35510 Butzbach Management process for an open anode furnace The present invention relates to a management process for an open anode furnace in accordance with the pre-characterising part of Clause 1. as well as to a device for measuring the operating status of an open anode furnace and for managing its process in accordance with the pre-characterizing part of Clause 5.
Ts date, an open or covered anode furnace has been operated in such a way that the specialist personnel operating the anode furnace have to rely on many years of professional experience to enable the workers to control the anode furnace.
This means that the specialist personnel responsible for operation regulate the burner power, for example, in order to increase or reduce the temperature in the burner zones. The temperature is measured at various points in xhe anode furnace for this purpose.
However, an anode furnace control method of this type has the disadvantage that the specialist personnel are often unable to achieve the optimum operating setting of the anode furnace because information is lacking. This is because the parameters that are decisive in terms of optimum energy utilization can only be inadequately assessed and estimated by the specialists. For example, it is conceivable that an obstacle could occur within the air duct that could under certain circumstances cause a local reduction in the volume of air passing through this area of the anode furnace, leading to a rise in temperature wheroas there may be a drop in temperature at

However, an anode furnace control method of this type has the disadvantage that the specialist personnel are often unable to achieve the optimum operating setting of the anode furnace because information is lacking.

For example, it is conceivable that an obstacle could occur within the air duct that could under certain circumstances cause a local reduction in the volume of air passing through this area of the anode furnace, leading to a rise in temperature wheroas there may be a drop in temperature at
2 another point. Even increasing the burner power has no effect in the event of a reduction in the throughput of air in the area of the burner, because the lower amount of heating air available does not transport the additionally input burner energy to the anodes immediately with the effect that the burner energy is applied to the walls of the anode furnace_ This, however, leads to significant damage to the anode furnace because the walls of the anode furnace are not designed to withstand such an elevated level of heat stress.
Furthermore, it is disadvantageous that the personnel operating the anode furnace cannot reliably estimate at what moment a section of the anode furnace has laecome unusable and therefore must be renewed. Instead, such decisions have in the past been based on statistical observations and values drawn from experience, which in some cases has led to a section being renewed too soon or even too late. This causes unnecessary operating costs because the energy consumption increases.
Furthermore, it is highly costly to operate a faulty section or a section which is not being used optimally in terms of energy because the anode furnace requires additional energy in order to burn the anodes it 'contains.
To date, no device far automatic control of a.n anode furnace has been disclosed.
It is therefore the task of the present invention to provide a management process for an anode furnace of the aforementioned type, by means of which the anode furnace can be operated automatically over a relatively long period. This process is intended to provide measuring parameters by means of which an electronic control unit automatically undertakes the process management of the anode furnace. Also, the service life of the anode furnace should be extended because the process management remains within an optimum energy band. Furthermore, it is the task of the present invention to provide a device by means of which the process management of the anode furnace can be undertaken.
The task in accordance with the present invention for managing the process of the anode furnace is accomplished by the features of the characterizing pacts of patent claims 1 and 5, and the task for automatic process management of the anode

3 furnace is accomplished by the device in accordance with the characterizing park of patent claim 6.
Further advantageous embodiments of the invention are apparent Pram the' subordinate claims.
By means of the device and process in accordance with the present invention, it is possible to measure a heating duct index that is permanently adjusted to the actual operating situation in the anode furnace. In this case, an electronic control unit allocated to the device evaluates the measurement results and compares these with a predefined or mathematically calculated actual operating condition, and adapts the actual operating status to the optimum actual value of the anode furnace. This provides an advantageous way of obviating the need for specialist personnel in order to monitor and conduct the process management of the anode furnace. Rather, the process management of the anode furnace can be based on precisely predefined values so as to make it possible to operate the anode furnace with optimum use of energy.
Also, the relevant parameters are determined in each section of the anode furnace so that it is possible to verify clearly in which section which actions have to be taken.
For example, the electronic control unit increases or reduces the air throughput through the anode furnace in accordance with the volume of air actually needed in the individual zones. If necessary, it is also possible to increase or reduce the quantity of fuel in order to control the output of the burners so as to achieve the optimum energetic temperature required for combustion of the anodes.
Consequently, the process management of the anode furnace takes place fully automatically and requires only minor manual checks, for example to see whether the measuring instruments used are in need of repair and that they are delivering correct measurement values. As a result, a fully automatic furnace process management of this kind only requires a small number of personnel which allows considerable personnel cost savings.

The drawing shows a sample embodiment configured in accordance with the present invention, the details of which are explained below.

Figures 1 to ~ show an 2~ns~de furnace 2 to which a device 1 for process management is allocated. The device 1 is intended to allow the anode furnace 2 to be controlled automatically without the need for extensive monitoring activity by the operating personnel.
The anode furnace 2 shown in Figure 1 consists of three individual fires with an identical structure. The structure and the mode of function of the anode furnace 2 is explained in more detail using the first fire. Each fire can be divided into three zones 3, 4 and 5 within which different operating Conditions obtain. A plurality of anodes 7 that are to be burned are placed in one section 6 each in zone 3. In zone 4, the positioned anodes 7 should be burned by three burners 10 and the burned anodes should cool 7 in zone 5.

This means it is necessary for air to be channeled through the anode furnace 2 and through the three zones 3, 4 and 5.

This means it is necessary for air to be channeled through the anode furnace 2 and through the three zones 3, 4 and 5. An air duct 9 is provided in the anode furnace 2 for this purpose and it connects the individual sections 6 and therefore also the zones 3, ~4 and 5 with one another. Furthermore, one damper flap 13 each is provided at the output and input of the air duct 9 in order to allow the quantity of air sucked into the air duct 9 to be controlled. A ventilator 14 is allocated to zone 3 and to the air duct 9 emerging there, by means of which the air is drawn through zones 3, 4 and 5 so that negative pressure exists in the anode furnace 2. Consequently, air enters zone
5 of the anode furnace 2 with the norms,! room temperature of the surrounding area and cools down the heated anodes 7. Nevertheless, there is a heat exchange between the anodes 7 and the sucked-in air, with the result that the air flowing into zone 4 is heated up. The three burners 10 further heat the air in zone 4, so that the anodes 7 placed there are exposed to the operating temperature required for combustion.
The air flowing onwards into zone 3 therefore has a further elevated temperature, resulting in the anodes 7 placed in zone 3 being preheated.
Once the anodes in zone 4 have been burned up, the burners 10 are moved and transferred to zone 3 in order to burn the anodes 7 placed there. In this way, the anode furnace in its entirefiy represents a closed control loop in which the following procedures occur in a recurring sequence: the three fires burn the positioned anodes 7, the anodes 7 cool down and the anodes 7 are preheated; in a further three zones, meanwhile, the anodes 7 can be placed for burning or the burned anodes 7 can be removed frpm the anode furnace 2.
In order for the furnace management process to be performed automatically, an electronic control unit 12 is allocated to each individual fire In the anode furnace 2.
Furthermore, each of the sections 6 that form zones 3, 4 and 5 contains temperature sensors 1 G, sensors 17 for measuring the air throughput and sensors 20 for measuring the opacity of the air, by which is meant the obtaining soot particle concentration in the air. Temperature sensors 16 and sensors 17 and 20 record measurement values for each of the sections 6 and pass these an to the electronic control unit '12.
The air flowing onwards into zone 3 therefore has a further elevated temperature, resulting in the anodes 7 placed in zone 3 being preheated.

6 ~'he values measured in this way are used by the electronic control unit 1,~
for creating a heating duct index that is made up of the measured temperature andlor the measured volumetric flow of air and/or the quantity of fuel supplied and the combustion capacity of the burners 10 andlor the opacity of the fire generated by the burners 10 andlor the level of negative pressure obtaining in the zone 3, 4, 5 andlor the resulting temperature gradient of the fire generated by the burners 10_ This heating duct index is now compared with an actual operating value of the anode furnace 2 that has an optimum energy level. The electronic control unit 12 makes appropriate adjustments in case there are discrepancies. Following this, the heating duct index is once more compared with the actual operating value.
The heating duct index is adjusted to the actual operating value by the damper flap 13 at the entrance to the air duct 9 being opened or closed further, for example, with the effect that either more or less air enters the anode furnace ~, (f necessary, the burner power of the burners 10 can also be adjusted by reducing or increasing the quantity of fuel. Controlling the ventilator 14 is also another way of increasing or reducing the air throughput. There are also individual dampers 13 in the inside of the anode furnace 2 inside the air duct 9, which means that, in principle, each section 6 can be individually supplied with air.
Figure 4 in particular shows that the individual sections 6 are monitored with the efFect that it is possible to measure precisely which of the sections 6 are running with optimum energy utilizs,tion, or which of the sections 6 may be damaged as a result of the permanent stress caused by fluctuations in temperature and will have to be renewed. These sections 6 are shown as a black field in Figure 4, which ,means the operating personnel can easily find out which of the sections 6 will have to be completely renewed in the next cooling-down phase in order to achieve an optimum use of energy during operation.
