HRDS: Source-End Dioxin Suppression at 850-1100C
How Qingfeng's HRDS high-temperature flue gas disposal system removes SO2 and HCl and suppresses dioxin at source for ultra-low emissions.

What is HRDS
Developed with the Dalian Institute of Chemical Physics, HRDS is a high-temperature flue gas purification additive that operates at 850-1100C. It removes SO2 and HCl, suppresses dioxin formation at the source, and achieves ultra-low emissions.
Benefits
Compared with traditional end-of-pipe systems, HRDS reduces reagent use, energy consumption and fly ash output. Qingfeng's source-end multi-pollutant synergic treatment achieves over 30% reduction in consumables, fly ash and treatment cost.
Intelligent control
Qingfeng integrates self-developed intelligent control with automated monitoring, enabling real-time adjustments based on waste composition and combustion conditions for stable operation and high-efficiency purification.
