There are at least two different temperatures in the heat exchanger, one kind of fluid temperature is higher, the heat is released, the other is the temperature is lower, and the heat is absorbed. In engineering practice, there are sometimes two or more fluid to participate in the heat exchanger, but its principle is not essential difference.In the design of the heat exchanger, the type of the application should be selected according to the requirements of the process, then the heat transfer area of the heat exchanger is calculated, and the structure size of the heat exchanger is determined. Design of heat exchanger fixed tube heat exchanger the experimental application of tubular heat exchanger, which is suitable for the temperature difference or temperature difference but the shell pressure is not high. In order to complete the 49 thousand tons of kerosene production tasks, the process of heat exchanger design mainly includes the contents as follows: to determine the design scheme of heat exchanger according to the relevant r
