Method and system for flame monitoring and control

A system for monitoring a flame of a burner of a lime kiln, comprising a video imaging device;

• and
• a processor configured to:
• image a video stream from the imaging device showing the burner end of the lime kiln to generate an imaged video stream;
• extract at least one image from the imaged video stream;
• determine, using a pretrained algorithm, from the at least one image at least one area of interest, wherein the at least one area of interest comprises a part of the at least one image showing an area comprising at least one characteristic portion of the flame and/or burner end;
• calculate the area of the at least one characteristic portion based on the pixels of the at least one area of interest;
• and
• determine at least one quantity of interest based on the calculated area of the at least one characteristic portion.
