Boiler water level control
Thread Content
Could everyone help analyze this: There is a 40-ton gas boiler that shuts down due to a fault under high load, which causes a sudden drop in the pressure in the pipeline network. As a result, the water level in the boiler drops sharply, falling below a critical level such that it becomes impossible to add water. How can the boiler’s water level be controlled in such a situation? Prevent it from dropping below an extremely low level, which could affect operation.
Was the shutdown caused by a failure and explosion in the soda water system? Theoretically, if the water level is too low, it is not allowed to be raised immediately. Is it because it can’t be rehydrated?
Sure, it depends on what the fault is; we need to fix the issue first
In fact, it should be that when external users reduce their load, the pressure in the pipeline network rises suddenly, which causes the boiler water level to drop sharply; subsequently, due to the protective shutdown of the boiler, the pressure in the pipeline network drops abruptly. If that’s the case, it’s probably a common feature of gas boilers; you just need to do the same as what others do!
As long as the temperature on the monitoring gauge in the control room does not rise sharply, it is still possible to increase the water supply; if the temperature on the gauge rises sharply, then there is nothing to do but shut down the furnace
