Advanced Materials & Sustainable Manufacturing 2024 , 1, 10003 11 of 14 found that the simulation results are the same as the mechanistic calculations when the heat loss is set to zero, and the module can accurately simulate the surface condenser. The performance is affected when operating parameters such as the temperature and mass of the incoming secondary steam or the temperature and mass of the cold water are changed. Any change in these parameters requires a completely new simulation. In the real production processes, there is a certain amount of heat loss in the heat transfer process. In CADSIM Plus, it is possible to set the heat loss ratio for the equipment to obtain simulation results that are closer to the real situation. Table 6 shows that after adjusting the heat loss ratio for the equipment to 3%, the output term changes in a similar way to the real situation. Figure 8 shows the interface of the surface condenser simulation run, the curves shown in the figure are the variation curves of condensate and temperature. In practical use, real-time data can be imported via EXCEL and the dynamic changes of output parameters can be observed after simulation calculations, and parameter variation curves can be constructed for each parameter in the model interface to provide reference for actual process decisions.
