The majority of all paper machines are rebuilt several times in order to increase production capacity. The“less important”parts such as recuperation, ventilation equilibrium, exhaust heat and sometimes steam and condensate system are not given particular preference. The original concept of energy efficiency has changed dramatically. Because of the complexity of relationships between efficiency, quality and production the energy optimization of a paper machine is not possible without profound analysis of the drying process! The mathematical description in the form of a virtual machine is the shortest and most efficient route to the destination in such tasks. Simulation is the only means by which planned capital investments to boost the drying performance of paper machines (to save energy or increase capacity) can be effectively proven in the pre-project phase. The technical design of planned upgrades is optimized and fine-tuned before the project start to rule out any unpleasant surprises later. The effectiveness of new equipment can be observed in the virtual paper machine using supplier guaranteed parameters. This brings massive and efficient support for all technical issues and reduces project risks significantly. Virtual technology brings higher project profits through lower project costs, optimized solutions and shorter start-up periods.
