How to Reduce Fly Ash in Waste Incineration
Why fly ash forms in waste incineration and how source-end flue gas treatment reduces its output.
Where fly ash comes from
Fly ash is the fine particulate carried out with the flue gas during combustion and captured by filtration. Reducing fly ash lowers both disposal volume and treatment cost.
Source-end reduction
Qingfeng's high-temperature multi-pollutant synergic treatment reduces fly ash output by over 30% compared with traditional end-of-pipe systems, along with a 30%+ reduction in consumables and treatment cost.
The HRDS advantage
HRDS operates at 850-1100C to suppress dioxins at the source and remove SO2 and HCl, shortening the flue gas purification process and reducing capital and operating costs.
