Heating method of large vertical storage tank

In the petrochemical industry and other industries, large vertical storage tanks are often used to store various production raw materials, usually storing high melting point, and the medium that is easy to crystallize at room temperature can be exported and transported after heating. This involves the warm heating of large vertical storage tanks. The heating system is an auxiliary facility for heating large vertical storage tanks, and it is often necessary to design the tank external heating coil or internal heating coil system.

Large-scale vertical storage tanks mostly use internal tank bottom heating coils to heat the medium stored in the storage tanks. The heating coils are mostly smooth tube structures arranged around the bottom of the tank. Commonly used heating methods include hot oil circulation heating method and hot water steam circulation heating method. The hot oil circulation heating method is to continuously extract part of the liquid medium from the storage tank, and then return it to the container to mix with the medium in the tank after heating, and the heat is quickly transferred through mechanical stirring. The hot water steam circulation heating method is to pump steam or hot water into the heating coil through a mechanical pump, so that the heating coil in the large vertical storage tank heats up the medium in the tank.
