Title:
SYSTEM AND METHOD FOR ONLINE DETECTION OF HOT INCLUSIONS, SUCH AS COKE PARTICLES, IN MINERAL WOOL, ESPECIALLY DURING PRODUCTION
Document Type and Number:
WIPO Patent Application WO/2011/076888
Kind Code:
A3
Abstract:
The invention relates to a system for detection of hot enclosures, such as hot coke particles, in mineral wool, particularly during production of mineral wool in a production facility, comprising: at least one microwave scanner oriented on the mineral wool to supply enclosure detection signals based on a response from the mineral wool web and/or possible enclosures to generated microwaves; at least one radiometric sensor oriented on the mineral wool to supply temperature detection signals from temperature dependent radiation originating from the mineral wool and/or the enclosures; and at least one processor arranged for processing the enclosure detection signals from the microwave scanner to determine if an enclosure is present in the mineral wool, and for processing the temperature detection signals from the radiometric sensor to determine the temperature of at least an enclosure determined to be present on the basis of the enclosure detection signals.
