What are the treatment measures of boiler economizer tube burst?

18 Mar 2022

How to correctly handle the tube burst of boiler economizer and find out the reason for the tube burst is very important:

1. The water quality is not up to standard, and the oxygen contained in the water decomposes and corrodes the pipe wall when the temperature rises.

2. If the feed water temperature and exhaust gas temperature are too low, the inner and outer walls of the economizer tube will be corroded by acid, or the tube wall will be thinned due to the abrasion of fly ash.

3. The tube is blocked by sundries, causing overheating.

4. The material is not good, and there are defects in the process of manufacturing, installation and maintenance.

5. Economizer is short of water during shutdown or startup.

 

Treatment measures of boiler economizer tube burst:

1. In case of slight rupture of the economizer, which can maintain the operation of the boiler, and the crack can't expand rapidly, the boiler economizer tube burst should be operated at reduced load, and the standby boiler should be started immediately. After the standby boiler is put into normal operation, it should be treated as normal shutdown.

2. In case of the serious rupture of the economizer, insufficient water supply to the circulating water pump or rapid pressure drop, the boiler economizer tube burst should be urgently shut down. At this time, the outlet flow of circulating water should be reduced to keep the boiler water pressure, keep the induced draft fan running, and stop the boiler after removing the flue gas and steam in the boiler.
