The boiler water level gauge is a detection instrument that shows the water level of the boiler, and it is one of the important safety accessories of the steam boiler.
Boiler parameters are the main indicators of boiler performance, including boiler capacity, steam pressure, steam temperature, feed water temperature, etc. Boiler capacity can be expressed by rated evaporation or maximum continuous evaporation. Rated evaporation is the amount of steam continuously produced per unit time under the specified outlet pressure, temperature and efficiency. The maximum continuous evaporation is the maximum amount of steam that can be continuously produced per unit time under the specified outlet pressure and temperature.
At the same water temperature, the larger the excess amount of oxygen scavenger in water, the faster and more complete the chemical reaction. Under the same dosage, the higher the water temperature, the better the deoxidization effect. Under the same deoxidization effect, the higher the water temperature, the smaller the dosage.
Industrial boiler is special equipment, the particularity and complexity determine that safety is its fundamental. In fact, the so-called safety door refers to the boiler explosion-proof door.
As a kind of special equipment, the safe operation of industrial boilers is the key point that every enterprise may pay attention to. Today, let’s talk about the normal water level in boiler operation.
During the normal operation, the steam drum water level maintains 0mm, and the allowable fluctuation range is ±30mm, with the maximum not exceeding ±50mm.
With the continuous development of economy, as the main heat energy equipment, industrial boilers are widely used. This article discusses the calculation standard of boiler feedwater enthalpy value.
Manually close the fuel supply valve, stop the combustion, purge after the program enters, until the end of the purge, stop the program such as burning heavy oil, and enter the line sweeping stage before stopping the combustion, and purge with steam or light oil pipe; Generally, steam purging is used when stopping for a long time.
Generally, it is required that the water temperature shall be reduced to 80℃ to drain the water in the boiler. This is because if the water temperature is high, the temperature in the furnace is still very high, and the metal of the furnace wall and heating surface will still accumulate some heat. After the water is released, there is no working medium in the water wall to cool, which makes the wall temperature rise and the temperature rise is uneven, which is not conducive to the safety of the water wall.
