Abstract
The invention comprises a method and a system in a paper machine, and also a software product, allowing one or more tools to be generated for indicating the state of the paper production process in terms of energy consumption to the operating staff of the paper machine. This allows continual monitoring of the state of the paper production process and/or its energy efficiency combined with efforts to develop the manners of running the paper machine and its dryer section in a more favourable direction. In one embodiment of the invention, the dry solids content DSC of the press section can be calculated by means of the evaporation amount of the dryer section, the production of finished paper and the final paper moisture as follows: DSC=m/(m+m), in which mis the dry mass flow of the paper web to the dryer section and mis the water mass flow to the dryer section. mis obtained by summing up the mass flow of the water discharged from the dryer section and the evaporated water mass flow.
