Definitions

  • the invention relates to a burner for the Operation of a heat generator according to the generic term of claim 1.
  • a burner has become known from EP-0 780 629 A2, the upstream side from a swirl generator exists, the flow formed herein is seamlessly transferred into a mixing section.
  • the outflow side of these transition channels has the Mixing section a number of filming holes, which is an increase in flow velocity ensure along the pipe wall. Subsequently follows a combustion chamber, the transition between the mixing section and the combustion chamber a cross-sectional jump is formed in the Level a backflow zone or backflow bubble forms.
  • the swirl strength in the swirl generator is made chosen so that the vertebra does not burst within the mixing section, but further downstream takes place, as explained above, in the area of the cross-sectional jump.
  • the swirl generator fulfills that here Function of a premix section. This consists of at least two hollow, conical, in the direction of flow nested partial bodies, whereby the respective axes of longitudinal symmetry of the individual Partial body run mutually. Form thereby the neighboring walls of the partial body in their Longitudinal extension of tangential inflow channels for a combustion air flow, being in from the partial bodies formed interior at least one fuel nozzle acts.
  • the burner changes into a diffusion mode, which then inevitably leads to high NO x emissions.
  • the burner may overheat or even burn parts of it.
  • the fuel is therefore injected as far downstream as possible so that the flame cannot strike back upstream.
  • the fuel is diluted with water vapor or nitrogen, but in both cases the efficiency is reduced.
  • the invention seeks to remedy this.
  • the Invention as characterized in the claims is the task of a burner propose precautions at the beginning, which is a good mix when using a low calorie Fuel, with minimized pollutant emissions and maximized efficiency guarantee.
  • the swirl generator receives for this purpose in addition to the air intake ducts, a second independent one Fuel guide, preferably designed as a channel, through which the low calorific fuel is introduced. This will then be adequately admixed to the combustion air flow, in such a way that there is a partial mix of the two media comes before this in the wider interior of the Swirl generator flow.
  • Another advantage of the invention is therein see that the fuel is injected isokinetically can, with which high turbulence is injected between the Fuel and the combustion air flow preventing the flame from kicking back is sustainably suppressed.

  • the two streams namely the combustion air 115 and the gaseous Fuel 117, will be until their first mixing. before the inflow of the same into the Interior 118 happens, managed independently.
  • the Fuel 117 becomes the combustion air 115 .mu.m a stretch upstream of the tangential transition Inflow channels 101b-104b into the interior 118 mixed. This ensures that the both media until entering the interior 118 have already pre-mixed. This can be done constructively by using the fuel channels 121-124 the respective body 101-104 as an independent Guided tours are put on.
  • the flow openings of the two media 115, 117 to the level of their Mixing is designed so that the flow allow approximately the same mass flow, which is always necessary when the burner is connected an LBTU or MBTU gas is operated.
  • present the gaseous fuel 117 flows out of the gas-carrying channels 121-124, as already mentioned, via the inflow slots 131 on the inside of the combustion air flow 115.

  • the mixing section 220 largely fulfills the task that downstream of the swirl generator 100 a defined route is provided, in which a perfect premixing of different fuelskind can be achieved.
  • This mixing section so superficially the mixing tube 20 further enables a lossless flow, so that too in active connection with the transition geometry initially no backflow zone or backflow bubble can form, thus over the length of the mixing section 220 influence on the quality of the mixture for all types of fuel can be exercised.
