Definitions
- the invention relates to a premix burner for gaseous fuels, with a mixture distributor, which has a plurality of mixture passage openings has and with an ionization electrode, which is connected to a control device connected.
- the burner works according to the so-called SCOT process, in which the The ionization signal supplied by the ionization electrode is electronically processed is to make a statement about the flame temperature and thus about to supply the air ratio.
- the process aims to keep the air ratio constant hold and thus a low-pollutant combustion of gases with changing Allow composition.
- the goodness depends on Regulation of the straightness of the course of the ionization signal over the Burner output.
- the invention has for its object the burner control in this regard to improve that it gets an ionization signal whose linearity is increased above the burner output.
- the premix burner mentioned at the outset is according to the invention characterized in that the wing loading of the Premix burner in the area of the ionization electrode is increased by the Ionization electrode is assigned to a pilot burner or by the Mixture passage area of the mixture distributor in the area of the Ionization electrode is enlarged.
- the invention is based on the knowledge that the quality of the ionization signal depends on the burner's surface load. The lower the area load, the weaker the ionization signal and the earlier the waste begins to drop as the burner output drops. on the other hand the general technical trend is towards low wing loads, in order to achieve the lowest possible pollutant emissions.
- the invention creates a local increase in wing loading and enables in many cases, the use of the SCOT process only by appropriate Improvement of the quality of the ionization signal. Among all Under certain circumstances, the usable output range of the burner will decrease extended. The increase in wing loading is locally limited and leads therefore to none, in the worst case only to an insignificant influence the emission values.
- the premix burner 1 according to FIG. 1 is connected to an air line 2 and connected to a gas line 3.
- a blower 4 works while in the gas line a pressure regulator 5 is arranged.
- the pressure regulator 5 works depending on additional electronics 6, which in turn connected to a customer-specific boiler electronics 7 is. The latter also controls the blower 4.
- An ionization electrode 8 indicated as a line delivers their signal to the additional electronics 6, in which this signal is processed so that it is the air ratio of the premix burner 1 represents.
- the ionization electrode 8 is in the area of a pilot burner 9 arranged, both with the air line 2 as is also connected to the gas line 3 and therefore a The mixture burns, as does the burner head 1 ' becomes.
- the pilot burner 9 is at a higher wing loading as the burner head 1 '.
- the additional electronics 6 thus generates a higher ionization signal Quality.
- this signal is plotted against the boiler output, in comparison to the signal that results when the ionization electrode in the region of burner head 1 'working with a low surface load, is arranged.
- the ionization signal then clearly drops decreases significantly with decreasing burner output, including the The quality of the scheme suffers, with the result that the air ratio of the premix burner 1 does not change when the gas changes can be kept more constant.
- FIG. 3 shows a mixture distributor 10 of a premix burner in the form of a burner plate with a plurality is provided by mixture passage openings 11. About that The largest surface area of the burner plate is the density of the Mixture passage openings 11 selected so that the burner works with low wing loading and therefore cheap Emission values achieved.
- the ionization electrode 8 is on the left edge of the burner plate arranged and extends in their area into it. As shown, the density of the mixture passage openings is here 11 increased. The mixture passage area is so enlarged that the burner in this area works with increased wing loading. The effect corresponds that of the pilot burner 9 according to FIG. 1. Since the increase the area load is locally limited, the emission values hardly affected.
- the Pilot burner can be coupled directly to the burner head.
- the type of control electronics is arbitrary, but under the Prerequisite that from the ionization current of the electrode a signal representing the air ratio can be derived can.
