The energy-saving and environmentally friendly characteristics of natural gas boilers make them very popular in the boiler market. Today we will popularize the water level control of natural gas boilers.
The structure of natural gas boilers is relatively simple, so when the natural gas boiler is running, it needs to be kept at a normal water level. Once the water level is too low, it will easily cause a water shortage accident, and it will also easily lead to an abnormal situation of a dry pot, and then the newspaper boiler tube will be damaged. In severe cases, it will also cause the boiler to explode, but if the water level is too high, it will also be dangerous.
If the water level is too high, the steam will carry a lot of water when it is discharged from the boiler, which will deteriorate the quality of the steam, and it will gradually deteriorate. In severe cases, it will also cause a full water accident. Therefore, the water level of the boiler must be strictly controlled to keep the water level fluctuating within the specified range.
In summary, there is a dynamic balance between the evaporation amount and the water supply of the boiler. At this time, the water level of the boiler will fluctuate to a certain extent, which is within the normal range. If the evaporation amount is greater than the water supply, the water level will decrease, otherwise the water level will increase. Only when the two are equal, the water level can remain unchanged.
The main reasons affecting normal water level fluctuations are changes in boiler load or combustion conditions, as well as air leakage, water leakage, sewage discharge, etc. If the boiler load decreases or the combustion weakens, the evaporation in the boiler will decrease. If the water supply remains unchanged, the water level will rise. The water supply must be adjusted in time to adapt to the change in evaporation.
