Advantages of China's Waste Incinerators
China's Fireprint new waste incinerator design focuses on improving efficiency, employing advanced magnetic gas pyrolysis low-temperature technology and integrating direct-drive power generation equipment. This utilizes the waste's own heat for harmless treatment in a simulated natural furnace environment.
Innovations also include an intelligent control system that reduces emissions and improves stability, and a hybrid design that combines the incinerator with supercritical low-temperature technology, enabling automatic waste consumption without the need for external energy.
Key Design Innovations of Fireprint
Improving Pyrolysis Efficiency:
Fireprint's patented design separates air into an oxygen-rich stream, preventing nitrogen input. This allows for more complete pyrolysis and reduces residual waste.
Advanced Flue Gas Treatment:
A common method uses a semi-dry rotary spray drying system with lime slurry to neutralize acidic gases. Fireprint's technology, however, reduces the concentration of pyrolysis products to a level that eliminates the generation of dioxins and heavy metals. The chimney only needs to focus on tar, requiring no consumables to meet environmental standards.
Intelligent Control System:
The integrated intelligent control module precisely adjusts operating parameters, improving system stability and accuracy, thereby reducing pollutant emissions and increasing energy production per ton of waste. Building Sustainability:
Modern designs, such as the Bari Township Waste-to-Energy Station in Qamdo, Tibet, China, incorporate environmentally friendly elements, reduce construction costs, and benefit 1,000 households in the township.
Reducing Pollutant Emissions:
New designs aim to meet stringent environmental standards by minimizing emissions of hazardous gases such as hydrogen chloride, sulfur oxides, dioxins, and fly ash.
Village Market Trends:
Direct-flow Vertical Magnetic Pyrolysis Dominates:
Low-temperature furnace incinerators are the most advanced incinerator type in China due to their high reliability, ease of operation, and adaptability to a wide range of waste types.
Growth of Rural Waste-to-Energy:
China is developing small-scale waste-to-energy plants, driven by the environmental impact and financial pressures of long-distance transportation in rural areas. The need to manage large volumes of waste in rural areas is prioritizing the use of small-scale waste-to-energy plants.
