True or False: Water shortage incidents and water overfilling incidents do not necessarily cause damage to the pressure-bearing components of the boiler ( ). Thank you for your support; correct answers earn +8 points, while incorrect answers result in a loss of 45 points plus +3 points
Water shortage accidents and water overfilling accidents do not necessarily cause damage to the pressure-bearing components of the boiler (False)
Xiaopang is making rapid progress! Reply to see what the answer is. Water shortage accidents and water overfilling accidents do not necessarily cause damage to the pressure-bearing components of the boiler. At the beginning of operation, when the load is very low and the temperature has not yet risen, especially when the tank is full with water and there is no pressure difference.
Little Fat Bro, what you’re hiding isn’t the answer!
Water shortage incidents and water overfilling incidents do not necessarily cause damage to the pressure-bearing components of the boiler (False)
Water shortage accidents and water overfilling accidents do not necessarily cause damage to the pressure-bearing components of the boiler (X)
Error----------------------------------------------
Error: Water shortage incident: The water level in the gauge is below the minimum safe level, there is an incorrect reading of the water level or no water level can be seen; the temperature of the superheated steam and the exhaust gas rises abnormally; the pipes and valves related to the water level gauge are blocked ； Failures in water supply equipment and pipelines ； Leakage in the drain valve and release valve ； Tube explosion, full-water accident: The water level indicated by the gauge is higher than the maximum safe level, there is an incorrect reading of the water level or no water level can be seen; the temperature of the superheated steam drops, water hammer occurs inside the superheater, and the gauge loses its functionality ； The water supply automatic regulator has failed
Water shortage accidents and water overfilling accidents do not necessarily cause damage to the pressure-bearing components of the boiler (correct)
Water shortage accidents and water overfilling accidents do not necessarily cause damage to the pressure-bearing components of the boiler (correct)
Water shortage accidents and water overfilling accidents do not necessarily cause damage to the pressure-bearing components of the boiler (X)
