【Q&A Question 096】July 25, 2016: Methods for dealing with liquid in the steam generator. The answer key can be seen after responding; scoring is based on providing the key points. Methods for dealing with liquid accumulation in the steam generator: 1. First, disconnect the heat source from the steam generator to allow it to cool down. 2 Open the steam vent valve to release the steam from the pipeline system. After the temperature of the Class 3 steam generator drops, add water to the drum until the normal liquid level is reached, and then restart it following the normal startup procedure. 4. When the liquid level is low, never add water to the drum immediately to avoid accidents caused by boiling over.
Answer: (1) First, disconnect the heat source from the steam generator to allow it to cool down； (2) Open the steam vent valve to release the steam from the pipeline network ； (3) Wait until the temperature of the steam generator drops, then add water to the drum to reach the normal liquid level, and restart it following the normal startup procedure ； (4) When the liquid level is low, never add water to the drum immediately to avoid accidents caused by boiling over
Remove it promptly; divert the steam to venting – never add water directly

Treatment method: 1 First, disconnect the heat source from the steam generator to allow it to cool down. 2 Open the steam vent valve to release the steam from the pipeline system. After the temperature of the Class 3 steam generator drops, add water to the drum until the normal liquid level is reached, and then restart it following the normal startup procedure. 4. When the liquid level is low, never add water to the drum immediately to avoid accidents caused by boiling over.
Remove the heat source, cool down, and then add water
Stop the heat source, slowly cool down to below the boiling point, add water, adjust the liquid level to the normal level, then slowly restart the heat source to increase temperature and pressure and connect it to the grid
Open the desalinated water inlet valve wide, and open the hot material inlet valve slightly
Different measures are taken depending on the liquid level: 1. If a low-liquid-level alarm is triggered, emergency shutdown procedures are initiated after confirming that there is no liquid left. 2. When the liquid level is low but still displayed, reduce the load on the device and increase the water inflow rate
Replenish fluids promptly or cut off the heat source to prevent dry burning
