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.
