The magnetic balls taken out of the converter have all sintered together, so they cannot be removed. It’s likely that the high pressure difference under normal conditions is also due to this reason. Who can tell me how to do it usually?
If pre-conversion or single conversion is carried out, control the composition of the raw gas generated through gasification
Of course there is. Isn’t this phenomenon occurring right now? Let’s see what the reason is
Does the composition of raw coal gas also have an impact? I still think it’s the temperature that has an effect. The temperature will be quite high later on.
The temperature is estimated to be over 490 degrees
What causes the sintering of ceramic balls? Is the catalyst of iron-based or cobalt-molybdenum-based?
In other words, without understanding the underlying reasons, one focuses on the issue of sintering; this is still caused by an excessively high reaction temperature. Generally, a separator, filter, heat exchanger, and pre-conversion furnace must be designed for medium-conversion furnaces. Could there be problems with the design of the heat exchanger or pre-conversion furnace? For example, excessive heat transfer capacity, concentrated hot spots in the newly installed catalyst leading to localized overheating, or too much catalyst in the pre-conversion furnace resulting in excessive heat generated from the reaction, which then reaches the inlet of the medium-conversion furnace and causes overheating there. If it’s a design issue, then solutions should be sought from a design perspective, such as implementing additional temperature regulation mechanisms.
Did the converter experience overheating during startup?
Is it sintered or stuck together? I’ve seen many cases of adhesion, but I’ve never seen any case of sintering. A change of around 500 degrees Celsius is common; it shouldn’t lead to sintering
What does adhesion look like? It’s like magnetic balls sticking together; it’s probably the catalyst powder that binds them together.
