The temperature field simulation and energy saving design of ship borne asphalt tank

Traditional asphalt tank has many defects in its structure, which affects the quality of asphalt finished product, so it is necessary to optimize its structure. This paper proposed a method to improve the problems existed in the heating process of traditional asphalt tank, such as uneven heating of asphalt, low heating efficiency, and environmental pollution. This method could simulate the temperature fields of the traditional asphalt tank based on MATLAB PDE toolbox, as well as compare and analyze the means and standard deviation of the two temperature fields. The experimental results show that this method could efficiently solve the problems about uneven heating of asphalt, low heating efficiency, and environmental pollution. Under the condition of enough asphalt liquid, the optimized asphalt tank could utilize lower temperature fuel oil to preserve heat, which finally achieves to save energy, reduce consumption and reduce pollution.
