Continuous duct burner monitoring and flame profiling

The Valmet Visible Imaging System lite (Valmet VISLite) is a rugged, air-cooled, HD visible camera designed for comprehensive observation and analysis when firing duct burners. The advanced image processing software enables automating flame identification and flame segmentation to generate automated warnings and alarms to operators.

Duct burner monitoring for maximum availability

The Valmet VISLite provides unparalleled image quality from start up to full load conditions. It is particularly well suited for observing flame applications.

“Valmet recently provided their proven technology to a HRSG in the state of Georgia. Using the Valmet Visible Imaging System Lite, the operators will have “eyes” on their duct burner flame. Ultimately this will lead to, with the addition of Valmet’s software, first of its kind control of duct burners, which is a big step to more precision in operation of an HRSG.” – Steven Mathis, President, Entech Products Corp.

Real-time information on flame profile

The advanced image processing software detects the flame and provides measurements which include flame width, height, and size. Based on the flame data and flame edge location, the software can generate alarms. Additionally, the software also allows to segment the flame, define unique combustion zones (up to 49 zones), and flame center of mass coordinates.

The system includes automated time-lapse reporting which contain combustion and flame data points plotted against the raw image, processed image and combustion zones that were captured during the day.
