Definitions
- the present invention relates to a camera module for use with a burner, a burner for a shaft melting furnace, in particular for a copper shaft melting furnace, and a method for operating the burner according to the invention.
- Burners for a shaft melting furnace are known in principle from the prior art.
- WO 90/02909 discloses a generic burner with a conical first chamber, an adjoining mixing chamber and a telescoping eyepiece, which extends axially through the burner.
- the burner known from WO 90/02909 has essentially complete combustion and a uniform flame composition, but on the one hand does not meet today's increased environmental requirements and on the other hand does not allow permanent, in particular automatic, flame monitoring.
- a burner with a cylindrical first chamber which comprises a camera arranged behind a glass pane at its end arranged opposite to the combustion chamber.
- the camera is connected to a monitor that an operator can use to remotely monitor the process.
- the object of the present invention is therefore to provide an improved burner compared to the prior art, in particular to provide a burner with which an outlet area of the burner as well as the flame chamber of the shaft melting furnace can be monitored automatically and manually. Furthermore, the object of the present invention is compared to the prior art Technology to provide improved method for operating such a burner.
- the object is achieved by a camera module having the features of patent claim 1, by a burner having the features of patent claim 2, and by a method having the features of patent claim 11.
- the camera module according to the invention is intended for use with a burner which is typically used in a shaft melting furnace, in particular in a copper shaft melting furnace, in order to melt down a material to be melted, such as copper cathodes, etc.
- the camera module according to the invention is arranged on the burner or an observation device of the burner and comprises a housing with a first opening and a second opening which is arranged axially opposite the first opening and is closed with a sight glass; a beam splitter disposed in an optical line of sight extending axially through the housing between the two openings; and a camera, for example a CCD camera, the objective of which is arranged perpendicularly to the optical viewing axis and aligned with the beam splitter.
- the beam splitter advantageously comprises a semitransparent splitter mirror which is arranged at an angle of 45° and which can be mounted in a fixed position on a holder element, for example.
- a 45° beam splitter prism can also be used.
- the camera module according to the invention can be used to automatically monitor the outlet area of the burner and the flame chamber of the shaft melting furnace and continuously evaluate it by connecting it to a computer-aided unit, with the results then being fed to a burner control loop. Process disruptions can thus be identified more quickly and production downtimes can be effectively reduced by avoiding major accidents.
- the structure of the camera module according to the invention simultaneously allows manual monitoring, which can be carried out by an operator as an alternative or in addition, for example to verify a process fault identified via the camera of the camera module.
- the invention includes a burner for a shaft melting furnace, in particular for a copper shaft melting furnace.
- the burner according to the invention comprises a monitoring device with an optical viewing axis extending through a first chamber, a burner nozzle and a radiant tube of the burner, via which a combustion chamber of the shaft melting furnace can be monitored; and a camera module according to the invention arranged on the observation device.
- the burner according to the invention comprises a monitoring device with an optical viewing axis extending through a first chamber, a second chamber, a burner nozzle and a radiant tube of the burner, via which a combustion chamber of the shaft melting furnace can be monitored; and a camera module according to the invention arranged on the observation device.
- the observation device comprises a tube which extends axially through the first chamber, with a first end of the tube being arranged outside the burner and being connected to the camera module, preferably via an adapter device of the camera module.
- a second end of the tube is arranged in a central opening of a mixing nozzle, which is positioned in an outlet opening of the first chamber and is locked, for example, by means of a bayonet lock.
- the outlet opening is preferably arranged at a distal end of a conically tapering section of the first chamber.
- the first chamber includes an inlet opening through which an oxygen-containing gas, such as air, oxygen-enriched air or pure oxygen, the Burner can be fed, and a fuel gas line which opens into the first chamber and via which a fuel gas can be fed to the burner.
- an oxygen-containing gas such as air, oxygen-enriched air or pure oxygen
- a fuel gas line arranged coaxially around the tube of the observation device is particularly advantageous. It is therefore preferably provided in this context that the combustion gas line is arranged coaxially around the tube of the observation device and at its end oriented towards the mixing nozzle comprises a plurality of nozzle openings which are particularly preferably arranged distributed over its circumference. Each of the plurality of nozzle openings is aligned at an angle of 40° to 50°, preferably at an angle of 45°, relative to the visible or longitudinal axis of the burner in order to achieve a particularly high first blend between the fuel gas flowing out of the nozzle openings and to achieve the oxygen-containing gas.
- the fuel gas line By arranging the fuel gas line in the conical section of the first chamber, which serves as a collection chamber for the oxygen-containing gas, the fuel gas is premixed with the oxygen-containing gas.
- the premixed combustible gas mixture then flows through the mixing nozzle arranged in the outlet opening and is then homogeneously mixed in the mixing chamber, which advantageously has a specific mixing geometry.
- the entire mixing nozzle is designed in such a way that it causes a particularly low pressure loss of only 70 mbar. The ultimate result of this is that the permanent loss of pressure at the burner can be continuously kept to a minimum, as a result of which the burner has a better energy balance compared to burners known from the prior art.
- Gases containing hydrocarbons in particular methane or natural gas, hydrogen or mixtures thereof, are particularly suitable as fuel gases.
- the mixture for example one of natural gas or methane and hydrogen, is advantageously individually premixed in the range from 1 to 100% by volume, for example in a valve station, and then fed to the burner via the fuel gas line.
- One advantage of adding hydrogen to the hydrocarbon-containing gas is that it is possible to react flexibly to rising CO2 prices in the future. This is particularly preferred provided that the hydrogen was obtained using renewable energies.
- the mixing nozzle causes a particularly low pressure loss, which has an advantageous energetic effect on the operation of the burner.
- the low pressure loss is achieved here via the specific mixing geometry, which is advantageously formed by a plurality of blades arranged in the ring-shaped mixing chamber.
- the ring-shaped mixing chamber has an outer ring with preferably a first set of blades arranged radially on the outside and an inner ring with preferably a second set of blades arranged radially on the inside, the two sets of blades being arranged in opposite directions to one another.
- the blades of the first and second set are arranged relative to each other such that each blade of the first set forms three shear planes with three blades of the second set or each blade of the second set with three blades of the first set.
- the burner nozzle which advantageously comprises a plurality of guide vanes, is arranged at the end of the second chamber arranged axially opposite the mixing nozzle. These are arranged in a front area of the burner nozzle in the direction of flow.
- the guide vanes are designed and aligned with one another in such a way that the combustible gas mixture is driven to the center of the duct, which specifically generates turbulence in the center area and thus prevents free flow of the combustible gas mixture.
- the burner nozzle In the area at the rear in the direction of flow, the burner nozzle then has a conically tapering outlet opening, the edge of which, according to an advantageous embodiment variant, has a jagged structure, in particular one provided with recesses, via which turbulence can be generated in a targeted manner, which leads to the formation of a stable flame root leads.
- an ignition ionization candle is provided, which is arranged just behind the edge and can advantageously be continuously monitored via an ionization monitor. For this it is necessary that the alarm wire is always positioned in the flame over the entire output range of the burner. Due to the formation of the stable flame root, this can be guaranteed at all times.
- the present invention also relates to a method for operating the burner according to the invention, with the camera module continuously monitoring an inner surface of the radiant tube by comparing the detected individual recordings with a reference recording and, if an actual value exceeds a setpoint value, an automatic acoustic and/or visual warning message is issued.
- an automatic control system is additionally activated, which throttles the burner output of the burner.
- clogging of the jet pipe with the melted material in particular with copper particles, can be identified at an early stage and appropriate countermeasures can be initiated.
- the burner output can be throttled at the burner, as a result of which the flame becomes shorter and heats up an edge area of the lining of a shaft melting furnace, in particular a copper shaft melting furnace. This melts the adhesions.
- a predetermined value preferably a value of more than 90 percent by area
- the power is increased again.
- Composition of the fuel gas mixture is manipulated, for example by setting it to a lambda value of 1.
- the camera module can also be used to continuously monitor the melt material level by comparing the detected individual recordings with a reference recording and if an actual value exceeds a target value, an automatic acoustic and/or visual warning message is output.
- the camera module records the level of a reflective surface of a so-called “smelting material lake", in particular a “copper lake”, as such a clogging of the burner can lead to time-consuming manual cleaning. If the level of melted material exceeds a critical value, the burner outputs of, for example, an upper row of burners can be automatically reduced in order to reduce the amount of melted material that flows in the shaft melting furnace.
- the brightness of the combustion chamber of the shaft melting furnace in the area in front of the respective burner can also be monitored using the camera module by comparing the detected individual recordings with a reference recording and/or at least one individual recording of another burner arranged in the shaft melting furnace and with an automatic acoustic and/or visual warning message is issued when an actual value exceeds and/or falls below a target value. If a difference in brightness is identified, a maintenance request can be sent to maintenance, for example. Alternatively, the composition of the fuel gas mixture can be adjusted and the identified brightness can be corrected based on this.
