How to stabilize the inlet of the conversion furnace
Thread Content
At our plant, the inlet temperature of the hydrogen production converter with a capacity of 10,000 cubic meters per hour fluctuates between 440 and 490 degrees, depending on the flow rate and pressure of the medium-pressure steam； Furnace negative pressure, oxygen content ； Analysis of aspects such as side burning temperature. There is no clear outcome yet; I request the expert’s guidance. Thank you.
1. Is there any fluctuation in the feed temperature? 2. Is the steam temperature high, with water present in it? 3. Is the system pressure unstable? 4. Is there a fault with the PSA, which is causing instability in the preceding processes? 5. Are there fluctuations in the composition of the hydrogen product?
We used 814 for PSA before and changed it to 824. It might be due to PSA. Thank you
It mainly stabilizes the flue gas temperature at the outlet of the radiant chamber of the conversion furnace. Generally, the feed to the conversion furnace is heated in the convection chamber; therefore, it is necessary to stabilize the flue gas temperature
As the original poster said, this is a very confusing phenomenon – only the temperature at the furnace inlet fluctuates, while all other parameters remain stable.:dizzy:
If what you said is all correct, consider the accuracy of the instrument.
