The aim of the project is to develop options to lower the back pressure in complex steam systems while maintaining full supply of the heat load. In the course of the research project at the three participant paper mills the options to reduce the back pressure of the steam and consequently the potentials to increase the generated electricity of particular plants are analysed.

Description

The following steps are carried out in order to reach the project target:

• Data acquisition at electricity generating plants
• Identification of all important steam consumers (amount, pressure and temperature)
• Determination of options to reduce the pressure level for particular consumers
• Simulation of the higher electricity yield using variable back pressure

These steps are carried out for Austrian sites of the following 3 companies:     

• Mayr-Melnhof
• Mondi
• Sappi
