1. Basic composition of SCR precision ammonia injection system

SCR reactor module, high-precision metering injection module, NOx/O ₂ /NH ₃ high-precision measurement module, pulse soot blowing control module, fully automatic reducing agent filling module, and intelligent Internet of Things module.
2. Precision ammonia spraying intelligent system

This system is a fully automatic intelligent system with unmanned operation; it automatically matches the optimal reductant injection strategy. It has dual threshold protection for urea level and compressed air pressure, self-diagnoses faults, and automatically stops injection. In the event of an unexpected power outage, compressed air outage, or compressed air shutoff, it automatically purges the spray gun after an emergency shutdown, effectively preventing gun blockage and allowing seamless continued operation after recovery. The system has a fault self-diagnosis function, allowing real-time viewing of its working status.
3. Anti-clogging function of spray gun

After multiple rounds of technical improvements, our company has successfully developed a spray gun anti-clogging device. This device automatically stops the urea pump from spraying and performs a purge to prevent the spray gun from clogging in the event of an unexpected power outage, compressed air interruption, or low compressed air pressure. Currently, our company is the only one in the industry to possess this patented technology.

4. High-temperature flue gas flow direct measurement technology

High-temperature flue gas flow direct measurement technology does not require the collection of equipment parameters or manual parameter input. It is resistant to high temperatures and dirt and can directly measure flue gas flow. It can also perform dynamic flow correction algorithms based on temperature and back pressure.
5. Precision ammonia injection + intelligent joint control technology

Real-time monitoring, analysis, and regulation of ammonia injection volume dynamically match operating condition changes to eliminate manual intervention errors; NOx emission concentration is stably controlled to meet the most stringent environmental protection policy requirements.
6. Professional technical team support

With CFD simulation calculation and analysis capabilities, we can provide customers with one-stop solution services to ensure zero-risk and high-efficiency projects.
