Comparative Analysis of the Performance of Oil-fired High-Temperature Incinerator and Low-Temperature Magnetothermal Decomposition Device
In the field of harmless disposal of urban and rural domestic waste, oil-fired high-temperature incinerators are traditional mainstream equipment, while low-temperature magnetic-gas thermal decomposition devices are a new generation of green solid waste treatment equipment. The two differ significantly in energy consumption mode, incineration temperature, pollutant emission and operating cost, which directly determine the environmental benefits and long-term operation value of the project.
The oil-fired high-temperature incinerator relies on external fuel such as diesel and heavy oil for continuous combustion to maintain a high-temperature operating condition of 800–1000℃. The whole operation depends on external energy with high fuel procurement and transportation costs. High-temperature combustion easily causes rapid corrosion and wear of the furnace body and lining, resulting in severe component loss, frequent maintenance and high operation and maintenance costs. Meanwhile, intense high-temperature combustion tends to generate a large number of pollutants such as dioxins, nitrogen and sulfur oxides and dust, leading to high total exhaust emissions and heavy environmental treatment load, which cannot meet the ultra-low emission and carbon neutrality standards, only suitable for simple and extensive waste disposal scenarios.
Adopting patented magnetic field catalytic low-temperature pyrolysis technology, the low-temperature magnetic-gas thermal decomposition device requires no external energy such as fuel oil and electricity. It forms a closed-loop self-energy supply system by utilizing gas produced from the pyrolysis of organic matter in domestic waste for stable self-operation. The gradient low-temperature temperature control process avoids the drawbacks of high-temperature incineration and inhibits the generation of harmful substances such as dioxins from the source. Its total exhaust emissions are more than 15 times lower than those of oil-fired high-temperature incinerators, with emission indicators far exceeding industry standards. The device can fully treat mixed domestic waste without fine sorting, achieving thorough waste volume reduction. It has low wear, low failure rate and simple maintenance. Moreover, it can generate clean steam and power through waste heat conversion to realize waste resource utilization and income generation. Integrating zero external energy consumption, ultra-low emission and economic benefits, it is an optimal upgraded alternative to traditional oil-fired incineration equipment.
