Boiler "false water level" refers to the false water level for the time being. When the steam drum pressure fell sharply, because the pan of water saturation temperature drop to the corresponding pressure saturation temperature and release large amounts of heat to evaporate by oneself, so the pan of water inside the bubble increases, volume expansion, make the water level rise, form a false water level. Drum pressure jump, the corresponding saturation temperature increase. Part of the heat is used for heating water pot, reduce evaporation, a reduction in the boiler water bubbles, volume shrinkage, water level, the same form false water level. It will cause a lot of trouble for us, the formation of gas boiler manufacturers today is for everyone to summarize solutions for this problem. : the cause of the false water level of boiler
1. The boiler load mutation easily produce false water level.
2. The boiler fire easily produce false water level.
3. The boiler exit motions can produce false water level.
4. The boiler combustion instability easily produce false water level.
When there is false water boiler, first should correctly judge, often require operators monitoring of boiler load change, and the particular case is particular analysis, can take the right measures. Such as when the load increases with the water suddenly rises sharply, should be clear: from evaporation capacity is greater than for the balance of water quantity, the water level rise phenomenon is temporary, soon will fall and must not reduce the water, and should strengthen the combustion, back pressure, for water level began to drop, increase water immediately, to make it compatible with steam, returned to normal levels. Such as load increase amplitude is bigger, causes were also wide variations in water level, if don't control it could cause when filled with water at this time, should be appropriate to reduce water first, in order to avoid filled with water, at the same time enhanced combustion, back pressure; When the water level just have a downward trend, increase water immediately, otherwise, will cause the water level is too low. That is to say, should be accurate, timely treatment.
