About the three-dimensional temperature Rotary kiln pellet simulations

Article source：

Through the rotary pellet dimensional temperature field simulation, after a period of time in which the experts found that the presence of the two functions.In the calcining process, i.e., toward the outer wall of the Rotary kiln has two ambient cooling function. Two functions that radiation heat transfer and convection heat.Here we will describe in its pellets to illustrate the three-dimensional temperature field changes the situation: 1.Through the gray-scale image, de-noising and feature extraction processing, and then according to the diagram of the Rotary kiln temperature between the brightness and the extraction temperature roasting ball group, so that we can determine from the fundamental and Rotary kiln associated correction value for the specific circumstances of the value Qu.If the cross-section of two-dimensional heat transfer model to calculate the Rotary kiln finite difference method, we can ensure the accuracy of the model solution and the smooth, thereby obtaining pellets and concrete flue gas temperature distribution within the Rotary kiln. 2.According to the actual functioning of the site, for axial gas, pellet temperature distribution of the main-line measurement, the system can also be dynamic display, intuitive understanding of the Rotary kiln thermal conditions.
