The heat transfer properties of black liquor from wheat straw pulping in a tank with agitator were studied by changing the experiment conditions including temperature-difference driving force, geometry shape of the tank and agitator speed. The heat transfer properties of the black liquor which had different physical properties and rheological properties, and with different fluid kinetic conditions and the space geometry characteristics of fluid flow were investigated. Furthermore, the mathematical models and evaluation criteria for heat transfer of wheat straw black liquor based on the conventional methods and artificial neural networks were established. The experimental results showed that the factors mentioned above have obvious effect on the heat transfer property of black liquor from wheat straw pulping.
