What is the low-level gauge on the steam drum of a boiler? What is its working principle and internal structure?
Reply to 1# quanyu502: To prevent the steam drum from experiencing a dry condition, it should be used in conjunction with a level gauge to ensure that the water level in the steam drum remains at a reasonable level. If the water level is too low, it indicates an abnormality in the boiler feedwater, or a sudden increase in the boiler load, which results in an excessive flow rate in the rising pipe and a decrease in the water level in the drum.
