Title:
SLAG AMOUNT ESTIMATION METHOD
Document Type and Number:
WIPO Patent Application WO/2024/057758
Kind Code:
A1
Abstract:
This slag amount estimation method includes: capturing, with a single imaging device, an image of a slag flow which flows out from an outlet of a refining vessel and expands in width in the upstream rather than in the downstream; finding the width of the slag flow from the captured image and then finding a volume flow rate or mass flow rate; and estimating an amount of slag on the basis of the found volume flow rate or mass flow rate.
