Abstract:

The accuracy of coil outlet temperature (COT) measurement of ethylene cracking furnace is closely related to the yield of product and the operation cycle of cracking furnace. This paper discusses the error causes of three traditional COT measuring methods currently used based on practical cases, and summarizes their advantages and disadvantages, providing suggestions for engineering design and actual production.

Key words: cracking furnace, coil outlet temperature, temperature measuring methods, improvement method, error analysis
