On a steam raising boiler there are three clear applications for level monitoring devices:
1) Level control - To ensure that the right amount of water is added to the boiler at the right time.
As their name implies, hot water boilers operate by being completely filled with hot water. On the other hand, steam boilers are usually only filled approximately 3/4th of the way full, while the top quarter is reserved for steam.
Although most people know their boiler will not last forever, many people treat it as it should. On average, your industrial boiler should last you anywhere from 20 to 25 years without any trouble. If you’re around year 15, you may be able to retrofit your boiler to update it with newer technology.
The oil-fired boiler refers to the boiler fueled by oil, including the diesel, waste oil and other fuel oil. The oil consumption of the oil-fired boiler affects the economic operation of the boiler.
The safety valve of the boiler refers to the valve on the top of the boiler near the boiler control room. The function of the safety valve is to be opened automatically to exhaust the steam and restore the pressure when the boiler pressure exceeds the specified valve, so as to ensure the safety of boiler pressure-bearing components and steam turbines.
According to the power of water or steam circulation, boilers can be divided into natural circulation boilers, forced circulation boilers, once-through boilers and combined circulation boilers.
The quality of boiler feedwater is an important determinant of safe boiler operations and it should be monitored to maintain the quality within safe working limits. Boiler feedwater is treated to protect the boiler from two basic problems: the buildup of solid deposits on the interior or water side of the tubes, and corrosion.
In the boiler operation,the flue gas discharged from the flue gas duct has a certain temperature. However, the abnormal increase of flue gas temperature in boiler's flue gas duct is usually accompanied with other abnormal phenomena. In this regard, corresponding measures should be taken for adjustment based on the reason analysis.
