Flue Gas Waste Heat Recovery Heat Exchanger

Product Details:

With the continuous development of industry, the waste gas, flue gas and harmful substances generated by factories during production and operation have caused serious pollution to the environment. In order to improve environmental quality and reduce the emission of harmful substances, research on industrial flue gas treatment equipment has received more and more attention in recent years.

As a high-efficiency flue gas treatment equipment, the flue gas waste heat recovery heat exchanger can not only effectively recover the waste heat in the flue gas, but also reduce environmental pollution and improve energy utilization efficiency. This article will give a detailed introduction to the flue gas waste heat recovery heat exchanger.

I. Working principle of flue gas waste heat recovery heat exchanger

The flue gas waste heat recovery heat exchanger uses the heat exchange principle to transfer the heat in the flue gas to the cold fluid (such as water or air) to heat the cold fluid, thereby realizing the recovery and utilization of flue gas waste heat. The working principle mainly includes the heat transfer principle and the heat exchange process between flue gas and cold fluid.

Heat transfer principle: The heat transfer principle mainly includes three methods: heat conduction, convection and radiation. In the flue gas waste heat recovery heat exchanger, heat transfer is mainly carried out by convection and radiation.

Heat exchange process between flue gas and cold fluid: Flue gas enters from the flue gas inlet of the heat exchanger, exchanges heat with the cold fluid, and reduces the temperature of the flue gas; at the same time, the cold fluid absorbs the heat in the flue gas and increases its own temperature. The flue gas after heat exchange is discharged from the flue gas outlet, and the heated cold fluid can be used for various purposes such as power generation and heating.

II. Types of flue gas waste heat recovery heat exchangers

According to different classification standards, flue gas waste heat recovery heat exchangers can be divided into many types. Common classification methods are mainly the following:

Classification by heat transfer method: It can be divided into partition heat exchangers, mixed heat exchangers and heat storage heat exchangers.

Classification by the flow direction of flue gas and cold fluid: It can be divided into co-current heat exchangers, countercurrent heat exchangers and cross-current heat exchangers.

Classification by the structural form of the heat exchanger: It can be divided into shell and tube heat exchangers, plate heat exchangers and spiral plate heat exchangers, etc.

III. Advantages of flue gas waste heat recovery heat exchanger

Energy saving and consumption reduction: By recovering the waste heat in the flue gas, the energy utilization efficiency can be improved and the production cost can be reduced.

Reduce environmental pollution: Reduce the flue gas emission temperature and reduce the content of harmful substances in the flue gas, which is beneficial to environmental protection.

Improve equipment operation efficiency: The flue gas waste heat recovery heat exchanger can effectively reduce the flue gas resistance and improve the operation efficiency of the equipment.

IV. Application fields of flue gas waste heat recovery heat exchanger

Flue gas waste heat recovery heat exchanger is widely used in chemical, petroleum, electricity, steel, metallurgy, textile and other industrial fields. In these industries, a large number of industrial furnaces, boilers and other equipment contain rich waste heat resources in the flue gas. Through the flue gas waste heat recovery heat exchanger, these waste heat can be effectively recovered and utilized to achieve the purpose of energy saving and emission reduction.
