Abstract
The Finnish forest industry consumes electric power about 20 TWh/a. This is about a third of the total power consumption of the nation. The power consumption does rapidly increase. The aim of the Raina program was to improve the international competitiveness of the domestic paper industry and machinery suppliers by energy-technological means as well as to compensate the increase in energy consumption due to product grade development. The research was targeted into the subprocesses with highest energy consumption: thus even the minor percentual improvements may lead into large absolute savings. Promising areas are especially the pumping of pulp slush and water, vacuum system, pulp beating and refining and infrared drying of the paper web. Part of the projects dealt with the mechanical removal of water from the web (wet pressing) and web drying. The program did also include projects with indirect energy effects, e.g., due to improvement of production efficiency or evenness of product quality - leading to smaller amount of rejected production. Several commercially ready new machines were developed, the use of which can lead to direct or indirect improvement in energy efficiency of the process. Some projects have developed analysis and calculation methods that can be used for
