1. Classification of air flue gas heat exchanger
1. According to the temperature, it can be divided into three models: High temperature air flue gas heat exchanger: used for flue gas above 450 degrees; medium temperature air flue gas heat exchanger: used for flue gas below 450 degrees; low temperature air flue gas exchange Heater: Use for flue gas below 220°C.
2. According to the heat transfer utilization method of the heat exchanger: flue gas-air-water waste heat utilization and recovery, flue gas-steam heat recovery heat exchanger, air-glycol solution heat exchanger, air-water vapor waste heat utilization, air- Water heat recovery, flue gas-water heat exchanger, high-temperature flue gas waste heat recovery heat exchanger, annealing furnace flue gas waste heat utilization, kiln tail gas reuse hot air heat exchanger, reactor oil and gas waste heat utilization heat exchanger.
