Boiler Heat Recovery Heat Exchangers

Boiler Heat Recovery Heat Exchangers

Boiler heat recovery heat exchanger is a device that can effectively improve the efficiency of energy use.

The boiler will produce a large amount of high-temperature flue gas in the process of operation, which contains considerable heat. Heat recovery heat exchanger using the principle of heat exchange, the heat in the high temperature flue gas to the medium to be heated, usually water or air.

Specifically, the interior of a heat exchanger usually consists of a series of tubes or plates. The high temperature flue gas flows on one side, while the medium to be heated flows on the other side. Through the walls of the pipes or plates, heat is transferred from the high-temperature flue gas to the medium, raising the temperature of the medium. After heat exchange, the low-temperature flue gas is discharged from the heat exchanger, and the heated medium can be used for other purposes, such as heating, hot water supply and so on.

Field of Application

Industrial field

In industrial production, many processes require large amounts of thermal energy. By installing a boiler heat recovery heat exchanger, the heat in the flue gas of the boiler can be recovered and used to preheat process water, air or other media, thus reducing energy consumption and improving production efficiency.

For example, in the chemical, paper and food processing industries, heat recovery heat exchangers can recover heat from boiler flue gases for heating reactors, drying equipment, steaming equipment, etc., thus reducing dependence on external energy sources.

Civil field

In civil buildings, boiler heat recovery heat exchangers can be used for heating and hot water supply. By recovering heat from boiler flue gas, it can improve energy utilisation efficiency and reduce energy costs, as well as reduce pollution to the environment.

For example, in residential districts, hotels, hospitals and other places, the heat recovery heat exchanger can recover the heat in the boiler flue gas to be used to heat the circulating water of the heating system or to provide domestic hot water, so as to achieve the purpose of energy saving and emission reduction.
