Device for estimating radiant coil surface temperature in furnaces
The patent US12044642B2 outlines a method and device for estimating the outer surface temperature of a radiant coil in a cracking furnace used for ethylene production. The method involves imaging a specific region of the radiant coil using an imaging camera, which can be a color video camera, a monochromatic video camera, or a 2-sensor camera. The output from the camera is processed by an image analyzer to estimate the outer surface temperature. The imaging can cover multiple radiant coils, and the image analyzer is capable of identifying hotspots and calculating their temperatures. Additionally, the estimated temperatures can be displayed alongside their positional information on a display device.
The device described in the patent includes an imaging camera and an image analyzer, both integrated into the cracking furnace system. The image analyzer may feature components for estimating maximum temperatures and identifying hotspots within the imaged region. Furthermore, the device can be equipped with horizontal and vertical drive units that allow the imaging camera to scan the radiant coil's field of view effectively. This scanning capability enhances the accuracy of temperature estimation by processing images captured during the movement of the camera. Overall, the invention aims to improve the monitoring and control of temperature in the radiant coils, which is critical for efficient ethylene production.
