How to deal with a blocked outlet pipe for the process gas in a gasification furnace
Thread Content
The outlet pipe of the process gas in the gasification furnace is blocked, resulting in a gradual decrease in the flow rate of the quench water. Attempting to clean it with high-pressure water or by tapping on the outlet pipe has not been effective. I earnestly request advice from experts!
Could you open the vent valve a bit to give it a try?
““The outlet pipe of the gasifier process gas is blocked, and the flow rate of the quench water is gradually decreasing” – is there a significant relationship between these two? How could it get clogged here? Even with a high level of fine ash, it shouldn’t cause clogging, right? Each one is equipped with a small stream of high-pressure water at the process gas outlet to prevent dust accumulation from blocking the pipes.
Reply 3# It is possible that the blockage of the process gas outlet pipe in the GSP gasifier has led to a decrease in the flow rate of the quench water; this is because of the high resistance inside the gasifier, which limits the amount of quench water available. I think the process gas outlet pipe of the stove in the original poster’s home is already quite blocked, which leads to a decreasing load and an increasing pressure difference in the lock hopper.
If the outlet pipe of the process gas is severely blocked, the plant must be shut down for maintenance; after restart, the outlet of the process gas should be regularly cleaned using high-pressure gray water to prevent dust accumulation from blocking the pipes.
