Is the pressure difference at the slag outlet of the spaceflight gasification furnace high? What is the reason?

The pressure difference at the slag outlet of the spaceflight gasification furnace is 25 KPA – what could be the reason?
The slag outlet becomes clogged, reducing the cross-sectional area of the gas flow channel and resulting in an increased pressure difference at the slag outlet
If the pressure difference at the slag outlet is high, there are several possible reasons: 1. The slag outlet is blocked; it’s possible to melt the slag by increasing the temperature under reduced load (this involves some risk, as improper temperature control could cause the slag on the walls to melt, forcing a shutdown of the system). 2. There is slag accumulation in the downcomer, which also requires a shutdown for treatment. 3. The syngas outlet pipeline is blocked (this depends on where the pressure difference is being measured); it’s recommended to shut down the system for handling this issue
