How to judge whether the air preheater of an industrial boiler is leaking?

2021-05-28

Due to low-temperature corrosion and wear of the air preheater, the preheater tube is easy to perforate, causing air to leak into the flue gas. In addition to the visual inspection of the preheater after the boiler is shut down, air leakage from the preheater can also be found when the boiler is running. The phenomenon of air leakage from the preheater is:

(1) The excess air coefficient after the preheater exceeds the normal standard.

(2) The blower current increases, and the air pressure at the inlet and outlet of the preheater decreases.

(3) The current of the induced draft fan increases because the load of the induced draft fan increases.

(4) When the air leakage is serious, the inlet baffle of the blower is fully opened, the air volume is still insufficient, and the boiler cannot reach the rated load.

(5) A large amount of cold air leaks into the flue gas, which reduces the exhaust gas temperature.
