Laser Welded Finned Tube for Modification of Bolier
Murphy Thermal Energy (Suzhou) Co., Ltd. is a high-tech enterprise integrating R & D, production and sales. The company relies on Germany's imported advanced technology and high-end equipment to achieve the development and production of high-efficiency compact finned tubes. The main products are high-efficiency energy-saving laser welding finned tubes and laser pad tubes.
At present, the transformation of boilers mainly refers to the transformation technology, that is, the use of solar thermal technology, combined with conventional coal-fired, fuel oil, gas, electricity, biogas and other traditional energy sources, new energy boilers to achieve energy saving and emission reduction transformation to achieve energy conservation Purpose, boiler flue gas emissions and pollution, due to the large amount of coal, oil, gas and other substances that produce huge amounts of sulfur dioxide and nitrogen oxides, these substances are the main cause of atmospheric pollution.
1. Boiler flue gas emissions and pollutants, due to the large amount of coal, oil, gas and other substances that produce huge sulfur dioxide and nitrogen oxides, these substances are the main cause of atmospheric pollution.
2. Cinder treatment, because the coal block cannot be fully burned, the cinder produced is the end of the industrial industry and can only be treated as waste.
3. Control of dust. In the winter heating cities in the north, it is often seen that a lot of dust floats from the high chimneys. Residents are afraid to open windows, which seriously affects the normal life and physical health of residents in nearby areas. As soon as winter in northern cities, air quality drops sharply, visibility is extremely low, and the number of haze phenomena increases dramatically, which not only affects the health of citizens but also causes traffic accidents.
4. Desulfurization treatment. The characteristics of China’s energy structure determine that controlling sulfur dioxide emissions from coal-fired boilers is the focus of China ’s control of sulfur dioxide pollution. In China, not only is the technology not mature enough, but also the investment is high and the operating costs are high. That said, it adds a lot of economic burden and environmental pressure.
5. Pressure on rising energy prices. In recent years, international oil prices have continued to rise, and as a result, the prices of energy resources such as natural gas and coal have risen. The price of coal has more than doubled in previous years, and the upward trend will continue into the future.
6. Insufficient safety, flammable and explosive, coal-fired boilers are different due to the quality of coal. Under the circumstances of temperature changes and insufficient fuel, it is easy to cause explosion accidents, which will bring harm to the production and life of the people.
7. Policy impact. Based on the above-mentioned reasons, the national policy mandates that the existing “two-high boilers” be eliminated or renovated, and small boilers be shut down and rebuilt, requiring the use of boilers that use clean energy as fuel.
Finned tubes are used for boiler heat exchange heat
1: The thickness of the base pipe can be 0.8-1.5 mm, and the thickness of the fins can be 0.3-1 mm. Compared with other processes, the material cost is greatly saved.
2: High penetration rate, can prevent gap corrosion, prolong service life, and reduce heat transfer heat resistance.
3: Break through the limitation of materials and use different materials for processing.
4: Easy re-processing, can be directly coiled and bent.
5: The welding heat-affected zone is small, and the metallographic changes are small, making small-diameter finned tube processing possible.
The materials of the heat exchange tube and the condensing tube should have excellent heat transfer performance, but also have good corrosion resistance, erosion resistance, abrasion resistance, and good strength and rigidity and plasticity, which is easy to manufacture.
