Abstract

The project began in 1992 and is scheduled to last three years. The aim was to construct a mathematical model for calculating speed distributions, percentage volumes and temperatures of both steam and fibre, and the steam pressure in the plate gap. The framework for the theoretical flow model is now complete. The model, which is 2-dimensional, shows a cross-section of the stator and rotor and the space between them. Flow resistance between the phases, wall friction and turbulence still have to be included and tested. The theoretical model will be tested in practice by making measurements on a SD-65 refiner in production at Kaipola paper mill. In addition to the normal measurements, the refiner is fitted with five radially staggered temperature measurement sensors in the plate gap, together with corresponding sampling devices providing samples of the pulp at these points. Three trial runs have been conducted with the refiner this year. The experimental set-up at Kaipola has proved successful. Work on programming and testing the model is continuing in order to reach the target set
