3. - The Environmental Managers - Energy Efficiency in IPPC Installations G. Bachmann 3 Agenda Steam and Condensate Systems of Paper Machines Optimisation Possibilities Simulation Experiments Conclusion

4. - The Environmental Managers - Energy Efficiency in IPPC Installations G. Bachmann 4 Steam and Condensate Systems of Paper Machines

5. - The Environmental Managers - Energy Efficiency in IPPC Installations G. Bachmann 5 Optimisation Possibilities There are two main possibilities to identify better operating conditions Simulations Experiments 1.Creating the simulation model 2.Feeding the model with data 3.Correct the model 4.Simulation

6. - The Environmental Managers - Energy Efficiency in IPPC Installations G. Bachmann 6 Creating the simulation model Simulation I

7. - The Environmental Managers - Energy Efficiency in IPPC Installations G. Bachmann 7 Simulation II Feeding the model with data Correct the model

8. - The Environmental Managers - Energy Efficiency in IPPC Installations G. Bachmann 8 Simulation III Correct simulation model

9. - The Environmental Managers - Energy Efficiency in IPPC Installations G. Bachmann 9 Simulation IV

10. - The Environmental Managers - Energy Efficiency in IPPC Installations G. Bachmann 10 Simulation V by partly separating the condensate the cooling water flow is reduced from 24t/h to 2t/h is not heating the cooling water anymore the energy can be used at the level of 133°C the power saving is about 3MW

11. - The Environmental Managers - Energy Efficiency in IPPC Installations G. Bachmann 11 Experiments the experiments must not influence the production or the quality of the product during the experiments all parameters are observed at the process control system

12. - The Environmental Managers - Energy Efficiency in IPPC Installations G. Bachmann 12 Conclusion The results of the Simulation were confirmed by the experiments on the paper machine power saving: 3MW energy saving: 24GWh/a cost saving: 350.000€/a

13. - The Environmental Managers - Energy Efficiency in IPPC Installations G. Bachmann 13 Conclusion Allplan carried out energy efficiency programs called : in Austria Hungary Netherlands Czech Republic Germany Finland Switzerland Romania Slovenia ….... ….and find savings each time
