Product features:

(1) High thermal conductivity tube made from low-dimensional carbon-based composite material is adopted for the low-temperature flue gas exchanger, which has the advantages of corrosion resistance and low resistance drop.

(2) Waste heat of the flue gas is used for heating by utilizing the principle of phase change in gravitational field, so that the heat transfer efficiency is high, the heat exchange area is small, and the investment cost is low.

(3) Service life of the product can reach 20 year.

At present, the temperature of the flue gas at the outlet of the bag dust remover in the power plants is about 130-150 ℃. If the flue gas directly enters the desulfurizing tower, it needs to be cooled by a large amount of spray water, which will cause a lot of heat waste. A low-temperature flue gas heat exchanger is set before the desulfurizing tower to recover the waste heat of the flue gas and reduce the temperature of the flue gas before entering the desulfurizing tower. When the flue gas temperature drops below the acid dew point, the traditional metal tube type low temperature flue gas heat exchangerwill suffer low-temperature corrosion and lose efficiency, thus shortening its service life.

The low-temperature flue gas exchanger can effectively solve the problem of dew point corrosion. Meanwhile, the flue gas is cooled from 130 ℃ to 70 ℃, and the released heat can be used to preheat the system of the heat supply network water in winter, which can increase the water temperature of the pipe network water from 50 ℃ to about 75 ℃.
