Electromagnetic Pyrolysis Furnace is a high-end process equipment that applies advanced electromagnetic induction heating technology to the pyrolysis process of materials. In an oxygen-deficient or oxygen-free environment, it uses a high-frequency/medium-frequency magnetic field to heat the furnace itself, thereby inducing a thermochemical reaction in the materials and converting them into biochar, pyrolysis gas, and pyrolysis oil.
Main Application Areas:
Solid Waste and Hazardous Waste Treatment: Oily sludge (extracting crude oil and achieving compliant dry residue discharge); Waste tires/plastics (producing pyrolysis oil and carbon black); Medical waste (harmless and volume-reducing treatment).
Biomass Energy Conversion (Carbonization): Converting straw, sawdust, nutshells, etc., into **biochar** and combustible gas for soil improvement or energy recovery.
Chemicals and New Materials: Pyrolysis of carbon nanotube and graphene precursors; Reduction and regeneration of special resins or catalysts.
The core of an electromagnetic pyrolysis furnace lies in induction heating and anoxic reaction. The working principle of an electromagnetic pyrolysis furnace is as follows:
Electromagnetic Induction: Induction coils are placed outside the furnace body. The alternating magnetic field generated causes eddy currents in the metal furnace wall, rapidly raising its temperature.
Thermochemical Decomposition: The material is heated in a sealed furnace chamber. When the temperature reaches the pyrolysis point (typically 400°C - 800°C), the molecular bonds of organic matter break.
Product Separation: Solid products (such as carbon black and biochar) are discharged from the bottom; gaseous products are separated into liquid pyrolysis oil and combustible non-condensable gas (syngas) by a condensation system.
Core Advantages of Electromagnetic Pyrolysis Equipment:
Extremely High Energy Conversion Rate: Energy acts directly on the reactor vessel, reducing heat loss from flue gas in traditional combustion furnaces. Overall energy saving is more than 30% higher than conventional heat treatment equipment.
Controllable Reaction Environment: Electromagnetic heating responds extremely quickly, allowing for instantaneous start-up or shutdown. Combined with a high-precision temperature control system, the pyrolysis gradient can be strictly controlled, thereby optimizing the yield of pyrolysis oil or char.
High Safety in Oxygen-Free/Reducing Atmosphere: The equipment has strong sealing properties and can be easily connected to inert gases such as nitrogen ($N_2$) for protection, ensuring safe operation in a highly reducing environment.
Green and Low-Carbon Production: Fully electrically driven, with no smoke, dust, nitrogen oxides, or sulfur dioxide emissions at the production site. When used with green electricity, near-zero carbon processing can be achieved.
Compact Equipment and Long Lifespan: The induction coil has no direct physical contact with the furnace body, avoiding the drawbacks of easy oxidation and damage of traditional electric heating elements, resulting in extremely high equipment operational stability.
