Title:
DBSCAN-BASED OUTER SURFACE TEMPERATURE MEASUREMENT METHOD FOR CRACKING FURNACE TUBE
Document Type and Number:
WIPO Patent Application WO/2020/253485
Kind Code:
A1
Abstract:
A DBSCAN-based outer surface temperature measurement method and system for a cracking furnace tube, and a computer readable storage medium, relating to the field of industrial ethylene temperature measurement devices. The method comprises: measuring a plurality of continuous temperatures of the outer surface temperature of a cracking furnace tube to obtain a temperature data set thereof; and then calculating to obtain a cluster of the outer surface temperature of the cracking furnace tube according to a DBSCAN algorithm; finally, calculating the average value of the temperature in the cluster according to the cluster as the outer surface temperature measurement result of the cracking furnace tube. The method significantly improves the accuracy and theoreticality of the calculation of the outer surface temperature of the furnace tube, and provides a safety guarantee for the ethylene cracking production.
