The number of furnace tubes in each of the four furnaces in the reformation furnace is different
Thread Content
Why does the third furnace in the four-in-one furnace have the highest number of tubes, and why are these tubes thinner than those in the other furnaces?
The second one is the highest, right? Did I look at it the wrong way?
In a four-in-one setup, the second furnace is usually the largest, with the most furnace tubes
The second one is the highest, because the temperature drop upon reversal is the greatest. The reaction that proceeds in the reverse direction absorbs the most heat.
You’re going in the wrong direction; we have 24 burners in Furnace 2.
Our second one is the highest, because the temperature drop is the greatest in that case
Reactor No. 1 and Reactor No. 2 have the same number of tubes. The difference lies in the burner load.
Boiler No. 2 is the largest, with the greatest temperature drop in reverse flow
In the case of one-phase and three-phase reactions, the entry of cold hydrogen requires more heat, and this is most evident during startup and shutdown. The 2.3 reactors can even go out of operation at the beginning of operation or shutdown, with little impact
The greater the temperature drop, the more heat needs to be supplied, mainly because there are strong endothermic reactions with few exothermic reactions
