Regarding oven drainage
Thread Content
When our company first started using the furnace with driving, the liquid level in the water seal tank was high, making it difficult to drain water and resulting in severe backfire. How should we proceed with direct drainage using a lockhopper? Do we need to operate the lockhopper manually and then open the upper, middle, and lower slag locking valves?
There are also requirements for direct discharge of the lock hoppers; it is necessary to extend the slag discharge pipe of these hoppers below the liquid level in the slag pool to create a water seal, which definitely requires modifications. If the level of the water seal tank is high, it can be discharged through the dual valves located after the black water discharge valve of the gasification furnace, via the pipes leading to the slag pool; or it can be directly discharged into the sedimentation tank (or true flash tank), and then pumped back to the slag pool using a low-pressure ash pump.
