Paper Factory Energy Recovery
The boiler needs to consume a lot of air during the combustion process. Before combustion, the air at room temperature needs to be heated to about 300 °C, and then the air participates in the combustion. The heating process of the air also consumes a part of the fuel combustion energy.
After the flue gas waste heat recovery air preheater is installed, the high temperature flue gas passes through the surface of the heat pipes installed side by side in the air preheater before being discharged into the atmosphere, and through the heat pipe effect, the cold air entering the boiler is preheated. During the process, the temperature of the high-temperature flue gas decreases, the temperature of the cold air increases, and the heated air enters the boiler to participate in the combustion, reducing the fuel consumption of the part that originally heated the air.
