Guide: Causes and treatment methods of boiler full of water phenomenon 1. Boiler full of water phenomenon performance: Boiler water level gauge can not see the water level, the color of the water level gauge glass tube (plate) is dark; the boiler feed water flow is abnormally greater than the steam flow; the boiler height The water level alarm generates a high water level alarm signal; a large amount of water is stored in the sub-cylinder of the boiler, and the steam trap acts violently; the boiler superheated steam temperature
The reason and treatment method of boiler full of water
1. The boiler is full of water. Performance:
The boiler water level gauge cannot see the water level, and the color inside the glass tube (plate) of the water level gauge is dark;
The boiler feed water flow rate is abnormally greater than the steam flow rate;
The boiler high and low water level alarm generates a high water level alarm signal;
There is a large amount of water in the sub-cylinder of the boiler, and the steam trap acts violently;
The boiler superheated steam temperature has dropped significantly;
Boiler two-color water level gauge shows all water phase indication colors;
When the boiler is full of water, the steam will carry a lot of water and the salt content will increase. The sound of water hammer occurs in the steam pipe, and steam drips from the connecting flange;
2. The reason why the boiler is full of water
(1) The boiler fireman ignores the monitoring of the water level;
(2) The valve for automatic adjustment of boiler feed water is abnormal, causing a large amount of water to the boiler;
(3) The steam and water connecting pipes of the boiler water level gauge are blocked and the drain cock is leaking, resulting in incorrect water level indication and incorrect operation.
3, the boiler full water treatment method:
(1) Flush and check the water level of each water level meter to determine the authenticity of the water level indication. If you can still see the water level, it means that it is slightly full; if you can't see the water level, you should call the "water" method to determine whether it is slightly full or severely full. The method of "calling water" for full water is: ①rinse the water level gauge once in the general order; ②close the cock on the water connecting pipe of the water level gauge after flushing; ③open the purge cock before opening. If you see a drop in the water level from the top of the glass tube (plate), it can be concluded that it is slightly full. If there is no drop in the water level and the entire glass tube (plate) only sees water flowing downwards, it can be concluded that it is seriously full. water.
(2) If the boiler is slightly full of water. The following treatment methods should be adopted: ①Adjust the combustion intensity to weaken the combustion; ②Stop the water supply and open the drain valve to drain; ③Until the water level is normal, close all the drain valves before returning to normal operation.
(3) If the boiler is seriously full of water, the following treatment methods should be adopted: ①The boiler should be shut down according to the emergency shutdown procedure; ②Stop the water supply and strengthen the drain valve to drain; ③Open the steam main pipe and the water delivery valve with superheater , Carry out rapid water delivery; ④ After the water level is normal, close the sewage valve and all drain valves, and then resume the ignition operation.
