What Is Plate Air Preheater?

An air preheater is an important piece of equipment used to improve the heat exchange performance of a boiler.

Its main function is to utilise the heat of the flue gases in the tail flue of the boiler to preheat the air entering the boiler.

This has several benefits:

Improve combustion efficiency: the preheated air is better able to mix with the fuel and burn it, resulting in a more complete combustion.

Improve boiler thermal efficiency: less heat is wasted and the heat energy in the flue gas is effectively utilised.

Reduce energy consumption: under the same output power, the amount of fuel used can be reduced.

There are various types of air preheaters, such as tubular air preheaters, rotary air preheaters and so on. They differ in structure and working principle, but the purpose is to achieve efficient heat transfer between air and flue gas.

For example, in thermal power plants, the air preheater is a key component of the boiler system, which has an important impact on the operational efficiency and economy of the whole plant.

Air preheaters play an important role in energy use and industrial production, and are important for energy conservation and emission reduction and improving production efficiency.
