Based on this principle, the mathematical model of an exothermic reactor is established to caculate Exothermic reator length L corresponding to reation temperature T, reation temperature T corresponding to ammonia mole fraction y and the average internal reactor wall temperature Tave corresponding to exergy output Enet and thermal power output Q. The curves of L-T, T-y, Q/Enet –Tave are drawn with the caculated date which can directly reflect the influence of reactor inlet gas temperature and reactant flow rate on ammonia synthesis reaction for the reactor under the conditions of definite design pressure and hydrogen/nitrogen ratio. Furthermore, the design parameters to realize maximum exergy output and thermal output are presented.
