The flow rate of the molten salt pump is related to exchanging heat quantity. If the exchanging heat quantity is greater, the flow of molten salt pump is larger. At the same time, if you want to determine the flow of molten salt pump, you refer to heat transfer coefficient of heat exchange equipment and Process of chemical system. The above is just a qualitative introduction, we should know that the flow of molten salt pump will have different in different process system. So we should accord to experience of correction.
