1 SIMULATION SOFTWARE JENAEL 2009 Calculation of electric currents, voltages, system powers and power density distributions in conducting fluids e.g. glass melt to design and optimize electrode configuration and connection of all electric furnaces, electric boosting power distribution and operation, electric feeder heating and related heating systems e.g. in glass melting technology Prof. Dr. Ing. habil. Otto R. Hofmann Jena and Weimar (Germany)

The main program JENA-EL 2009 The use of the software is possible also without any detailed simulation knowledge, without any long training and also after a long break.

3 The main program JENA-EL 2009 The use of the software is possible also without any detailed simulation knowledge, without any long training and also after a long break. Exclusivity of the JENA-EL Software: quick and close to practice calculation of electric heating problems e.g. electro glass melting particularly using galvanically non coupled heating systems (In JENA-EL the voltages vector diagram is a result of the simulation, in other software it must be known.) Further characteristics are: Rod electrodes, free to choose diameter, length and orientation, mean electric conductivity. It takes you ca 5 sec to calculate the electrode currents, the heating sytem powers and total electric power. It takes you 1-5 minutes to calculate the power density distribution. Model Parameter Input The self explaining registries are typical for the easy to handle input data strategy. (3)

Electrode Parameter Input The definition of the electrode positions and their parameters is an other example for the easy to understand values input way.

4 Electrode Parameter Input The definition of the electrode positions and their parameters is an other example for the easy to understand values input way. System Parameter Input The registry System Parameters it s for connecting the electrodes to the heating systems. Voltages Input The registry Voltages Input it s for defining the driving mean voltages. Project Graphics / Tabulation All the given model data, electrodes data and voltage parameters are shown in the Model Data Project Graphics clearly arranged. (4)

5 Calculation of the Electrode Currents After the complete input of the project data and their check up the Menu Registry >Calculate Electrode Currents< becomes free for calculation. The results are given in tables of currents, phases, electrode loads and system powers. (5)

Power Density Calculation The calculation of the power density field may be done after completed electrode current calculation. The calculation area and the preferred grid have to be defined.

6 Power Density Calculation The calculation of the power density field may be done after completed electrode current calculation. The calculation area and the preferred grid have to be defined. For convenience you may choose between the number of grid points (nx, ny, nz) and the grid point distances (dx, dy, dz). The settings are easy to modify. The state of calculation is displayed and the calculated power density field can be saved. (6)

7 Model Graphics for check up the Model Geometry. Vector Graphics (7)

8 Power Density Distribution Graphics Colour or Colour Line graphics of the total values or the normalized values of the calculated power density field. The min, max and mean values are given. (8)

9 Further information The software run is possible directly from the dongle (without any installation on the computer). Without using the dongle the program works / falls down into the DEMO MODE. If whished you may give the project data together with the program to your customers. So they are able to use the program to watch your results online using their own computers. DEMO MODE means that all menu options are to use in spite of the design/generation and calculation of new projects. In that way the software becomes more fit for practice If you want to have your own demonstration calculation or a check of your all electric furnace / booster in operation you should prepare the input data. Molten glass dimensions: (2 X - width Y length Z glass level) Electrodes positions, Diameter, Length : Mean electric Conductivity S/m Electric connection of the electrodes Using JENA-EL you model your electric design (power, system / circuit powers, power density distribution / joules heat distribution, electrode currents, voltages) and get the basic information for ordering transformers and bars / wires. Using JENA-EL you may modify your design / project or your furnace in operation e.g. to install more electric power. Using JENA-EL you are able to check your electric heating system whether the electrodes are correct connected, whether there is any electrode corrosion, whether there are any differences between expected and real currents, power data, heat production areas and other parameters. mail : otto.hofmann@fh-jena.de Prof. Dr.- Ing. habil.
