Normal operating condition of the quench water filter
Thread Content
In normal operation, should the quench water filters be used one at a time with one as a backup, or should they all be in use simultaneously?
If the filter becomes clogged and reduces the flow rate of the quench water, switching to or activating a backup filter can restore stable production. Before the standby quench water filter is put into use, both the inlet and outlet valves must be closed. No matter which valve is opened, a dead zone will form inside the backup filter, and it will get clogged as sediment accumulates, rendering it completely ineffective as a backup. During the operation of the gasifier, it is absolutely forbidden to stop the quench water; even a brief interruption in its supply can lead to serious consequences such as damage to the quenching ring. Therefore, backup equipment must be installed for safety reasons.
When there is a blockage, the flow rate decreases; how to deal with it
