Numerical Simulation of Ammonia-Based Exothermic Reactor Used in Solar Thermal Power Generation

Long Xin-feng Liao Kui(Key Laboratory of Enhanced Heat Transfer and Energy Conservation of the Ministry of Education,South China University of Technology,Guangzhou 510640,Guangdong,China)  
In the all-solar thermal power generation,the thermochemical energy storage is a key step.In this paper,the choice of energy storage system is analyzed and the basic principle of ammonia-based thermochemical energy storage is introduced.Based on this principle,a mathematical model of an exothermic reactor(ammonia-synthesizing reactor) is established to obtain the curves of the exothermic reactor length versus the reaction temperature,of the reaction temperature versus the molar fraction of ammonia and of the average internal reactor wall temperature versus the exergy and heat energy outputs.Thus,the effects of the inlet gas temperature and flowrate on the ammonia-synthesizing reaction under definite design pressure and hydrogen-to-nitrogen ratio are directly reflected,and the optimized operation parameters to realize maximum exergy and heat energy outputs are determined.Simulated results indicate that the average temperature of the catalyst bed in the reactor is an optimal control parameter to rea-lize maximum exergy and heat energy outputs,and that the exergy and heat energy outputs reach their maximum va-lues at 850 ℃ and 650 ℃,respectively.
