Outstanding advantages of air heaters

Air heaters have gradually gained widespread use and have earned the trust of a wide range of users. We previously discussed the key considerations when selecting an air heater. The primary reason for their widespread use is closely related to their performance. Today, we'll explore their key advantages in detail:

1. The air heater system operates at low pressure, using hot water as the medium, resulting in a low temperature.

2. Air heaters can also increase wall temperature, reduce flue gas corrosion, and prevent ash blockage.

3. Compared to heat pipe air heaters, air heaters only require a circulation pump. While this consumes a certain amount of electricity, it is convenient, safe, and reliable.

4. The air heater's circulation pump has a power of 10 kW, equivalent to 4 kg of standard coal per hour, and its heat output is equivalent to the thermal enthalpy of 30 kg of steam.

5. Through continuous circulation of the working fluid, the flue gas is cooled, resulting in effective air heating without the need for steam. The air heater's circulation pump consumes only 10 kW, a minimal proportion compared to the power required to recover heat from the flue gas.

6. The air heater is easy to install and arrange, requiring no modifications to the flue gas ducts. Due to the thermal power requirements of electric air heater heat pipes, the heater is generally located in the air duct above the flue. Forced circulation systems for air heaters can be positioned according to site conditions. The resulting differences in pipe resistance caused by different placements can be addressed by selecting the appropriate air heater circulation pump head.

These are the key advantages of air heaters. I believe you have gained some understanding of the above information and hope it will help you choose the right heater in the future.
