Converter conversion rate
Thread Content
How can one tell whether the rise in converter temperature is due to peroxide auto-ignition or proper air supply?
From the question you asked, it’s clear you’re a beginner. Normally, the catalyst bed has a relatively stable temperature rise; generally, it is 70–100°C in the first reactor and 10–30°C in the second reactor. If the temperature rise exceeds the aforementioned range by a significant amount, it is necessary to consider whether there is a problem of spontaneous combustion in the bed.
Under normal conditions, the temperature rise rate of a converter is not fast; however, if peroxide auto-ignition occurs, the temperature rises rapidly due to the highly exothermic nature of the combustion, and it usually exceeds 400 degrees Celsius.
