The static slag breaker with four nozzles is clogged – how to diagnose and address it?
Thread Content
The static slag breaker with four nozzles originally had a grid that was too small; what indicators can be used to determine when slag lumps form? How to handle it? Unlike taphole blockage and syngas blockage, I believe that: 1. the pressure difference in the lockhopper will increase. 2. The pressure difference at the slag outlet is high during the slag collection phase, and the pressure in the lock hopper is also high. 3. In severe cases, the liquid level in the gasification furnace fluctuates greatly. Solution: 1. Increase the circulation volume of the quench water. 2. With the lock hopper operating two pumps, the slag collection time is reduced by 3. During shutdown, the grid is expanded to remove large debris. I would appreciate it if the teachers could offer some guidance...
The pressure difference in the lock hopper should decrease; the pressure within the lock hopper will drop as well. In severe cases, the pump used for circulating fluid in the lock hopper may run dry, resulting in a deterioration of the water quality in the system. Additionally, at this time the current of the slag skimmer should decrease, and the amount of slag removed by the scraper should also decrease. The outlet flow rate of the lockhopper circulation pump can be increased; it is advisable to enable backwashing, and high-pressure nitrogen should be installed at the bottom of the gasification furnace.
The outlet pipe of the lockhopper pump is located below the static slag breaker, and increasing the flow rate of water used for flushing the lockhopper has no effect on preventing blockages. The correct procedure is to close valve 8 of the lock hopper and open valve 7 of the lock hopper to perform repeated pressurization. High-pressure nitrogen should be used as little as possible. Parking rectification is not handled properly.
If a static slag remover is used, and a valve in the lock-hopper system is replaced, slag may not be discharged for 2 to 3 hours; could this lead to an accumulation of too much slag at the bottom of the furnace, causing a blockage?
But why use a static slag remover? What role does a static slag remover play when a regular slag remover is already available? I think it’s not necessary to use a static slag remover as long as the defoaming strips are properly in place
