Judgment and treatment of water shortage and full water accident in steam boiler

Steam boiler water shortage judgment. The simplest and most direct judgment is to see if the current water level is lower than the minimum safety line, and even the water level is not found. The glass plate of the water level gauge turns to white, and the steam boiler with the alarm is below the safety line when the water level An alarm signal will be issued to indicate that, besides the information provided by these steam boilers, it is also necessary to pay attention. Below the safe water level, the superheater temperature of the steam boiler will suddenly rise, which is much larger than the normal export temperature value. The steam flow at this time will be greater than the flow to whom. Steam boilers can smell a burnt smell when water is scarce, and the water-cooled helium tube turns red. This time, special attention must be paid to the explosion. When there is a shortage of water in a steam boiler, it is necessary to calmly judge the severity of water shortages. If it is a slight shortage of boiler water, it is not necessary to panic, reduce the amount of fuel input, reduce the amount of blast, and reduce the speed of water supply to the boiler.

Steam boiler full of water to judge. Also look at the water level line first to see if it exceeds the maximum value or if the water level line is no longer visible. When there is an alarm device, an alert will be given. The difference between the water level and the lack of water is that the glass plate of the water level gauge will darken, and it will be divided into cylinders. A large amount of stagnant water appeared, the steam temperature did not increase, but dropped significantly, and the steam trap oscillated. When there is a serious flood, the salt content of steam increases, and the sound of water hammer appears in the steam boiler's pipeline. If the situation is full of water, emergency shutdown to avoid the risk of explosion, other mild water can be taken to stop the water, open the sewage valve to the normal water level can be.
