Title:
METHOD AND DEVICE FOR ESTIMATING OUTER SURFACE TEMPERATURE OF RADIATING PORTION COIL OF ETHYLENE GENERATING CRACKING FURNACE, AND ETHYLENE PRODUCING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/090327
Kind Code:
A1
Abstract:
This device for estimating the outer surface temperature of a radiating portion coil is provided in an ethylene generating cracking furnace (1) including a convection portion coil (8A) for preheating a hydrocarbon and steam, which are starting materials, the radiating portion coil (8B) which performs thermal cracking of the preheated hydrocarbon and steam, and a housing (2) accommodating the convection portion coil and the radiating portion coil, wherein the estimating device is equipped with: image capturing cameras (20) which capture images of an imaged region (60) of the radiating portion coil (8B); and an image analyzing device (22) which estimates the outer surface temperature of the radiating portion coil (8B) by processing output signals from the image capturing cameras (20).
