are contained in claims 2 to 9 and are explained in more detail with reference to the drawing.
  • the feed of inert substances for example steam, water or nitrogen
  • These measures can also be used and are suitable for the arrangement according to the invention.
  • the burner according to the invention which can optionally be used in conjunction with several similar burners, for example in the combustion chamber of a gas turbine system, consists of an inner part, the pilot burner system, and an outer part, the main burner system, which is concentric with it. Both systems are suitable for operation with gas and / or oil in any combination. Natural gas and heating oil are generally used as fuels.
  • the pilot burner system consists of an inner oil feed channel 1 and an inner gas feed channel 2 arranged concentrically around it. This in turn is surrounded by a concentrically arranged inner air (or inert) feed channel 3.
  • a or in this channel can suitable ignition system can be arranged, for which many possible designs are known and the illustration of which has been omitted here.
  • the inner oil supply duct 1 has an oil nozzle 5 at its end, the inner air supply duct 3 has a swirl blading 6 in its end region.
  • the pilot burner system 1, 2, 3, 5, 6 can be operated with oil or gas in a manner known per se.
  • the design of the pilot burner system as a separate premix burner known from EP-A-0193 838 is also suitable for the proposed arrangement and does not impair it.
  • the main burner system consists of an outer air supply ring duct system 4, which is arranged concentrically to the pilot burner system and slants towards it.
  • This air supply ring duct system 4 is also provided with a swirl blading 7. Upstream of the swirl blading there are gas nozzle tubes 10 with a plurality of gas nozzles 11 in the flow cross section of the main air flow L H. These are fed from a gas ring channel 9, which has a main gas supply line 8.
  • the burner additionally has a further oil ring channel 13, which is fed from a main oil supply line 12.
  • This oil ring channel 13 is concentric with the pilot burner system 1, 2, 3, 5, 6, in the area in which it collides with the main burner system 4, 7.
  • a free space which is present there in previous designs can accommodate the oil ring channel 13. It can be formed by a single additional partition.
  • the oil ring channel 13 has holes through the wall to the outer air supply ring channel system 4, which end in the area of the swirl blades 7. These holes are provided with nozzles which generate an oil spray 15 which is directed approximately perpendicular to the main air flow L H.
  • the main air flow L H causes a fine atomization of the injected oil.
  • At least one inlet nozzle 14 is preferably arranged in each space between the blades of the swirl blades 7.
  • the oil supply can be regulated via the oil pressure in the oil ring channel 13.
  • the burner according to the invention enables flexible adaptation to the type of fuel available in each case while minimizing the NO x emission.
  • the burner can work as a premix burner both when operating with gas and when operating with oil and, if necessary, in combinations of both modes of operation, the stability of the flame being ensured by a pilot burner system.
