The danger is mainly due to a large amount of water in the steam, which may cause the water to impact the steam pipeline, reduce the quality of the steam, affect the normal supply in steam and reduce the thermal efficiency of the boiler. . In severe cases, the superheater tube will build up and damage the steam equipment.
The boiler full of water accident is divided into two types: the boiler is slightly full of water and the boiler is seriously full of water.
1. If the water level exceeds the maximum permitted water level, but is lower than the upper visible edge of the water level, or the water level exceeds the upper visible edge of the water level, it may be quickly drained after opening the water level meter drain valve. When the water level is about to drop, the boiler is said to be slightly full of water.
2. If the water level exceedsthe visible edge of the upper part of the water level and the water level does not drop in the water level after opening the water level tap, it is said that the boiler is seriously full of water water.
Detailed information
Preventive measures
1. Strengthen technical safety training for boiler workers and improve their operational level and job responsibilities. .
2. Flush the water level frequently to ensure that the water level indicated by the water level is correct.
3. Strengthen the maintenance and management of automatic water supply devices and water level alarm systems, check and adjust them regularly to eliminate hidden dangers.
4. Install the water level meter correctly and strengthen inspection during operation to avoid false water levels.

How to deal with a boiler full of water
a) The drum water level gauge indicates a level above +50mm < /p>
b) The audible and visual alarm sounds a “high water level” alarm and the alarm bell rings
c) The feed water flow is abnormally greater than that of steam; Speed ;
d) When seriously filled with water, the main steam temperature drops significantly and steam escapes from the steam pipe flange.
The method for dealing with a steam boiler full of water is to immediately stop the water supply and then lower the water level by discharging the waste water. In the event of water hammer, draining by bypass of the sub-cylinders must be carried out. During wastewater discharge operations, someone must monitor each water level gauge to prevent false water levels. This type of operation is most likely to cause falsewater levels.
