The "short" story of the small stove: the minimalist breakthrough of the small magnetic low-temperature incinerator
Next to the community garbage station, a silver-gray device occupying less than 10 square meters is working "low-key" - no smoke, no pungent smell, this small magnetic low-temperature organic matter incinerator is rewriting the rules of garbage disposal with a "short process".
Its "short" is the short processing link: at a low temperature of 300-500℃, magnetic energy activates free radicals to quickly decompose organic matter (kitchen waste, plastic, paper), generating combustible gas and heat energy; then the Fireprint technology is used to harmlessly treat waste gas and solidify heavy metals, and finally the heat energy is directly converted into electricity. If the garbage does not leave the community, the closed loop of "harmless → resource → energy" can be completed.
Its "fire" is the short market demand: the global pyrolysis market will exceed US$12 billion in 2025, and solid waste resource transformation has become a rigid demand under the dual carbon goals. Large cities rely on large facilities to "cover the bottom line", but towns, parks, and communities lack flexible "little helpers" - a scale of 10-50 tons of garbage per day can not only reduce carbon emissions from long-distance transportation of garbage, but also provide electricity and heat for the community, perfectly filling the gap of the "last mile".
But "short" does not mean "simple", and its "difficulty" is hidden in the details: although the nominal life of the magnet is 800,000 hours (about 91 years), the magnetic energy decays by 3%-5% year by year under high load, and new materials that are more resistant to high temperatures must be found; the efficiency of free radical decomposition fluctuates by more than 20% due to the influence of garbage composition, and a "composition-efficiency" dynamic model must be built; the efficiency of heat-to-electricity conversion is only 45% (lower than gas-fired power generation), and the power generation structure must be simplified.
In the future, this "short-link" small furnace may become the "green standard" of the community - solving the problem of small and medium-sized garbage, and can also form a "microgrid" with photovoltaic and wind power groups. From "burning garbage" to "producing energy", it uses a "short" story to tell the "long" future of solid waste treatment.
