For the melting of salts and introduction in the tanks:

    The process lasted several days, with the main problems at the beginning. Until the salts level did not reach the temperature sensors located at a lower position and did not cover the electrical heaters of the tanks, it was not possible to monitor the process at all. Therefore, when defining the instrumentation of the tanks, also the start up process needs to be considered. Sensors in the bottom of the tank and near the pump suction were needed.
    Once the system was monitored, it was possible to see that the heat losses were very high and that it was necessary to mix or recirculate them, but this was not possible in the available installation. Therefore, a mixing or recirculation systems for the salts should be necessary in this type of tanks.
ds to be considered. Sensors in the bottom of the tank and near the pump suction were needed.
