Now, the 52nd China International Paper Technology Exhibition and Conference (CIPTE 2025) is currently being grandly held at the Shanghai World Expo Exhibition & Convention Center.

As a professional manufacturer in the industrial high-temperature imaging field, we are presenting our self-developed infrared boiler monitoring system for recovery boilers at the exhibition, showcasing to pulp and paper industry customers an efficient and reliable boiler online monitoring solution.

Why Infrared Boiler Monitoring Matters in the Pulp and Paper Industry

The pulp and paper industry relies heavily on boilers in processes such as cooking and steam drying, and their operational safety and thermal efficiency directly affect production quality and energy costs.
Traditional manual inspection methods have long inspection cycles and slow response times. The infrared thermal imaging monitoring system developed by HTEC-video can monitor the furnace temperature field in real time, 24 hours a day, and visualize the internal furnace conditions.
Through highly precise temperature analysis, this boiler online monitoring solution helps enterprises promptly detect potential risks such as slagging, blockages, and uneven combustion, greatly improving recovery boiler monitoring safety and stability.

Key Features of HTEC-video’s Infrared Boiler Monitoring System

At this exhibition, HTEC-video is focusing on showcasing high-temperature thermal cameras and infrared cameras for harsh boiler environments, along with supporting image analysis software designed for paper mill boiler operations.

The infrared boiler monitoring system adopts 3.9 μm infrared imaging technology, combined with water-cooling and air-cooling protection and a high-temperature-resistant optical window design, capable of withstanding up to 2000°C, and can operate stably for long periods under harsh high-temperature and high-humidity conditions.
In addition, the system supports real-time data transmission and historical trend analysis, enabling operation and maintenance teams to carry out refined management and predictive maintenance for recovery boilers.

Advanced Protection and Automation

The core components of the entire infrared boiler monitoring system include an automatic retraction device and a slag removal device.
The purpose is to improve equipment automation, service life, and convenience, as well as to provide a clearer view of furnace conditions. In the event of cooling air interruption, power failure, or overtemperature, the retraction device will automatically withdraw the lens from the furnace to prevent it from being burned.
The slag removal device is designed to automatically clean the observation port of dust before the lens extends into the boiler, preventing contamination of the lens.

In addition, due to both splashing black liquor and large amounts of alkali and Glauber’s salt dust inside the furnace, the lens section is equipped with a dedicated cooling and purging method. A rotating air curtain is formed at the lens front end, increasing both the strength and coverage of the air curtain, ensuring cooling while also preventing furnace dust from splashing onto the lens—keeping infrared thermal imaging monitoring accurate and clear.

Mr. Zhu from HTEC-video’s technical team stated:

“The pulp and paper industry is placing increasing demands on boiler operational safety and energy efficiency. We hope to bring customers more efficient and safer production assurance through infrared boiler monitoring systems. This exhibition is not only a platform for us to showcase our technology, but also a valuable opportunity to have face-to-face exchanges with customers and gain a deeper understanding of their needs.”
