A Method for Measuring Tube Metal Temperature of Ethylene Cracking Furnace Tubes Based on Machine Learning and Neural Network

Abstract

Temperature monitoring of the tube metal temperature (TMT) of cracking furnace tubes is essential to the normal production of ethylene. However, the existing infrared temperature measurement technology has certain defects in the accuracy of temperature measurement, the accuracy of temperature discrimination of overlapping furnace tubes and the technical cost. In view of this, this paper proposes a novel measurement and processing method. In this method, our team developed a new generation of intelligent temperature measurement devices for measuring TMT, and proposed an intelligent temperature processing algorithm based on machine learning and neural network running on this intelligent temperature measurement devices. This method not only realizes the automatic measurement of TMT, reduces the workload of operators, but also improves the accuracy of measuring TMT and the accuracy of overlapping tube identification. In addition, this method also reduces the technical cost of TMT measurement to some extent. Finally, by comparing the TMT data measured by different methods, it is proved that the proposed method has better performance level than other methods.

Intelligent Coking Diagnosis Method of Ethylene Cracking Furnace Tube with Data Mining Techniques

“…Peng et al developed a noncontact infrared temperature-measuring robot for the furnace tube outer wall. A guide rail was installed outside the fire viewing port so that the temperature-measuring robot automatically slid on the guide rail to measure the temperature and achieve multi-point temperature measurement on the furnace tube outer wall [11,12].…”

A ridge estimation-sequence quadratic programming constraint optimization algorithm for data processing in multi-spectral thermometry

“…Multi-spectral thermometry is a typical non-contact temperature measurement technology. This technology has been widely used in the field of high temperature measurement due to its no upper measurement limit in theory and rapid response [1][2][3][4][5][6][7]. The data processing is the key of multi-spectral thermometry, and the core of it is to solve a system of equations containing N equations.…”
