Definitions

  • the invention relates to a boiler system according to the preamble of claim 1.
  • EP-A-0 266 857 shows a boiler system with two combustion chambers, whereby an aperture is arranged in the second combustion chamber. It is used for Increase in turbulence and thus heat exchange.
  • the invention as set out in the claims is characterized, the task is based on a boiler system to propose precautions to avoid excessive cooling of the reacted gases, i.e. of the recirculated flue gases prevented.
  • the combustion chamber is divided into two parts, in particular the front part of the combustion chamber relevant to the effect becomes.
  • the one according to the invention Measure in that the effect is achieved that an inner Return flow zone and outer return flow zones are each locally defined to one another can arise, which results in a clear separation of the two.
  • the main advantage of the invention is that the flow in the Combustion chamber center is accelerated, which leads to a shortening of the inner Backflow zone leads, i.e. this inner backflow zone is limited downstream. This means that hotter flue gases are now on the burner axis arise, and so too much cooling of those formed there reacted Gases is prevented. These gases, which are now at a higher temperature level then flow as recirculated flue gases over the as separated acting and locally defined with respect to the inner backflow zone Backflow zones to an injector system belonging to the burner.
  • FIG. 1 shows a boiler system 100 belonging to the prior art, as is customary is used for heating systems.
  • This boiler system 100 exists essentially from a combustion chamber formed from a flame tube 101 102, which is surrounded by a heat-resistant partition 105.
  • the boiler system is operated here by a premix burner, the description of which 3 and 4 can be seen in more detail.
  • the operation of this boiler system can be but do not do it alone with this burner; other types of burners each with flame stabilization can also be used.
  • the Fig. 1 mainly wants the aforementioned almost cylindrical elongated Show backflow zone 24a, which leads to the disadvantages mentioned there, and which are canceled by the proposal according to FIG. 2.
  • Fig. 2 shows the subdivision of the combustion chamber by an acting as an aperture annular disc 103, the steps 104 a boundary of the inner backflow zone 24 effect.
  • This inner backflow zone 24 is thus in the direction of flow limited within the front part 17 of the combustion chamber what excessive cooling of the reacted gases prevented.
  • the second part 102a of the combustion chamber, downstream of the aperture 103, serves as an exhaust zone.
  • the current itself becomes within the first part 17 of the combustion chamber in the center of the combustion chamber accelerates, which then results in a compact and shortened inner backflow zone 24 leads, as can be seen quite clearly from FIG. 2.
  • By hotter Flue gases on the burner axis leading to the burner will be a better one Flame stabilization reached.
  • step 104 of the annular disk 103 i.e. the degree of cross-sectional reduction triggered by such means resp. the degree of reduction in flow passage.
  • FIG. 3 shows a premix burner in perspective.
  • FIG. 4 shows a premix burner in perspective.

  • a nozzle 11 for preferably atomizing a liquid Fuel 12 housed, such that their injection approximately with the narrowest cross-section of the cone cavity formed by the partial bodies 1, 2 8 coincides.
  • This nozzle 11 depends on the specified parameters of the respective premix burner.
  • the fuel 12 injected through the nozzle 11 can, if necessary, with a recirculated exhaust gas are enriched; then it is also possible through the Nozzle 11 to accomplish the complementary injection of a quantity of water.
  • the premix burner can be purely conical, i.e. without a cylindrical one Initial parts 9, 10 may be formed.

  • These fuel lines 13, 14 are preferably at the latest placed at the end of the tangential inflow, before entering the cone cavity 8, this to ensure an optimal air / fuel mixture.
  • the premix burner On the combustion chamber side, the premix burner has an anchorage for the partial bodies 1, 2 serving front panel 18 with a number of holes 19 through which if necessary, a mixed or cooling air 20 the front part of the combustion chamber 17th or whose wall is fed.
  • the premix burner is used solely by means of a liquid Operated fuel 12, this is done via the central nozzle 11, wherein this fuel 12 then enters the cone cavity 8 at an acute angle or is injected into the combustion chamber 17.
  • the nozzle 11 thus forms a tapered fuel profile 23 rotating from the tangentially flowing Combustion air 7 is enclosed. In the axial direction, the concentration of the injected fuel 12 continuously through the incoming combustion air 7 broken down into an optimal mixture.
  • a backflow zone 24 (vortex breakdown) also forms there with one opposite the flame front 25 acting there stabilizing effect, in which Meaning that the backflow zone 24 functions as a disembodied flame holder takes over.
  • the optimal fuel concentration across the cross section is only in the area the vortex runout, that is, in the area of the backflow zone 24.
  • a stable flame front 25 is then created at this point Effect results from the swirl number in in the cone cavity 8 Flow direction along the cone axis. A backlash of the flame into that This prevents the interior of the premix burner.
  • the design of the premix burner is suitable furthermore excellent, the flow opening of the tangential air inlet ducts 5, 6 to change as required, which means without changing the overall length of the premix burner a relatively large operational bandwidth can be covered.

  • Premix burners of the type described here are also those which are to be achieved a swirl flow from a cylindrical or quasi-cylindrical tube go out, the inflow of combustion air into the interior of the pipe tangential air inlet channels is also accomplished, and inside of the tube a conical body with decreasing in the flow direction Cross section is arranged, which is also critical with this configuration Swirl number at the output of the burner can be achieved.
  • FIG. 4 shows the same premix burner according to FIG. 3, but from a different one Perspective and in a simplified representation.

Upstream of each feed channel 27, 28, the serves as a tangential inflow into the interior 8 of the premix burner the fresh air 29 evenly over the entire length of the premix burner Perforated plates 31, 32 distributed. In the direction of flow to the tangential inlet channels 5, 6 these perforated plates 31, 32 are perforated.
  • the perforations fulfill the function individual injector nozzles 31a, 32a, which have a suction effect compared to the surrounding flue gas 30 exert such that each of these injector nozzle 31a, 32a each only sucks a certain proportion of flue gas 30, whereupon over the entire axial length of the perforated plates 31, 32, which corresponds to the burner length, a uniform flue gas admixture takes place.
  • This configuration causes that at the point of contact of the two media, i.e. the fresh air 29 and the flue gas 30, an intimate mixing takes place, so that the up to the tangential air inlet slots 5, 6 reaching flow length of the supply channels 27, 28 can be minimized for the mixture formation.
