Exhaust finned tube heat exchanger

The exhaust finned tube heat exchanger is a heat exchange device that enhances the heat transfer efficiency through the finned tube structure.

The basic heat transfer element is the finned tube, which is composed of a base tube and a fin. The base tube is usually a round tube, but there are also elliptical tubes and flat tubes.

The fins can be designed into various shapes such as flat fins, intermittent fins, corrugated fins and perforated fins according to actual needs, among which corrugated fins and perforated fins are heat exchanger types. The fins can be set outside the tube (external finned tube) or inside the tube (internal finned tube), or even both.

From the structural type, finned tubes can be divided into two basic types: longitudinal and radial, and other types are the development and deformation of these two types.

According to different manufacturing processes, finned tubes can also be divided into integral finned tubes, welded finned tubes, high-frequency welded finned tubes and mechanically connected finned tubes. Each type has its advantages and application scenarios.

Application of exhaust gas fin tube heat exchanger

Waste gas cooling treatment:

In industrial exhaust gas treatment equipment, fin tube heat exchangers are widely used to cool exhaust gas.

Through the heat exchange performance of the fin tube, the exhaust gas temperature can be quickly reduced, which provides convenience for subsequent treatment and purification. This treatment method not only improves the efficiency of exhaust gas treatment, but also reduces energy consumption during the treatment process.

Heat recovery:

Fin tube heat exchangers can also be used as the core component of heat recovery devices to recover and convert heat energy in exhaust gas into useful energy.

This function is of great significance in achieving energy conservation and emission reduction goals. By recovering heat energy in exhaust gas, enterprises can reduce energy consumption and operating costs, while reducing greenhouse gas emissions and contributing to environmental protection.

Flue gas desulfurization and denitrification:

In flue gas desulfurization and denitrification equipment, fin tube heat exchangers also play an important role.
By heating the flue gas, the temperature of the flue gas is increased, and then the desulfurization and denitrification reactions are carried out. This application not only improves the efficiency of flue gas treatment, but also reduces the emission of pollutants, which is of great significance for air quality and protection of the ecological environment.
