Finned tube type steam heat exchanger

What are finned tube type steam heat exchangers?

Finned tube steam heat exchangers can be used in factories and workshops for steam heating, hot water heating, or heat transfer oil heating, as well as as the drying element of drying equipment and heat dissipation equipment of drying rooms, because their internal structure and external dimensions can be designed and customized to meet the actual use requirements. The raw material selection, internal structure arrangement, and matching design of fin tube radiator fins are carried out in accordance with the heat demand required by the actual installation and use environment, in order to determine more appropriate fin tube radiator fins, which is convenient for the use of later installation rooms or the installation and application of drying equipment.

What are the finned tube steam heat exchangers usage?

Finned tube steam heat exchangers have long been used in industrial steam heating. Steel tube steel fins and steel tube aluminum fins are the two most common types of radiating tubes. Steel tube aluminum fins radiating tubes are occasionally used as raw materials for food drying, whereas steel tube steel fins radiating tubes are used as raw materials for industrial products drying, wood products drying, and so on. Grain drying, tobacco and tea drying, rapeseed drying, vegetable dehydration drying, paper specific and printing and dyeing equipment drying are the most commonly used drying materials in the drying room. 

What are finned tube steam heat exchangers structure?

According to the shape and structure of fins, finned tubes are classified into the following categories: square finned tubes, spiral finned tubes, longitudinal finned tubes, spiral serrated finned tubes, and inner finned tubes. The steel high frequency welded finned tube radiator is a type of inner core formed by electric welding the high frequency welded finned tube to both sides of the water tanks.

The overall structure of finned tube type steam heat exchangers.

The steam heat exchanger mainly consists of four parts:

Finned tube type steam heat exchangers Part I finned tube

There are two types of finned tubes in the steam heat exchanger: the first is steel finned tube, which is a circle of wavy fins wound on the outer wall of the steel tube. The fins are closely contacted with the steel tube through the winding machinery, and the heat is exchanged through the winding contact surface; the second is steel aluminum composite finned tube, which is rolled by the rolling machinery The aluminum tube is sheathed on the outside of the steel tube and enters the rolling machine. The aluminum tube is rolled into a circle of aluminum fins by the rolling tool.

Finned tube type steam heat exchangers Part II framework

After the fin tube is completed, the fin tube is fixed on the end plate frame of the steam heat exchanger. This arrangement is not a normal parallel arrangement, but a cross dislocation arrangement. The purpose is to achieve turbulence and enhance the heat transfer characteristics of the gas.

Finned tube type steam heat exchangers Part III connection

After the fin tube is placed, the elbow is used to connect the fin tubes together to achieve the continuity of the fluid channel in the fin tube.

Finned tube type steam heat exchangers Part IV import and export settings

When the steam heat exchanger is arranged, the steam enters from the upper end of the equipment and exits from the lower end of the equipment.
