Definitions
- the invention relates to a premix burner for gaseous Fuels, with an ionization electrode attached to a Control device is connected.
- the burner works according to the so-called SCOT process, in which the ionization signal supplied by the ionization electrode is electronically processed to make a statement about the flame temperature and thus about the air ratio to deliver.
- the process aims to keep the air ratio constant to keep and thus a low-pollution combustion of gases with changing composition.
- the quality of the regulation depends on the straightness the course of the ionization signal over the burner output from.
- the invention has for its object the burner control to improve that you have an ionization signal is supplied, whose linearity over the burner output is increased.
- the invention is based on the knowledge that the Quality of the ionization signal from the area load of the Brenners depends. The lower the wing load, deste the weaker the ionization signal and the earlier its drop begins with a decrease in burner output. On the other hand the general technical trend is heading in the direction low wing loads in order to minimize pollutant emissions to achieve.
- the invention creates a local increase in wing loading and, in many cases, enables use of the SCOT process by appropriate improvement the quality of the ionization signal. Under all circumstances the usable power range of the burner is down expanded. The increase in wing loading is local limited and therefore leads to none, in the worst case only to an insignificant influence on the emission values.
- the premix burner is one, who works with a flame holder or mixture distributor, which has a plurality of mixture outlet openings has, it is proposed in a development of the invention the mixture passage area of the flame holder in the area to enlarge the ionization electrode. The additional The effort for a pilot burner is therefore replaced by a minor constructive redesign of the flame holder.
- the mixture passage openings in the area the ionization electrode can be enlarged. More advantageous for a stable burner operation it can be in critical area the density of the mixture passage openings to increase.
- 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 inside. 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.
