Due to the coal supply forms and cost-reduction requirements, many thermal power plants use coal types that differ from the original design specifications or burn open-pit coal, which is more prone to slagging and contamination. To mitigate the risks of boiler contamination and coking, thermal power plants employ methods such as coal blending, boiler heating surface soot blowing, and spraying nanophase materials on furnace heating surfaces. However, coking and contamination remain significant technical challenges that threaten the safe operation of boilers.

Mobile Infrared Camera System for Boiler Tube and Furnace Inspection. It utilizes high-performance multi-spectral technology and applies a specialized filtering algorithm to process the images. The system‘s unique high-temperature-resistant design allows for continuous operation without requiring boiler shutdowns, enabling real-time monitoring of the coking condition on the water-cooled walls and heater surfaces. This system helps coal-fired power plants operate more efficiently, extract more energy from coal, and increase overall productivity.

This type of boiler coking detector is designed to operate under the harshest conditions, particularly for boilers or kilns exposed to heavy smoke and dust, such as electric coal-fired boilers, waste-to-energy and biomass power generation boilers, and solid waste incineration rotary kilns.
