How to prevent heat pipe corrosion in the air preheater of a heating furnace?
Thread Content
The image below shows the heat pipe corrosion and soot accumulation in the air preheater of a petrochemical plant’s heater, which severely affects the operation of the preheater. Are there any good ways to improve it?
These types of heat exchangers have the advantages of small size and high heat exchange efficiency. For problems like those in the figure, it is necessary to modify the physical and chemical properties of the heat transfer medium so that they meet the requirements of the heat exchanger’s operating conditions. For example, use heat exchangers made of materials with a larger volume that are easy to clean and resistant to corrosion. Add air purification system equipment, for reference only.
