Exporters of flue gas waste heat recovery heat exchangers in Dalian, China

Dalian YDA flue gas heat exchanger, carefully crafted by Dalian Beifang Yida Technology Development Co., Ltd., has outstanding performance in the fields of energy recovery and industrial energy conservation.

Product Features

1.High - efficiency Heat Exchange: It adopts a special finned tube design with good temperature performance. During heat conduction, self - vibration can effectively prevent fouling accumulation, and the ventilation resistance is small, always maintaining high - efficiency heat transfer efficiency, which can greatly improve energy utilization.

2.Convenient Installation: The installation process does not require large - scale modifications to the original boiler or industrial furnace, and can be put into use quickly, reducing equipment downtime.

3.Long - life and Low - maintenance: The super - heat pipe technology ensures that the service life of the waste heat recovery device is more than 10 years. Moreover, single heat pipes can be removed and replaced, with simple maintenance and low costs.

4.Remarkable Energy - saving: For large - scale industrial furnaces, the use of this heat exchanger can increase their efficiency by more than 10%; for small and medium - sized fuel - oil, gas - fired, and coal - fired boilers, the efficiency can be increased by 5% - 10%, with prominent energy - saving benefits.

5.Fast Return on Investment: The payback period is short, usually within 3 to 8 months, which can quickly save costs for enterprises.

Working Principle

1.Gas - water Waste Heat Recovery: The equipment is installed at the boiler flue gas outlet. The lower part is the flue gas channel, the upper part is the water tank, and there is a partition in the middle. Flue gas flows through the flue gas channel and scours the lower end of the heat pipe. The heat pipe absorbs the heat of the flue gas and then conducts the heat to the upper end, thus heating the water in the water tank, which can be used for domestic water heating or boiler makeup water. To prevent ash blockage and corrosion, the exhaust gas temperature of fuel - oil and coal - fired boilers is generally controlled to be not lower than 130°C, and that of gas - fired boilers is not lower than 100°C.

2.Gas - gas Waste Heat Recovery: There are tube boxes around, and the middle partition separates the two - side channels. The heat pipes are full - finned tubes and can be replaced individually. High - temperature flue gas scours the heat pipes upward from one - side channel, and the heat pipes absorb heat to reduce the temperature of the flue gas; cold air scours the heat pipes reversely from the other - side channel, and the heat pipes release heat to increase the temperature of the air. The heated hot air can be used for boiler combustion support or material drying. The exhaust gas temperature at the outlet of the waste heat recovery device needs to be controlled to be not lower than the dew - point temperature.

Application Areas

1.All Kinds of High - Exhaust - Temperature Boilers: It is suitable for all types of boilers with high exhaust gas temperatures and waste heat utilization space, which can effectively recover the waste heat of flue gas and improve the thermal efficiency of boilers.

2.Industrial Heating Furnaces: In industrial heating furnaces in industries such as metallurgy, chemical engineering, and petroleum, when there are low - temperature heat sources available for utilization, this flue gas heat exchanger can be installed to achieve waste heat recovery.

3.Other Waste - Heat - Emitting Equipment: Such as stenter machines, dryers, and kilns in the printing and dyeing industry, which mainly emit energy through flue gas, can all apply this product for waste heat recovery and utilization.

Dalian YDA flue gas heat exchanger, with its advantages of high - efficiency, energy - saving, and convenience, provides strong support for the energy conservation, emission reduction, and sustainable development of various industries.
