What Are The Common Faults Of Economizer Pipes

Common Faults of Economizer Tubes Include:

Pipe corrosion: Since the flue gas contains corrosive media, such as sulfides, nitrogen compounds, etc., the economizer pipes are easily corroded, causing problems such as thinning of the pipe wall and perforation.
Dust accumulation and blockage: During the operation of the economizer tube, ash in the flue gas is easy to deposit on the tube wall, forming dust accumulation, which affects the heat transfer effect, and in severe cases, may lead to pipeline blockage.
Abrasion: The particulate matter entrained in the flue gas wears the economizer tube during the high-speed flow process, causing the tube to wear and become thinner, which can easily lead to leakage or tube explosion and other failures.
Vibration and displacement: The economizer pipe may be affected by vibration and displacement during operation, leading to problems such as loose connection parts or cracked welds.
Temperature that is too high or too low: During the operation of the economizer tube, the temperature that is too high or too low will have adverse effects on it. Too high a temperature may cause overheating, deformation or oxidative corrosion of the pipe; too low a temperature may cause the pipe to produce condensation water or freeze and crack.
For these common faults, regular maintenance and inspections should be carried out, and problems should be discovered and dealt with in a timely manner to ensure the normal operation and service life of the economizer tube.
