Main features and applications of industrial air efficient heaters

Industrial high-efficiency air heater is a widely used in the industrial production process of thermal energy equipment, with high efficiency, energy saving, environmental protection and so on. In this article, Hunan HBO will introduce the main features, classification and application scope of industrial high-efficiency air heaters.

1. The main characteristics of industrial high-efficiency air heaters:

• High Efficiency and Energy Saving

High- efficiency air heater for industrial use utilizes electric energy to generate heat energy, and the efficiency of converting electric energy into heat energy is more than 90%, which is much higher than that of traditional heating methods such as coal-fired and oil-fired. Under the same heating effect, the energy consumption of high efficiency air heater is only 1/3 to 1/4 of the traditional heating method.

• Safe and Environmentally Protection

High-efficiency air heater adopts electric heating method, no combustion, no smoke, no harmful gas emission, no pollution to the environment. At the same time, the heating process will not produce open flame, higher safety performance.

• Good Controllability

High-efficiency air heaters can realize the control and regulation of the heating process by adjusting the voltage, current and other parameters to meet the requirements of different process conditions.

• Adaptable

High-efficiency air heater has a wide range of adaptability to different working environments and process requirements. It can work under low-pressure or high-pressure conditions, can be used in humid or dry environments, and has good heating effect on air, flue gas, steam and other media.

• Easy Maintenance

The structure of high efficiency air heater is simple and easy to maintain. There is no complex equipment such as burner, chimney, etc., and the maintenance workload is small.

2. Classification of high efficiency air heaters for industrial use:

According to the heating method and structural characteristics, high-efficiency air heaters can be divided into the following categories:

• Resistance Heaters

Resistance heater is a kind of high-efficiency air heater, which generates heat by passing electric current through a resistance wire, and the heat is transferred to the heated object by radiation, convection and conduction. The heating efficiency of resistance heaters is low, and they are suitable for occasions where the heating temperature is not high and the heating speed is slow.

• Induction Heaters

Induction heater is another kind of high efficiency air heater, which generates heat from metal workpiece by magnetic field induction principle. Induction heaters have high heating efficiency and are suitable for applications with high heating temperatures and fast heating speeds.

• Infrared Heaters

An infrared heater is a device that uses infrared heating to warm the object being heated by infrared radiation energy. Infrared heaters have a high heating efficiency and are suitable for applications that require rapid heating.

• Microwave Heaters

Microwave heater is a kind of equipment that utilizes microwave energy to heat up the object to be heated by microwave energy. Microwave heaters have high heating efficiency and are suitable for occasions where rapid heating is required.

3. Range of applications for industrial high-efficiency air heaters:

Industrial high-efficiency air heaters are widely used in various industrial fields, such as chemical, petroleum, metallurgy, electric power, machinery, food, building materials and other industries. High-efficiency air heater can be used for air preheating, gas purification, drying, melting, conveying, heating, heat treatment and other processes.

Industrial high-efficiency air heater is characterized by high efficiency, energy saving and environmental protection, and plays an important role in the industrial production process. With the continuous development of technology and the continuous expansion of the application, the application scope and effect of high-efficiency air heaters will be further improved.
