摘　　要：建立了适用于工程应用的蒸汽蓄热器放热压力的数学模型 ,并进行了动态仿真计算 ,计算结果和实验测得值的比较表明 ,该模型能正确反映蓄热器放热过程的动态特性。将喷射泵引入蒸汽蓄热系统 ,建立了蒸汽喷射泵式蓄热器系统的数学模型 。Steam injector is introduced into heat accumulator system.Based on the mathematic model of steam accumulator,which is adapted to practical utilization,the transient simulating calculation is made out on the condition of experiment initial parameter.By comparison with the experiment test figure,it is shown that the model correctly reflects the transient character of discharging process of heat accumulator and the system is feasible.
