In view of the current lack of dynamic modeling and analysis of steam modeling in the integrated energy system of industrial parks

the numerical method needs to balance between accuracy and computational efficiency.Based on the basic equation of steam flow

this paper establishes a mathematical model of the hydrothermal process of steam flow. Hydrothermal model is carried out by using a mixture of analytical and numerical methods

and the thermal model is solved by finite difference method for simulation. Compared with the simulation data of commercial simulation software

the solution error of this method is about 0.43%

and the influence of different solution conditions on the thermal process is explored. It was found that an increase in spatial step size would increase the volatility of the temperature curve. As the inner diameter of the pipeline increases

the temperature transfer slows down and the response speed of the model decreases; The initial pressure does not have a significant impact on the solving process and accuracy of the model.
