What is the impact of frequency conversion on a coking radiation pump’s operation?
Thread Content
Can the use of a variable-frequency drive on a coking radiation pump lead to a decrease in the flow rate of oil inside the furnace tubes, thereby causing coking? What are the requirements for other operations?
Aren’t your radiation pumps variable-frequency? It is a variable-frequency pump by design, which is easy to operate, energy-efficient, and has never experienced the issues mentioned by LZ. Generally, coking occurs due to feed interruption or a significant reduction in feed, as well as interruptions in water injection, which lead to overheating.
After up-conversion, the speed can be easily controlled according to the required outlet flow rate to save energy; however, it should be noted that a decrease in speed leads to a reduction in the pump’s outlet pressure. As a result, the flow rate and thus the flow velocity within the furnace tube also decrease, so it is necessary to adjust the amount of water (or gas) supplied.
Agree with what was said on the 2nd floor – there won’t be any impact, and no adjustments are needed!
