Flue gas waste heat (RTO) technology is a commonly used energy method in industrial production processes. It is able to effectively control the high temperature heat contained in the flue gas emitted into the atmosphere.
Energy utilization not only reduces energy waste, reduces production costs, but also plays a positive role in environmental protection.
However, due to the different composition and characteristics of industrial flue gases, there may be a variety of corrosive substances in the flue gases, which puts forward higher requirements for the corrosion resistance of RTO equipment. After all, the long-term stable operation of the equipment needs to face the harsh operating environment and the erosion of corrosive substances such as strong acids and alkalis, and only with excellent corrosion resistance can the life and efficiency of the equipment be guaranteed.
In order to solve this problem, current research and practice have shown that the use of corrosion-resistant materials and corresponding protective measures is crucial. The following will introduce two common RTO supporting flue gas waste heat** corrosion resistance methods.
The first method is to build an RTO device using corrosion-resistant materials. For example, the use of higher grades of stainless steel, such as 316L stainless steel, can provide better corrosion resistance. In addition, the internal and external surfaces of the equipment can be coated with ceramic coatings or poly with high corrosion resistance.
Composite coating to provide a stronger protective layer that protects the inside of the device from corrosive substances. These methods can effectively extend the service life of equipment and reduce maintenance and replacement costs.
The second method is to create flue gas passages in RTO equipment using corrosion-resistant special materials. The flue gas passage is the main passage through which the flue gas passes, and it is also the place where the corrosion of corrosive substances to the equipment is most serious. Therefore, the use of corrosion-resistant special materials, such as high aluminosilicate ceramics, in the flue gas passage can effectively reduce the corrosion degree of the equipment. This material has good corrosion resistance and high temperature performance, and can operate stably for a long time in harsh environments, which improves the reliability and stability of the equipment.
In addition to the above methods, it is also necessary to regularly overhaul and maintain the RTO equipment and replace the severely corroded parts in a timely manner. By checking the operation of the equipment, timely finding and repairing the problems that may lead to corrosion, the service life of the equipment can be improved, and the maintenance cycle of the equipment can be prolonged.
To sum up, the corrosion resistance of the waste heat of the flue gas supporting RTO is a key issue. By using corrosion-resistant materials that meet the requirements and corresponding protective measures, the equipment can be ensured to operate stably in harsh environments. In addition, regular overhaul, maintenance and replacement work are also important links to maintain the long life and efficient operation of equipment. Only on the basis of ensuring that the equipment has excellent corrosion resistance, RTO supporting flue gas waste heat technology can better play its advantages of energy saving and environmental protection, and provide reliable support for industrial production.
