YOYO Solution
  • Flue gas
  • Urea injection
  • SCR reactor
  • Chimney (emissions meet standards)
YOYO Environmental Protection's excellent flow field design eliminates the need for additional induced draft fans and increases the heating furnace pressure, saving the owner a significant amount of energy.

Fully automatic intelligent system: This system accurately measures the amount of reducing agent injected by measuring flue gas flow, temperature, NOx concentration, pressure, and target denitration rate. Injection automatically stops if the urea level or compressed air pressure is low. In the event of a power outage, compressed air outage, or a shutdown, the system automatically purges the spray gun to prevent clogging and resumes operation once normal operation is restored. The system also features self-diagnostic functionality, allowing users to monitor its operating status in real time.

After-processing effect
  • NOx ≤30mg/ Nm3
    Processing efficiency over 99%
