[0002] A boiler is a heat exchange device that uses fuel or other energy sources to heat water or other liquids into steam or hot water. During the operation of the boiler, high-temperature flue gas is generated. The high-temperature flue gas needs to be cooled by a flue gas condenser and then discharged through a pipeline. The boiler flue gas condenser can recover the heat in the water vapor and the heat in the flue gas in the boiler flue gas to achieve efficient energy utilization and environmental protection.
