Where This Solution Fits
Qingfeng positions county-level waste treatment as its core business, serving sparsely populated regions in China and worldwide. Over 22 years of R&D have produced a complete technical system covering waste collection, transport, incineration and resource recovery, with the three-stage mechanical grate furnace solving incomplete combustion in plants under 300 tons/day.
Core Technology
The proprietary improved three-stage mechanical grate furnace is combined with a high-temperature flue gas treatment system to prevent dioxin formation and keep emissions well below national standards. Waste heat is recovered to produce steam for heating, hospital and hotel disinfection, and drying of wood or agricultural products.
Key Specifications
The system customizes treatment capacity to 50-300 tons/day and supports multiple waste types in one system. It handles high-moisture, high-ash, low-calorific rural waste while maintaining stable and efficient operation, backed by 50+ patents covering grate design, combustion processes and emission control.
