Definitions
- the invention relates to an oil burner with an oil atomization device, a combustion air supply coaxially surrounding this, which opens into an aperture, and with a mixing tube open at both ends for fuel, combustion air and exhaust gas, which is arranged downstream of the aperture in a combustion chamber, wherein Exhaust gas coming directly from the combustion chamber is sucked around the outside of the mixing tube and into a first, upstream section thereof.
- Oil burners with recirculation of hot exhaust gas that comes directly from the combustion chamber at the beginning of the combustion chamber are known as blue burners or gasification oil burners.
- An oil burner with the features mentioned in the introductory part of claim 1 is known from DE-4-27 00 671. This oil burner has the advantage of particularly soot-free and complete combustion with good thermal efficiency. However, they only achieve these goals within a relatively narrow performance range.
- the invention has for its object to improve an oil burner of the type mentioned while maintaining its advantages with regard to the smallest possible emission of pollutants in an extended performance range.
- both the combustion air supply surrounding the oil atomization device and a downstream, second section of the mixing tube, which is expanded compared to the first section thereof, for supplying a mixture from the Exhaust gas and combustion air removed from the boiler are connected to a line for supplying combustion air and a line for supplying cooled exhaust gas via a mixing device, the line for supplying the mixture of exhaust gas and combustion air opening into the mixing tube in the region of its expansion from the outside.
- an oil atomization device 1 arranged in the longitudinal axis of the oil burner is coaxially surrounded by a combustion air supply which has an inner region 2 and an outer region 16.
- a combustion air supply which has an inner region 2 and an outer region 16.
- an aperture 3 is arranged at the end of the inner area 2 of the combustion air supply.
- the aperture 3 is followed by a mixing tube 4 which is coaxial with the oil burner and is open at both ends.
- the mixing tube 4 has a first section 5 which is widened with respect to the diaphragm opening 3 and a second section 6 which is widened with respect to the first section 5.
- the extension 7 of the mixing tube 4 is designed as a step and is located approximately in the middle of the longitudinal extension of the mixing tube 4.
- the mixing tube 4 is arranged in a combustion chamber 8, which has a first section 9 which extends approximately to the extension 7 of the mixing tube 4 and has a second section 10, which connects with its opening 11 to a boiler, not shown in FIG. 1.
- the first section 9 of the combustion chamber 8 has a radially outer jacket 12, which serves as a line for the supply of a mixture of exhaust gas and combustion air, and an annular space 13 adjoining it on the inside.
- the annular space 13 connects the second section 10 of the combustion chamber 8 to the inlet opening of the mixing tube 4. Due to the injector action of the gas mixture emerging from the orifice 3, hot exhaust gas is converted from the second section 10 of the combustion chamber 8 through the axially parallel lines 18 and the annular space 13 around the mixing tube 4 sucked into this outside.
- the combustion air supply with its areas 2 and 16, which surrounds the oil atomization device 1, is acted upon by a mixture of cooled exhaust gas and combustion air removed from the boiler.
- the end of the outer region 16 of the combustion air supply is connected to the outer jacket 12 of the first section 9 of the combustion chamber 8 via an annular aperture 17 with two perforated rings which can be rotated relative to one another.
- the jacket 12 is in turn connected to the beginning of the enlarged, second section 6 of the mixing tube 4 via radial lines which are arranged between the axially parallel lines 18. Due to the injector action on the step-shaped extension 7 of the mixing tube 4, the mixture of cooled exhaust gas from the boiler and combustion air emerging from the radial lines mixes well with the hot gas mixture emerging from the first section 5 of the mixing tube 4.
- a substoichiometric atmospheric oxygen-fuel ratio ( ⁇ 1) is set in the first section 5 of the mixing tube 4.
- regulation takes place by means of corresponding control valves in the air and / or oil supply line to the burner, as will be explained further with reference to FIG. 2.
- the regulation takes place via the ring aperture 17.
- An ionization probe IS monitors the combustion temperature in the combustion chamber 8.
- An ignition device 19 is arranged in the area of the aperture 3 in the oil burner.
- Thermal insulation layers 20, 21 provide insulation of the outer jacket 12 of the first section 9 of the combustion chamber 8 with respect to the annular space 13.
- FIG. 2 the gas, oil and air lines are shown with solid lines and the electrical control lines with dashed lines.
- the oil burner is designated in FIG. 2 with B, the boiler with K and a process control unit with P.
- NT-ART low-temperature exhaust gas recirculation
- Another line to the oil burner B is used for the supply of heating oil and leads via a pump PU and a control valve to the oil burner B.
- a gas line that is only available in the case of heating with gaseous fuel leads via a control valve to the oil burner B.
- a drive unit M drives the fan G and the oil pump P.
- HT-ARF high-temperature exhaust gas recirculation
- the output lines of the process control unit P lead to a mixing valve air-boiler exhaust gas, to the drive unit M, to the control valve in the oil line and possibly to the control valve in the gas line.
- Another outlet line of the process control unit P leads to the ignition Z of the burner (ignition device 19 in FIG. 1).
