| 摘 要： | INTRODUCTIONThe heat transfer properties of black liquor (BL)from wheat pulp directly affected the BL recoveryand disposal, Chinese scholars have paid particularaffection to the heat transfer coefficient of blackliquor and its evaporation intensity. The heat transfercoefficient of black liquor is affected by the type ofblack liquor, its available alkali concentration and itssolid content, etc. The heat transfer coefficient ofblack liquor decreased rapidly with the increase inthe solid co…

| Abstract: | The heat transfer properties of black liquor from wheat pulp in a stirring apparatus were studied in this paper. By changing the experiment conditions of temperature-difference driving force, geometry shape and agitator speed, we investigated the heat transfer properties of black liquor from wheat pulp under the conditions of different physical properties, rheological properties, fluid power conditions and the space geometrical characteristics of fluid flow. Furthermore the related mathematical models and evaluation criteria based on the conventional methods and artificial neural networks were established. The experimental results showed that the above-mentioned factors have obvious effect to black liquor from wheat pulp? |
