Valmet introduces a new lime kiln flame profile application for pulp mills

Valmet introduces a new flame profiling application that enables real-time flame detection and monitoring in a pulp mill’s lime kiln environments. At the same time, the Valmet Furnace Imaging System, IR is updated with new optics and a port rodder, improving the overall Valmet Boiler Diagnostics Systems offering.

“We are constantly developing our camera-based diagnostics offering for both pulp and energy customers. The new flame profile application can be used to control the hot end temperatures of a lime kiln to optimize the residual carbonite in lime. In the end it helps to decrease the energy consumption of the kiln,” says Matti Selkälä, Business Manager, Pulp and Energy Analyzers, Automation Systems business line, Valmet.

Real-time information on lime kiln flame temperature and profile

The new flame profiling software is an add-on application for Valmet Visible Thermal Imaging System. The software detects the flame, measures its relative size and provides distance measurements from the end of the detected flame to user defined markers. These features help to optimize fuel combustion, increase availability and reduce emissions. At the same time, they improve safety by offering users a better understanding of the current conditions.

The software is used in conjunction with the Valmet Visible Thermal Imaging System, an advanced solution with high-definition imaging and temperature analysis, ideally suited for lime kiln applications. The system is engineered for durability and longevity and delivers visual and thermal analysis for optimizing fuel combustion and lime quality in lime kilns.

New mechanics improve availability and performance

Additionally, Valmet Furnace Imaging System, IR has been upgraded with new optics and port rodder technology for enhanced image quality and more accurate metrics. The infrared camera system provides online visual analysis to see through flue gas and fly ash. It enables a comprehensive observation and analysis at full load which reduces risks and improves productivity. The new port rodder makes cleaning of the camera more effective, improving availability and operational safety.
