This invention discloses a simulation method and related equipment for ammonia energy storage based on the local non-thermal equilibrium method, belonging to the field of thermochemical energy storage in solar tower power plants. This method constructs a three-dimensional model of the ammonia decomposition reaction tube, which overcomes the shortcomings of the two-dimensional model, which can only show the temperature and ammonia mass fraction at the cross-section of the ammonia decomposition reaction tube with the axial direction and radius. It can reflect the temperature and ammonia mass fraction at the cross-section of the ammonia decomposition reaction tube with the circumferential angle. The invention proposes to use the local non-thermal equilibrium method to study the ammonia decomposition reaction tube on the heat-absorbing side of the solar thermal ammonia energy storage system, replacing the traditional continuous homogeneous medium model. Due to the different heat transfer characteristics, there is a temperature difference between the gas and the catalyst particles in practical applications. Studying the temperature change laws of the gas and catalyst particle sides separately can obtain more accurate results and reveal the energy transport characteristics of the thermal-chemical energy conversion of ammonia energy storage more profoundly.

This invention provides a solar thermal power generation tower with variable cross-section and variable slope hybrid reinforcement featuring spiral stirrups, comprising a tower body, a steel reinforcement cage, and top embedded parts. Both the steel reinforcement cage and the top embedded parts are embedded within the tower body. The top embedded parts connect to the upper steel structure system of the heat-absorbing tower. The lower and upper parts of the tower body are cast using UHPC (Ultra-High-Pressure Polymer), while the middle part is cast using conventional concrete, with the strength grade of the conventional concrete being lower than that of the UHPC. The reinforcement cage includes two layers: an outer layer composed of FRP spiral stirrups and FRP longitudinal bars, and an inner layer composed of longitudinal steel bars and steel spiral stirrups. The cross-sectional area of ​​the tower body gradually decreases along its height, and the outer surface of the tower body gradually tapers from bottom to top. The UHPC casting provides sufficient load-bearing capacity for the upper structure, while the outer reinforcement cage uses FRP material to improve the corrosion resistance and tensile strength of the tower structure, reduce steel usage, and ensure the stability of the tower structure.
