在能源紧张的环境下，蓄热式电锅炉利用低谷电加热蓄热体耐火砖材料将不能存储的电能转化为热能暂时贮存起来，通过二次换热转化为用户可以利用的能源。蓄热体工作过程分为加热、保温、放热、保温、再加热的循环过程。放热过程是蓄热体工作的主要阶段，放热量的大小和时间长短直接影响设备的工作状态。通过对蓄热体模型的简化，建立三维模型，采用ANSYS Workbench中的Fluent模块对蓄热体的放热过程做了数值模拟，得到了蓄热体放热过程出口温度的分布情况。得到的结果和某工厂的电锅炉实际工作温度和时间相吻合，通过对蓄热体材料、加热时间等一些参数的设置得到的模拟结果对实际生产具有一定的指导意义。

In the energy crisis of environment ,regenerative electric boiler uses valley power to heat regenerator firebrick material,Which turns electrical energy unable to be stored into heat energy temporarily ,then convert the available energy applied by the user through the secondary heat transfer. Regenerator work process consists of heating ,insulation,heat release,insulation and reheat cycle. Exothermic process is the main stage of regenerator work ,the size and time of the heat release directly influence the working status of equipment. By simplifying the model of the regenerator ,we build 3D model, then make numerical simulation on the exothermic process of regenerator using the Fluent module of ANSYS in workbench. Finally,we get the distribution regenerator outlet temperature exothermic process. The obtained results are consistent with the practical work temperature and time of a factory. The simulation results which are gotten from some set parameters such as the regenerative materials ,heating time etc have certain guiding significance on practical production.
